OK, 2 questions, with 2 answers.
Golden Muscle, I feel Masterdrol and M1T serve 2 totally different purposes, others may disagree. As a juicer, I have used M1T to jump a cycle, and personally feel it is superior to Dbol in reguards to fast results. However, if I was to do a "comparison" I would call M1T similar to Dbol.
M5AA OTOH, I suggest for those looking for a "dry" type cycle, or those looking to cut. If I was to compare it to an Anabolic Androgenic Steroids (AAS) I would compare it to winny.
So, for myself, much as I wouldnt run Dbol and Winstrol (winny) together, I wouldn't run M1T and M5aa together, because both have different results.
M1T= extremely fast *gains* in reguards to water weight, and some significant sides
M5AA= Slow steady "dry" gains with a significant increase in strength. No, you will not put 10 pounds on in 10 days with M5AA, but you ket steady keepable gains, and do not deal with the 10 pounds of water weight loss that you experience with M1T. Also M5AA definetly has a great hardening effect, again, similar to Winstrol (winny) IMO.
