3-Alpha is androsterone
3-Beta is epiandrosterone
LG Reps does a bad job answering the right question in this thread. What do they know about MMV?
Which question was the right question?
I'm not sure what we didn't explain... but what else do you want to know?
Methyl Masterdrol (Version 1, albeit it was just called Masterdrol) was a Superdrol clone. Superdrol is Methyldrostanalone It hasn't been made by LG in years. If you want to use this, I suppose you could probably find some CEL Mdrol still lurking around somewhere. The stuff is harsh as heck, but you will grow like a weed and strong as an ox if you can manage to keep your appetite. Kiss your energy and libido goodbye. I could only handle 3 weeks. Don't be surprised if you get some gyno symptoms.
MMV2 and MMV3 are the beta and alpha isomer of essentially the same hormone. These both convert to the hormone Stanalone. Stanalone is a very strong androgen, it will have mild androgenic side effects (people with prostate issues, aggression problems, or are worried about hairloss should take caution when using it), but nowhere near the likes of the side effects methyldrostanalone. Stanalone should help the libido, raise strength, and increase muscle density. It is often used as a recomp hormone, and does well on a cutting cycle as well.
As it was said above, Liquid Masterdrol, MMV2, and MMV3 all convert to the same target hormone. They just use different methods of delivery.
If I didn't answer your question please restate it as clearly as you can and I will reply.
