Just came off a run with HU Pharma Primo 100 and var... Both are as potent as I have tried.

Started Primo at 400mg/wk and bumped it up to 600mg for the last couple.

Despite having to take off 2 weeks mid cycle due to adrenal fatigue and taxed liver (ran back to back cycles with no time off) and not eating to bulk, my 5 rep bench increased 20 lbs in 10 weeks and had veins creeping out my front lower leg by the end of it.

Saw good results on 400mg (im 230 lbs...), but 600mg was a sweet spot! Abdominal fat melting off and abs poppin out more at that dose.
