I cannot say I am 100% sure I know what the compound is. I am, however, fairly certain my initial assumption is correct. If someone would be willing to send me a sample, I will find out its exact structural formula.
My reasoning is as follows:
1.) The original claim for M-TRN is that it is 4x more anabolic and androgenic than tren ace. Such claims can only be made with supporting data. According to Vida, tren ace has been given a value of 500 in regards to its anabolic and androgenic potency. In comparing tren ace to other 4,9,11-triene steroids, only one was documented as having a value of 2000 in relation to its androgenic and anabolic potency. This molecule was also orally active without 17alpha alkylation. This molecule has a MOM ether group protecting the 17beta hydroxyl group. If a person does not understand correct nomenclature or wants to decieve the public, it would be easy to simply call it a "methoxy group."
2.) Steroid ethers are *explicitly* stated as being illegal in the steroid control act. If M-TRN was truley "methoxy trenbolone", it would be highly illegal to import, sell, purchase, or consume. I don't believe ALR would put himself at such an incredible risk.
3.) According to literature, 17beta methoxy steroids are very easily hydrolyzed (even more so than esters). It simply wouldn't survive the first pass liver metabolism if consumed orally.
It is very easy to conclude from these observations that the structure of M-TRN is actually trenbolone with a MOM 'ether' protect group.
Yep what you say seems to agree with what BC sayed over bb.com:
Not sure how relevant this is, since I've never seen the product mentioned on this board, but there seemed to be some confusion regarding this compound on other boards, so I figured in light of the fact that it could concern the health of users, I would post it here as well.
The company ALRI, some time ago, released a product called Methoxy-TRN. It never appeared on their site, it was quickly pulled from all sites selling it and all the write-ups about it were removed just as quickly as well, which may also go to establish that this issue may not at all be relevant. But some people in this day and age of hording designer steroids decided thy wanted to stock up.
The problem was that Author L.Rea (I don't really understand how he is connected to ALRI, is he an associate, employee or the owner ?) seemed to have made claims in regards to the product based in certain VIDA scores. On muscle guru's Bruce ******* aptly pointed out that the compound that is in methoxy-TRN, namely 17bmethoxy-trenbolone is not listed in VIDA, instead the scores cited by Rea were those for an entirely different compound namely 17b methoxymethyloxy-trenbolone. This is not entirely unusual behaviour for author L.Rea, he has a fairly poor reputation in the science-minded community for pulling things out of his ass. Anyone who has read either of his books will have to concur with me the man doesn't know what he is talking about when it comes to steroids.
However because of this, some people seemed to believe that the scores cited by him applied for Methoxy-TRN, which is not the case. On a side note, the scores in vida are obtained through now defunct rat tests and in no way match real life anyway. But that aside.
On muscle guru's however in the same post, Bruce ******* made an equally erroneous assumption by saying that 17bmethoxy trenbolone (basically trenbolone with a methyl group on the 17b-OH) is an ester and would yield free trenbolone. It is however not an ester (alcohol function with an acid function) but an ether (alcohol with alcohol). An ether-bond isn't really reactive at all, that is why steroid ethers are listed as separate compound (quinbolone for instance is an etherized boldenone derivative).
The methoxy group is not metabolized to any significant degree at all, in fact its quite a common group. Not among androgens, but among progestins. The work 'CFA analysis of steroid libraries' by Ojasoo and Raynaud demonstrates that this group has a tendency to strongly reduce androgenic binding and drastically increase progestagenic binding and specificity. Really interesting if you know that trenbolone is already a very strong progestin.
An older study by the same researchers, entitled 'Unique congeners for receptor studies' clarifies the whole situation in detail. It summarizes the RBA's of several steroids for the 5 classical nuclear receptors. In this study we see that :
1.Trenbolone has 125-150% the RBA for the androgen receptor as opposed to testosterone, and 50-75% the RBA of progesterone for the progesterone receptor.
2.17b-methoxy-trenbolone has only 15-25% the RBA of test for the AR, but has 250-600 % the affinity of progesterone for the PR.
That means ALRI has managed to put out a product and sell it as a potent anabolic that was 5-7 times less anabolic than the parent compound, and 4-12 times as progestagenic. That is when the original molecule was already a potent progestin. More evidence to the weak anabolic and strong progestational nature of these products can be found in other compounds that are basically well know androgens with an added methyl group at 17b-OH, like methoxynandrolone, which had virtually no affinity for the AR.
This just for whom it may concern. The bottom line is that methoxy-TRN is 17b-methoxy-trenbolone and IS NOT 17b-methoxymethyloxy-trenbolone, and will not yield free trenbolone either. Its a very weak anabolic with an extremely strong progestagenic activity (up to 6 times that of progesterone itself).
