Stacking and Use:
Obviously this section is mostly useless, as any who would use, let alone stack methyltrienolone for any decent period of time, wouldn't really be around long enough to tell us how well it worked. Ideally one would use it alone, while dieting or for the purpose of gaining lean mass. The androgenic potency is slightly higher than that of trenbolone, so the risk for aggravated hair loss, acne, prostate hypertrophy and deepening of voice is not only realistic, but almost likely. If one were to use it, you would probably have to use every trick in the book to protect your liver and stay alive: Alpha Lipoic Acid, Milk thistle, dessicated liver and Vitamin B6. The blood pressure raise would not be mild either. So something to lower blood pressure is advised as well.
Of course the best advice is to refrain from using such a compound, although for 99% of the population that is not a problem, and I would assume that the 1% that does have access would know better.
