dunno which i would want to use in upcoming cycle.....i plan on running deca at low dose like 200-300 mg a week for 10 weeks the sides kill me at high doses or should i run primo 300-400 mg a week for 12 weeks of course i will run test e at 500-750 mg a week for 12 i got all the pct on hand and hcg as well....have never run primo but have heard its a waste of time and money unless doin 800 mg a week to me that sounds a bit excessive
