they are actua;;y not even pro hormones they are flat out steroids sir. but its true you shouldnt even contemplate usage till your 21.
for the question at hand you should know there is alot more then just superdrol and h_50 out there man. h-50 is getting great reveiws andall but i really havent seen any huge numbers yet from trusted sources. like 7 lbs a cycle. you wont get the same type of gains from SD and much of the others that you were used to with M1Teither. in fact i like these new ones better. weight goes on cleaner typically, alot less water weight and fat and the gains are easier to keep. id look into all the new ones and do some of your own research asking questions as you go to decide what interesets you most, thats what this site is for. try looking up max lmg, emax (ergomax-lmg), PP (phera-plex), prostanozol, finigen x, methoxy trn, along with your halodrol and SD. good luck and happy hunting.
ps i prefer phera plex
