Homebrews even vary, it all depends on the quality of the powder/pellets and the competency of the homebrewer.......some kids can really fuck up a batch of Tren.....
Actually parabolan is what you're thinking john, and it was actually 76mg/1.5mls. It was a 1.5ml amp. Finajet, one of the original tren ACETATE preparations, i'm not sure but maybe it was 50mg/ml? Anyway, today it tends to be 75mg/ml for vet stuff, 100mg/ml for most kits and UG, and I make my homebrew at 150mg/ml for myself.
