gnc protein comparison

GNC has been an established retail chain selling health and nutrition related products including vitamins, supplements, minerals, herbs, sports nutrition, diet, and energy products since the 1960’s.  They are a combination of corporate-owned and franchised stores all across the world. A local GNC is the most common store that someone new to the fitness world goes to.  I know I found myself going to my local GNC and spending hundreds of dollars on a monthly basis building and establishing my supplement stack.  What really stuck out to me was the amount of money I found myself spending on a month supply.  Are these supplements better than the ones at my local grocery store?  Are other supplement companies out there offering quality products for a better price?

Looking at the products offered by GNC, they have a core line of their own supplements they sell.  You’ll notice when visiting a store and asking for help, this is where your friendly GNC employee will direct you because they make a commission off these items.  Let’s use protein powder as our example to see what GNC offers versus what else is on the market.

GNC Protein Powder

Arguably the most popular GNC supplement is their Pro Performance AMP Amplified Wheybolic Extreme 60.  That’s quite the catchy name.  Without a sale being ran, a three pound tub will run you $54.99 for the original version.  $59.99 for the “ripped” version.  The three pound tub is the only size available and you get 51 scoops per tub.  You do get quite a few flavors to select from such as Chocolate, Vanilla, Cookies and Cream, Strawberry, Peanut Butter, and Salted Caramel.  It’s been several years since I’ve tried this protein, but I remember the Chocolate flavor being ok.

For each scoop you are consuming 90 calories and have a macro nutrient breakdown of 20 grams protein, 2 grams carbohydrates, and half a gram of fat.  The protein sources are made up of Hydrolyzed Whey Protein and Whey Protein Isolate.  You also are getting a small dose of L-Carnitine and an Amino Acceleration System which is more of an enzyme matrix for improving digestion of this protein.

Now let’s look at GNC’s mass gainer Pro Performance AMP Amplified Mass XXX.  $49.99 for a 13 serving tub that comes in the flavors of Chocolate, Vanilla, Cookies and Cream, and Strawberry.  A full serving is four scoops giving you 750 calories, 50 grams protein, 123 grams carbohydrates, and 6 grams of fat.  You also get HMB and Creatine but it’s a prop blend, so you don’t know how much of each you’re getting.

These GNC protein powders do appear to have a solid profile on them but you are paying a hefty amount for each.  Easily over a dollar per serving which adds up.  What GNC has going for them is a brand name many people know and you are going to pay extra just for that brand name on the tub.  To be fair to GNC, they have a rewards program however the high prices mealy come down to barely meeting the competive prices of other high quality proteins available on the market.

What about other retailers and protein powders?

Plenty of other retailers are out there, it’s just a matter of looking.  Big grocery stores like Walmart, Walgreens, CVS offer supplements and protein powders, however looking at the brands and quality, they are marketed towards the general public. These are very basic products, and normally are not high quality. It’s recommended to look at retailers that specialize in sports and nutrition supplements for finding the higher quality and better formulated products. was originally the top place for purchasing supplements online however they have been on a major decline over the last several years of less deals, higher shipping costs, and longer shipping times, and they just dropped a bunch of brands.  Variation in product from is the lowest it’s been in several years.

In comparison, Suppz has been on the rise with more and more brands being added and new store locations opening.  Suppz began as a gym in the small town of Fennimore, WI.  The gym had a small shop which eventually transitioned to an online store that does business in 94 different countries as well as local brick and mortar locations in the state of Wisconsin.  High quality products for competitive prices backed by great customer service.  A rewards program was recently incorporated to save customers even more.  One of the first things that stands out about Suppz is that they will price match any competitor selling the same product for a lower price.  Yet one thing you will notice is you won’t find yourself asking them to price match often because the prices are already some of the best on the market.  But the big question you may be asking is: what is the quality of the products they sell?


Nutrabio is a company that’s really been changing the supplement industry with the amazing quality and 3rd party testing they use on every batch of product they produce.  In the supplement industry, without 3rd party testing verification, you don’t know that what you’re looking at on the supplement label is really in the tub.  This 3rd party testing verified every product meets label claims and the customer can feel safe knowing what’s listed on the product is what’s in the tub.  Some companies over the past several years have been caught going the cheap route not putting the full dose in the actual product.

