he said it takes Thousands of IU to make a difference. It doesn't.
What I'm saying is that your friend has way too little experience with the compound to attribute anything to the GH for certain. 3iu's for 3 weeks? Come on now. That's 21iu total. I know VERY high level competitors who, for example, switch from one brand of GH to another and wonder if the new one is real or if the previous one was real, etc. It's fairly subtle and you're stacking a bunch of other drugs so it's hard to say, especially in a very short time frame like 3 weeks on very low dose.
What's the brand he's using? Chinese Generic?
