hey guys, Im currently in the 6th week of my cycle:

600mg EQ/wk
100mg test P EOD
400mg Masteron /wk (inj EOD)

so far great gains, my bodyfat has shrunk down substantially, strength gains huge.. finally benching 4 plates.

age: 20
height: 5'10
weight: 205

Ive just changed the lab I get my masteron from, and ive been noticing acne break-outs on my back... which hadn't happened with the Masteron I started with. Could this be directly related to the new gear or is it just side-effects naturally occuring? should I discontinue the masteron for now to see if the bacne goes away?

I know theres not much you can do about it, but any tips would help.