Nutrabio offers a whey protein isolate, whey protein concentrate, micellar casein, and mass gainer protein powders.  All of which are produced in a GMP facility and are FDA inspected.  Nutrabio’s most popular protein is its Classic Whey which is gluten free, 25 grams a protein per serving of whey protein concentrate and only 130 calories.  Available in several delicious tasting flavors such as Chocolate, Vanilla, Strawberry, Salted Caramel, Chocolate Peanut Butter, Cookies and Cream, Cake Batter, Pina Colada, Cold Brew Cappuccino, and Horchata.  In a two pound tub you get 27 servings for $32.99.   A five pound tub provides 66 servings for $59.99.  Buying in bulk will save you money and you’re paying less than a dollar a serving for one of the highest quality, tested and verified protein powders on the market.

MTS Nutrition

MTS Nutrition another high quality company that has firm belief in 3rd party testing.  They offer a wide range of supplements but MTS Machine Whey is arguably the top selling product of the bunch.  Formulated with high quality ingredients and produced in a GMP manufactured facility.  Machine Whey is packed with 25 grams of protein and moderate carbs and fats to range between 150-170 calories per serving depending on which flavor you purchase.  You also get a big dose of leucine, over 5 grams of BCAAs, and immunoglobins and lactoferrins to support immune function.

Two pound tubs come with 23 servings per tub and costs $29.99.  Or you can opt for the more cost efficient five pound tub with 67 servings for $54.99.  Besides the excellent profile, the biggest draw of customers purchasing Machine Whey are the flavors.  Flavors include Chocolate, Vanilla, Cookies and Cream, Peanut Butter Cookies and Cream, Mint Cookies and Cream, Red Velvet Cake, Apple Pie, Strawberry Cheesecake, Banana Cream Pie, Birthday Cake, Peanut Butter Fluff, Blueberry Muffin, Black Forrest Cake, and Pumpkin Pie.  I’ve tried a majority of the flavors and they are all absolutely fantastic!

Other cost efficient and quality options

Besides the two brands and proteins I’ve listed above, you can find plenty of other fantastic quality and tasting protein powders on the market that are very cost effective.  I’ve compiled a list of just a few popular proteins and the prices you can find them for at any Suppz location or on the website:

Brand: Dymatize Iso-100

Price: 1.6lbs – $29.99, 3lbs – $49.99, 5lbs – $74.99

Flavors: Gourmet Chocolate, Gourmet Vanilla, Strawberry, Cookies and Cream, Banana, Birthday, Cake, Chocolate Peanut Butter, Peanut Butter, Fudge Brownie, Cinnamon Roll, Chocolate Coconut

Description: One of the most popular isolates on the market and for good reason.  Only containing 110 calories per serving, 25 grams protein, and no carbs or fats.  Backed up by fantastic taste, you are getting exactly what you pay for.

Brand: Nutrakey Whey Optima

Price: 2.4lbs – $28.95, 5lbs – $51.95

Flavors: Chocolate Lava Cake, Vanilla Ice Cream Cookie, Salted Caramel Peanut Butter Cup, Cookies and Cream

Description: Quality backed by a quality company, Nutrakey produces a very healthy and clean protein powder with very good flavoring.  120 calories and 23 grams of protein with only 3 grams carbohydrates and 1 gram of fat.

Brand: Purus Labs MyoFeed

Price: 2lbs – $27.95, 4.4lbs – $54.95

Flavors: Chocolate Cookie Crunch, Homemade Vanilla Wafer, Mom’s Strawberry Milkshake, Maple Butter Pancake, Chocolate Peanut Butter, Vanilla Peanut Butter

Description: Purus Labs prides themselves in releasing products that have been tested, every batch.  The first and only brand to incorporate PB2 (a popular powdered peanut butter brand) into the flavoring of their protein.  Only 120 calories for 23 grams of protein, 4 grams of carbs, and barely over a gram of fat.

All of these protein powders listed are high quality and clean protein powders backed by fantastic flavoring.  Check out the website or any store location and you will find Suppz has plenty of other options that are even more cost effective that may be on a monthly sale.  Speak with the employees livechat, or email [email protected], and they can give you information based on personal experience with each one to help you find the protein that fits your diet perfectly and one you will ENJOY the flavor of.

