Hi all, I've searched through the 'Educational Threads' and didn't find anything relating to my question.

Reading through this site provides a lot of information. I've come to learn a few things, certain steroids hit certain receptors etc. I can recite this to people, but I don't really understand it.

So my question: where can I read up on receptors, what they are, how they work, why they become used to certain compounds(Clen) and need cycling? Which steroids hit which receptors, can you use multiple steroids that hit the same receptor?

It's a biggie I know. Are there certain books I can buy to learn more on this topic?

Many thanks in advance!
