Yeah I had read that it had something to do with Cheque Drops, which is some hardcore stuff, but apparently that is erroneous.
It is the prohormone to tretolone, as stated by War. Trestolone is the 17a-methylated version of nandrolone. The infamous Deca. This is the 7a-dimethylated version of Deca.
So lets look at the nomenclature:
19nor should stand out, that means that it is nandrolone type compound. Think deca, not test pros and cons. On the phf site it compares this and Boladrol: Bola is the 7a-dimethyl version of methyl testosterone, Menta is the 7a-dimethyl version of nandrolone (Deca). The 17a-methyl version of nandrolone would be the aforementioned trestolone.
Ok sides are easy since this is a 19-nor: potential libido and erection issues, very quick shutdown of the HPTA (testosterone production, thus the male contraception thing...which I'll get to in a second).
Yeah so the information in vivo was done on rats and rabbits...I hate to say it but this isn't news. Most of us know, or should know, that we take these risks when taking steroids.
As far as the contraception thing goes- yeah well taking ANYTHING that shuts down the HPTA, including Hdrol all the way up to testosterone ester by injection can cause your body to not produce sperm. All of these compounds are going to inhibit testosterone function and development, its the nature of the beast. I have even seen articles where they were discussing at some point using HRT dose testosterone replacement for male contraception, since it is apparently very very difficult to reproduce while your body is not producing testosterone, even though exogenous sources exist. I know it was discussed, obviously they don't do this...
Positives- well if it is dosed correctly and converts to the target steroid enough, you will probably get the same 19-nor pros as you will sides. Some water, a bulker, great strength, excellent muscle building. Basically Deca.
That being said, I'm not going to try it. I'd rather just get something that has been used safely for decades and decades....and is a proven muscle builder, if I am going to go the 19-nor route.....Plus this is a dimethylated compound like Boladrol....I wonder how this is going to make liver values look.
Anabolic/Androgenic Ratio for Mentabolan:
Thats pretty dang high anabolic rating...this is rated compared to oral methyltestosterone. Double that of Superdrol (gotta compare dosing and androgen receptor binding though, remember) Androgenic rating is high as well, so great strength gains, potential androgenic sides like the libido stuff, hair growth or loss.
