Not a clue what a still avajlable, but mbps dark Rage was my favorite. I used to get the others free, but hi liked dark rage so much that no actually paid fornit3 lol. Shit was liken60$/jug used to getnthengrape. Dunno what was in it but shit was strong. Had to shit one day before training and blood just started pouring out my nose while sitting there on my phone. Wasn't even straining (pre workout shits ffs). Get up and notice my face/neck/chest/shoulder area was purple... So purple people were mentioning I was more purple than usual and calling me "Barney" lol... Next day the same ahit happened. Nose bleed, purple, etc. Took 2 scoops those times, then i read the label/directions and it said something like "if you're usingbthisnproduct for the first time or sensitive to caffeine(or whatevrr) syltartnwith 1/2scoop".. Regular dose was 1 scoop... And at yhe time I really wasn't using much for preworkout stuff otherbthanbsuper-thick instant-coffee &sugar (prison version ofpre-workout).
