Brovel prop is usually enathate. Given your choices...I would go with the QV, I've used their winstrol and enathate. The enathate is surprisingly non-painful for cheap vet gear. The winstrol is as painful as any, a pain in the ass to draw up, but I think it is overdosed. I only use low doses of winny, like 12 mg a day, but within 3 days I was harder, more vascular and had sore joints. By the end of week two my hairline was already receding. A couple other friends used some from the same batch, and they all commented on how quick it seemed to work compaired to other cheaper brands. I would compair it to zambons (my favor... but of course I can use an insulin syringe with zambons, so they still rule).
