Ok thanks bro
I remember 15 saying that dbol and drol raise igf
15 wasn't a "mechanism guy" guy either, to say the least

People were critiquing him because he didn't know extra special things they thought a "pro" should know. 15 was a comedy account and there was definitely someone there who had used extensively. Pro or not.
Fact of the matter is pros in general do not "know" much about drugs and don't have to. They just talk among themselves and then some approaches become trends. The trend has mostly been "more" though

Several times "nerds" have introduced some concepts, like from Duchaine on, now it's IG shitfluencers, the more nerdy types.
This is the "Primo and Mast" phase.
