I found this bit of info on the subject interesting:
Methyltrienolone is structurally similar to trenbolone (Parabolan/Finaplix), a well-liked and powerful androgen that does not aromatize to estrogen. The difference is the attachment of a 17-alpha-methyl group for oral activity. So one could refer to methyltrienolone as oral trenbolone. It was first explored quite some time ago by Negma in France, the same company that marketed Parabolan (trenbolone). But the drug was never approved by the French government and was hence never produced. The reason was extreme hepatoxicity (Liver Damage). Bill Roberts, the biochemist, once commented that taking methyltrienolone made taking insane doses of anadrol and Halotestin together look mild on the liver. That's why, to the dissapointment of many, you will never find a commercially marketed methyltrienolone product. Its only sold in bulk to labs and universities for research studies involving androgens.
Organic chemist Patrick Arnold, head of LPJ research, once stated that methyltrienolone was the most powerful steroid ever. While androgenically a very potent steroid, methyltrienolone is still basically trenbolone with a 17-alpha-methyl group. It's a potent androgen, with more binding than even DHT2.
What methyltrienolone, despite its amazing capacity, still doesn't overcome are the basic problems with any 19-Nor compound. First of all its effects on libido. Methyltrienolone still seems to affect our sex drive in such a potent manner that the dreaded Deca Dick (temporary impotence) is a very real threat. Another is that it still binds almost equipotently to the progesterone receptor. The latter would be of little concern as long as no circulating estrogen is present since methyltrienolone does not aromatize, but could cause problems such as aggravating water retention and gyno (growth of breast tissue in men) if combined with an aromatizing androgen like testosterone.
While many may wish that an incredibly strong androgenic, non-aromatizing compound as this was available for daily use, its not. And if the indications are true, its probably best. I've warned many people for the toxicity of fluoxymesterone, and everything points to it that methyltrienolone makes fluoxymesterone look like Tums tablets in terms of liver toxicity.
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.
