Did you view those clips? And if yes what's your thoughts on them?
I looked a bit at the Masteron one. Basically they don't know anything, not saying as a put down, but they admit they just don't know because the data isn't there, all you can go by is trial and error and draw some inferences from what little data there is. Some with chem backgrounds make all sort of claims about the potency of compounds like Mast and Primo by looking at the shapes but as we don't have that education we can't say shit. Like one fella wrote a book about Primo and said it was very weak and there were "fights" over it LOL.