Reviewing everything above, GNC protein compared with all the other proteins considered does have a higher cost to them.  All protein powders I’ve mentioned including the GNC protein has an excellent ingredient profile, good taste, and will benefit the user.  The biggest difference is the price.  When I’m shopping, I do want what’s going to be of most benefit to me.  But paying a higher price for the same results as I can get from other protein powders, I’ll opt for a combination of high quality, great taste, and what’s cost efficient so I can use the money saved either on the other supplements I need to re-up on or enjoy some extra money I can spend elsewhere.

The main takeaway I want people to take from this entire article is that paying a higher price for your protein powder does NOT mean it’s better.  Paying twice as much for the exact same item does not change the fact the higher priced item is the exact same.

amino energy vs charged amino

Optimum Nutrition’s Amino Energy has been on the market for several years and has been a big hit.  Offering a very basic formula that is an excellent replacement for coffee and soda.  It’s very versatile and can be used as a mid-day pick me up or as a pre workout or intra workout supplement.  A variety of over 13 good tasting flavors has been what has really kept Amino Energy on top of the market and selling well in the category of an amino blend with caffeine at a very cost effective price.

The latest release of NutraCharge Charged Amino is the newest and toughest competitor yet to Amino Energy and offers additional benefits not found in Amino Energy.

Before getting into a comparison between these two brands, lets first take a look at the importance of Essential Amino Acids (EAA’s) and Branched Chain Amino Acids (BCAA’s):

Essential Amino Acids (EAA’s)

EAA’s are essential amino acids that aren’t produced by the body and must be taken in by food or supplementation.  EAA’s consist of nine amino acids.  Consuming essential amino acids results will stimulate protein synthesis.  This means your body can either grow more tissue or reduce the amount of protein breakdown.  Certain amino acids help with supporting your metabolism and improve physical performance.  They have even been shown to reduce the effects of aging.

  • EAA’s prevent muscular breakdown during periods of intense physical and mental stress
  • EAA’s improve, enhance, and protect the mitochondria(energy within our cells)
  • Curb hunger and improve metabolism

Branched Chain Amino Acids (BCAA’s)

BCAA’s are made up of three amino acids: leucine, isoleucine, and valine.  These amino acids aid on preservation of muscle glycogen stores.  This means users can work out harder and for longer with glycogen stores lasting longer due to the quick absorption of BCAA’s.

Which is better?

Comparing what each are, it might seem obvious that EAA’s are much more valuable to a performance athlete or gym rat just based on the fact EAA’s already contain the three amino acids found in BCAA’s along with the additional amino’s your body cannot produce.  Research also backs this as EAA’s are able to stimulate muscle protein synthesis while BCAA’s fall short of this.  So this tells us EAA’s are more beneficial for the recovery process.  This does NOT mean BCAA’s don’t have benefits.  The benefit of keeping glycogen stores readily available to your body will benefit an athlete, however when comparing EAA’s and BCAA’s, EAA’s is the wiser choice to invest your money in.

Charged Amino compared to Amino Energy

So what does all the above mean in regards to Amino Energy vs Charged Amino comparison?


To start with, both contain 100mg of caffeine per serving, however the caffeine in Charged Amino comes from natural sources such as green coffee bean and green tea extract.


Charged Amino contains 5g of EAA’s with the primary amino acid Leucine, which can be known as the anabolic trigger.  Leucine is the leading ingredient in a 2:1:1 BCAA blend.  The leading ingredient in Amino Energy is Taurine.  Based off the profile, Charged Amino will be more beneficial at stimulating muscle protein synthesis.


Charged Amino includes a hydration blend including electrolytes.  One of the only caffeinated amino products on the market to include electrolytes.  Hydration plays a big role in performance in your sport or gym performance allowing the customer to perform up to their full potential.


Amino Energy has over 13 flavors available while Charged Amino currently only has 3.  With Charged Amino being a new product to hit the market, you can bet they will expand on the flavors.  Amino Energy tastes fantastic and has the backing of being around for several years.  Charged Amino is currently being samples out at all Suppz locations to allow the customer to taste for themselves and feedback has been very good on all 3 flavors.


The price of a single tub of each is the same at $19.99, however you can save money by buying 2-3 tubs at a time.  Suppz, and most brick and mortar retailers offer quantity discounts and freebies on Charged Amino for buying multiple units.

