I can actually verify that this stuff works. I had Cancer, chemo killed my natural Testosterone . I am on TRT , just 100 mg per week. I needed to do my 6 month blood work so I did my normal shot on a Tuesday but couldn't get blood done until the following Tuesday. That would or should make my levels low but I received my results and my total was 1187 , 1100 is the high normal by the way. Holy Shit it works.
