sometimes people ask then search, i've been guilty of it myself but
Yes prohormones work:
*4 andro/1 andro/nor andro bulking
*Epi andro/1andro cutting
(Just for some examples)
*You won't be able to prevent shutdown/suppression on cycle
*Probably count on spending at least $100-200 a cycle
*Have EVERYTHING you need on hand before starting
*Research the compounds you are going to use, including sides, cycle support, PCT, all that junk.
*Remember to also get joint support, as well as liver, BP, cholesterol.
*Train your ass off
*Eat right, semi clean, if you're an ectomorph you can get a bit dirtier in a bulk.
*If you're worried about having kids, male pattern baldness, all those other fun sides/consequences then maybe taking this plunge isn't for you.
