have not been taking long enough to rate igf boost, but so far does seems to have a relaxing effect, helping to at least rest at bedtime..
Great Pump. and helps with recovery times
Have only been taking this for 2 weeks but I definitely notice better quality of sleep which I attribute to my strength gains in the gym. Bench is up 10 lbs and reps on deads have increased slightly. I'll give a full review after I complete the bottle. Not stacking with anything else.
It took a couple of weeks before I noticed anything but it definitely helps with recovery.
Great pump after the first week! Tighter core starting to be visible by week 2. Great product.
