Do these compete for the same receptors? I think I read this somewhere but can`t find it again.

I'd like to see a write up about all the prohormones out and what receptor sites they use. if anyone knows of a link or feels like educating us.

This is BigCat's opinion (taking from BB.com)

With 4-diol you have too strong of a competition, vying for the same receptor enzyme. 5-diol is your best bet because of strong anabolism despite low conversion and the fact that it can upgrade the 3-beta enzyme assuring greater conversion.
