The color of the tops determines many things, like who made it and what to expect. Do some google searches you will see what I mean. Since posting this, I've went ahead and tried some blue top, and while it isn't Jintropin, it is Pretty Damn Good. I do not have any of the sides I read about at 2iu per day after 7 weeks on. I am leaner endurance is good, and had about a 10% gain in strength almost from week one. I once used yellow tops, CRAP! Yes caps do tell a story.
BK-in-Houston feel free to email me questions about HGH I've had a decent amount of experience.
