Rauwolscine is easily one of my top 3 supplements, but the brand you get makes a huge difference in terms of potency. Evomuse is super strong, olympus labs is a close second, SNS follows (and is 1.5 mg per pill as opposed to the others), and performax labs TA-2 max is probably the smoothest feeling (not nearly as stimulating but does the trick). Its too bad EBF isn't around anymore, the AAV2 was the absolute best rauwolscine based supplement I've ever had and the guy who ran the company was awesome.
