I've done both Valopharm and PGP. I liked both, but, Valopharm was saddled with a bad reputation awhile back. Not to say that they haven't cleaned things up, but, I've never heard any complaints about PGP, so, you make your choice. I don't know about the 100mg/cc thing, Ive read that in order to have 100mg/cc of tren it takes too much BA to produce it therefore it irritates the hell out of the muscle after injecting? But, what do I know.....I did the 100mg/cc Finaplix from Valopharm, I can't tell if it was underdosed. I started of with 100mg eod, didn't feel much. Then did 75mg ed and what a difference.
