Ah so you did use M1T... well methyl-1-test... is a steroid... and a hardcore one... from all the years of reading about PHs ('legal steroids' -- hah they are steroids) M1T was one of THE most powerful, 10mg will blow you the hell up... and from the posts of most even MORE powerful than superdrol.... for which on average people will run 30mg...
I'm not surprised then you got gains from it... The only thing maybe worse and more powerful would be methyl trenbolone or which you only need like 0.5mg to 1mg ED
And for any kids reading this naively thinking OH WOW more powerful... read more, it wasn't meant even for medical drug use, it was to test androgenicity of other steroids as it was SO powerful... instant liver failure to close to instant liver failure not unheard of. Fastest way to destroy liver. So yeah just putting warning up there for what I mentioned so someone dumb doesn't kill themselves...
