its the same as generic labz X Mass, so here's some guff
The active compound in X-MASS is the real deal, 13-ethyl-3-methoxy-gona-2,5(10)-diene-17-one. Most are aware of this structure now, but it is definitely worth including in the Generic Labz offerings. This powerful said to be Tren-like product is legal because it is a progestin. X-MASS is a progestin structurally related to the so-called abortion pill RU-486. Some have stated that it acts like an "anti-progesterone" in lower dosages. Reports support the belief that X-MASS has a half-life of about 6 hours, though it appears that it's closer to 10 hours based upon plasma levels maintained in test subjects. It is not a 17-methyl alkylated product thus having very low potential for liver toxicity. Benefits: 1) Weight Gain 2) Increased Strength 3) Faster Recovery from ass kicking training 4) Non-17-alkylated
good luck
