TweetUsed the old NO Shotgun for over a year, best pre workout I ever used....since then I have tried Dust by Blackstone Labs (one scoop is too strong for m), Nirtamine by Myokem, Pre Cre by Muscle Elements, Jack'd Up by Hi Tech (makes me feel like crap) and BSNs Hyper FX. Half a scoop of Dust with a scoop of Nirtamine is what I found works best for me. Plus 2 grams of creatine, 5 grams beta alanine and 5 l-cirtrulline, I am ready to train. Then I will switch up in a month or 2 to Pre Cre or Bsn's Hyper FX.
