I’ve been running super primo200 sustanon 250 from Nakon for 3 months. I have found that out of the different makers I have used this is the easiest on my body and not giving me pip as some other brands do. Spread out my eod sust to 700 mg weekly and about 475 mg primo weekly from Nakon medical. I really think that Nakon is one of the better brands I’ve used. The gains have been solid and consistent and the primo has kept estrogen low and my physique lean. Couple this with a low dose TBOL cycle I will be running for 5 weeks before I finish I am very happy so far. Recommend Nakon Medical.