Who wins?

In my opinion, it’s win-win for customers.  The three available flavors of Charged Amino is well worth the buy over Amino Energy.  Taste and ingredient profile makes this a rather easy victory for Charged Amino.  The better cost as well really makes it an easy choice.  Charged Amino only falls short with regard to the amount of flavors available.  If your goal is the best possible performance you can achieve along with outstanding taste, go with Charged Amino.  If you are okay with sacrificing performance and paying a little extra for flavors Charge Amino doesn’t have, then Amino Energy is likely your pick.

Authors choice: Charged Amino

lipodrene vs hydroxyelite

Hi Tech Pharmaceuticals is known for pushing the envelope on many things when it comes to creating hardcore supplements. Leaving no doubt that a product will pack a punch and leave the user feeling the effects of their stimulant driven products, they have rolled out numerous pre-workouts and thermogenics that are known for being some of the hardest hitting on the market.

Synadrene VS Synadrex

For years, Metabolic Nutrition Synedrex has been one of the most legendary thermogenics and energy products the industry has seen. Having undergone a reformulation before being temporarily pulled by Metabolic Nutrition, anyone that is familiar known the power of Synedrex knows that it’s no joke and a powerhouse of a supplement. In light of the latest hiatus from the market, Hi Tech has once again done their trend of playing it dangerously close in terms of creating a copycat product that is almost identical in name and formula with a few alterations to improve upon the original, much like they did with Jack’d Up and Hydroxylite Pro, both of which are USPLabs product clones.

Chain’d Reaction is the new BCAA product from APS.

APS has gained in popularity over the past year due to products such as their pre-workout, Mesomorph, and pro-hormone, Androbolic 250. Their new product, Chain’d Reaction, is a BCAA and EAA blend.

The top selling points are its high dosed blend (7.5g of BCAA’s compared to the normal 5g blend) and the protection of BCAA’s by Alpha-Hydroxy Acid, which does not cause an insulin spike.

In addition, Chain’d Reaction is ultra-micronized which makes it extremely soluble and fast digesting. It also means it mixes really well and won’t settle at the bottom of your shaker or leave a powder residue!

The Evolution of Renny D

If you’re anything like me, you know that walking into a gym for the first time can be intimidating. What is also equally intimidating is when you walk into a supplement store for the first time. This can be your traditional bricks and mortar store or an ecommerce website. For some time, I would walk into a local supplement store and purchase items I thought I needed based of the recommendation from a supplement “professional” or a magazine ad I saw. Sound familiar? The following blogs from me will help assist you in getting honest feedback and reviews from supplements. This is not a magazine ad. This is not a TV commercial. This is the cold hard truth on supplements.

People are often skeptical when a new supplement is launched, and rightfully so. Especially when it contains an ingredient that hasn’t really been in many supplements before.

This is the case with Muscletech Phospha Muscle, with the main ingredient being phosphotidic acid. (And it’s a bit pricey too)

You can see the claims from Muscletech in this video about Phospha Muscle:

Basically phosphotidic acid is naturally produced in the body during resistance training, and supplementing with more of it can increase protein synthesis.

In one study, subjects supplementing with phosphotidic acid gained 5.3lbs of lean muscle in 8 weeks, twice what the placebo group gained.

We decided to put Phospha Muscle to the test ourselves, and see if it really worked like in the study above.

Follow the journey below to see Suppz athlete Evan’s Phospha Muscle review.
(Keep in mind he only did a 4-week run of Phospha Muscle, not 8 weeks like in the study)

Evan is a Men’s Physique athlete who has been training for about 7 years, so no noobie gains here.


Evan introduces himself and tells you about his background, and what his plans are with Phospha Muscle.

Week 1
  • Gained about 1 pound
  • Seems to be more sore

Week 2
  • Gained 2 pounds (added about 120 calories from carbs each day)
  • High intensity in the gym
  • Still more sore than normal

Week 3
  • Lifts going great
  • Bodyweight stayed same
  • Strength has been increasing
  • Good energy in the gym

Week 4 (Conclusion)
  • Gained 7lbs over the 4 week trial

So it looks like the Phospha Muscle claims held true!

While somewhat expensive, if your diet and training are both in check, this could be a great addition to help you gain lean muscle mass.
