It's mostly overpriced crap like all the others. The supplement industry is a fucking joke... they're all hucksters and snake oil salesmen. 95% of the products are pure garbage. The marketing is aimed at young BBing neophytes.
Anyone here remember the marketing for MetRx and Muscletech? If you have any old mags from the 90's, go back and read those ads... absolute absurdity. I'll never forget the this one used to promote MetRx: "If is walks like a duck, it must be a duck." How about the one used to promote HMB: "Feels like Deca" - LMAO!
Save your hard earned money... spend it on roids, food, no frills protein powder, vitamins/minerals, creatine and caffeine.
