that's quite a bit. primobolan at that dose (only if affordable) would be a better choice imo.
i've used both at around 300-400mg/wk with test, and i think the primo is actually a stronger product. Plus, it seemed to enhance the "separated" look of the muscles more so than the masteron. on the other hand, Masteron gives a great mood elevation, and good density to the physique. i guess i just prefer the primo. but, you can get like 4x more masteron for the price of primo...so there's definitely a cost difference.
never tried any DHT based oil above 400mg/wk, but may experiment in the future.
