wtf? lol, don't drop the primo! That's the best part of this cycle. It's completely neutral to libido and sides! You'll only feel good on this stuff. The best lean gainer I've ever used. Do you only have access to 4 weeks worth of test prop? I don't understand your logic.
You're going to run out of spots to pin if you inject prop and primo ED. Do the primo twice or three times per week.
Do this:
WK 1-14 Test E or Cyp @ 400-500 EW (or your test prop regime)
WK 1-14 400mg Primo EW
WK 8-14 Var 50mg ED
WK 5-14 250iu HCG 2xEW
PCT 16-20 4 pumps Sustain Alpha ED
You'll be insane. Have fun!
