"Tren" Designer Steroid Information / Write-Up
I wanted to put together a list of the so called “Tren” Designer Steroid compounds for anyone that might be thinking of planning a cycle. There are more than four molecular compounds that bear the “tren” name, two of which are the same but have different nomenclatures.
First and foremost, it is important to point out that the “tren” compounds are not prosteroids to the illegal AAS Trenbolone. They are similar as they are progestins. As Chad Brooks pointed out, the Esta-4,9-diene-3,17-dione molecule is the base molecule for trenbolone. (See the write up below for the Estra-4,9)
I’ve included some information on each compound that I felt was relevant from knowlegable sources, names of the designers and dosages per serving.
Any more information is welcome. I didn't include all the Designer Names or dosage information. If you have more info about a compound, please post it. Hopefully, when someone is searching for one of these designers, they can simply bring up this page via “search” and find what they are looking for. It would have been helpful for me.
17b methoxy trienbolone – progestin
Compound Information:
Posted by Big Cat - Methoxy-TRN or 17b-methoxy trenbolone information - Bodybuilding.com Forums
Designer Names: (most have been discontinued - some of these companies list the amount at 30mg. *If you have a link or source for the reason, please pm me or post it in this thread.*)
"I asked pat arnold, he said that when he tested it, it tested out to be Estra 4 / 19 Nor sooo i think im gunna go by that. which can be why its 30mg per cap. too bad only 60 cap bottles." (Edited for spelling/grammar)
Keep this in mind if buying the 30mg Trenadrol. It seems to be a different compound than the 3mg version.

PCT Information for "Tren" Designers - AKA Progestins
During my research into these designers, I caught snippets of info regarding PCT, specifically, which SERM to use. Many supported using Clomid as opposed to Nolvadex for gyno prevention.
Here's more from PCT and Cycle Recomendations: Estrogen, Progesterone and Cortisol control - Anabolic Steroids - Steroid.com / Anabolic Review Forums
Treatment of Progestin Related Gyno
According to some members writing in this thread, (Kristofer68SS and bigpapa) Cabergoline, Letrozole and Bromo can be effective to control progestin induced gynocomastia after the cycle. They are not used as a SERM like clomid to prevent gyno, but rather to treat existing gyno. L-dopa and P-5-P as well. "P-5-P is the active enzyme form of vitamin B6 that does not require activation by the liver." Feel free to post more info on this and I'll add it here.

17b methoxy trienbolone – progestin
Compound Information:
Posted by Big Cat - Methoxy-TRN or 17b-methoxy trenbolone information - Bodybuilding.com Forums
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).

Estra-4, 9-diene-3, 17-dione: Progestin - Dienolone Precursor

The active metabolite in this case is the nandrolone derivative Estra-4,9-dien-17b-ol-3-one and according to Vida, it has an anabolic potency equal to methyltestosterone and an androgenic potency 0.1 times... This has been referred to as a trenbolone precursor, however this is inaccurate because trenbolone has an additional double bond in the structure and the body does not have the capacity to insert this double bond.

Let me explain the evolution of this product.
In February of this year [presumably 2003 – edwards note] I engaged my chemist is china to secure me the starting material from which they make trenbolone. They replied with the Esta-4,9-diene-3,17-dione ,molecule. This molecule is literally the starting material for trenbolone and is two quick easy steps away. The only reason trenbolone is made is to make this base molecule more bioactive, the double bond and the alcohol addition make this base molecule more effective.
Esta-4,9-diene-3,17-dione is still very bioactive in its self and will bind
to the same receptor cites as Trenbolone. The conversion is only a very minor, minor, minor, minor part of its activity. This product is very effective, we are skating the FDA for now, it is classified as a hormone just like trenbolone, it will be banned eventually, but it is not a "Prohormone." It does not convert to your bodie’s hormones. This is a prosteroid, your body will use this molecule just like it uses steroids.
Thanks

13-ethyl-3-methoxy-gona-2,5(10)-diene-17-one - Progestin
Compound Information: (This is part of the generic writeup that every company used. I couldn’t find any expert opinions on this compound.)
What can users expect?
*Lean muscle mass
*Hardness
*Strength
*Recovery
Progestins do not aromatize to estrogens and being a 5-alpha-reduced analog prevents conversion to DHT. It is important to remember that being 5-alpha-reduced also means it is related to DHT. Hmmm, 5-alpha reduced means good high quality hardening effects, too. Naturally the lack of estrogenic activity translates into low water retention and solid gains.

PCT Information for "Tren" Designers - AKA Progestins
During my research into these designers, I caught snippets of info regarding PCT, specifically, which SERM to use. Many supported using Clomid as opposed to Nolvadex for gyno prevention.
Tamoxifen is a SERM, one of its known activities is to upregulate the expression of the Progesterone receptor. Clomid is a SERM, not really suitable for gyno treatment but at least it does not upregulate the progesterone receptor. It is effective for PCT.

One drawback to consider about Nolva is that it may cause progesterone receptors to become more sensitive. This means that while using progestins such as Deca or Tren, you may become more sensetive to progestin related gyno.
