Not sure what s the deal with that stuff, but it seems unless u r close to precontest shape it has no use. When I created a tread about hardness/vasularity drugs, many said EQ other MAST. EQ is great , no bloating - that s one amazing effect of it, vasularity too, besides the "deca dick" is great. Mast at 100mg/a day - not seeing anything, nada, zero....Not sure what you guys get out of it, besides maybe some striation on stage, the same u can get with winny....or maybe if you dont use EQ, or winny , or tren, then masteron will have visible effect.
