look... stick to what is tried and true.. those things with the most data and real world feed back. SARMs are new but just like a designer steroid. the possibilities are pretty much endless. but there is NO real track record to follow.. yet OG anabolics offer you tons of anecdotal evidence to go by with more blood work than you can shake a stick at..
I'm old school
I feel you can gain slowly over time and do it quite safely if you start small and work your way up..
you could find some andro products to "dip your toes in the water" so to speak.. see if you even like it. some people dont.. from there you can slowly work up the "food chain" of hormonal manipulation and pretty much go as far as you can possibly get in the 15-20 yr time frame. SAFELY
if thats unexceptable, you will want to start with a ton of test, tren and anadrol or the likes. ruin your liver and crash your epi:test ratio. self castrate and pretend your happy with your gyno and shrunken bawls.
