Yeah but he followed that up immediately with how high the concentration can be.
Anyways, this thread is kind of fucked... But I made a batch this week and have to say, was pretty impressive compared to test base injectable. 100mg per ml of DMSO gel works great. Really hit hard... I don't know if I'll bother with the hassle of injectable test base anymore, this is easier by far and works faster.
Fuck that. Injetion is superior to any transdermal (when your talking about your popular hormones.)
