Its actually a decent steroid Ive used it an know of around 5 guys personally that have used it and read around 20 or so logs from use on it.
Masteron is methylated at the 2 position and Superdrol is methylated at the 2 position as well as the 17
It changes its properties slightly and makes for a pretty clean bulker.
It isnt as harsh as anadrol on liver enzyme levels but people dose Abombs higher than SD.
SD provides nice gains for the vast majority at 30mgs ed most find back pumps can get harsh at 40mgs and I dont think anyone will need to dose at 50mgs.
It is terrible on Lipid levels though as with all oral steroids but it tends to be on the upper scale.
Its structure inhibits it from aromatizing and provides dry gains and has a tendency to increase glycogen retention to a high degree within the first 2 weeks and the majority of the weight gains come from then and start to slow down on week 3-4.
Its an interesting steroid if your looking for something less harsh than abombs and no water retention like Dbol to kickstart your cycles.
