I have used both and prefer the M1-D, better gains. Anyone one else got a take on this?
I also only used the Methyl 1-D for 16 days, but ran the Epi for nearly 4 weeks all up.
I ran Epi for 6 weeks, all the way up to 70mg ED. I got energy from it, but that was about it. I noticed a distinct difference in the few weeks that I ran M1D. Energy was there, as well as the harder, fuller muscle.
