MESO-Rx Exclusive Unique characteristics of MENT

[MESO-Rx Administrator]

MESO-Rx is pleased to announce the publication of part 4 of an eleven-part series by @Type-IIx highlighting the unique features of various anabolic steroid compounds. The fourth installment focuses on MENT (trestolone).

MENT (trestolone) is an anabolic steroid with potent estrogenic and progestagenic effects, causing gynecomastia, fluid retention, and increased blood pressure. It is generally unsuitable for bodybuilding purposes.

MENT Insights: Unique Characteristics of Anabolic-Androgenic Steroids – Part 4

Learn about the unique features of MENT, its effects on body, and why MENT is not a commonly used anabolic steroid for bodybuilding purposes.

Also, the claim that MENT or its metabolites have any 'antiandrogenic action' does not appear to be substantiated in the article.

Yes, some progestagens (like Cyproterone, 'Androcur') have anti-androgenic effects. But there are also progestagens (like Trenbolone) which have a very strong (pro)androgenic effect.

So based on what evidence does the author conclude that MENT is an 'anti-androgenic progestin'? I do not see any source for this in the article. And anecdotal evidence suggests that MENT is a very potent agonist of the AR.

Never ran it before

Never had any intention to run it prior to this article, but now I sure as hell won't run it

Know a few people that ran it and had to bail because their blood pressure went through the roof. Think ill just stick to classic test

 

[Methyltst1993]

have been using MENT for the third day. It is already my third course where I have Trestolon Acetate. It is a very strong aromatizing substance. I focus on strength growth not muscle building, and this steroid is perfect for that. It is stronger than trenbolone but has about the same negative effects as tren.

@Millard please review, I know this one might have required additional editing given its appearance in web vs. editing views.

First, let's make sure we understand the dstinction between progestins and progestagenic androgens. I will refer you to:

Article on distinguishing progestins, prolactin, and progestagenic androgens (e.g., Tren, MENT, Deca) & SERM vs. AI logic [by Type-IIx]

Introduction Prolactin: Protein (peptide hormone; 227 AA, ~26 kDa) encoded by the PRL gene that primarily acts on the mammary gland to promote lactation Progesterone: Female sex steroid hormone (C21-steroid, 20-oxo steroid, 3-oxo-Delta(4)) that primarily acts to maintain pregnancy & decrease...

The distinction between trenbolone's gestagenicity vs. MENT's is that trenbolone's arises out of its triene (Δ4,9,11) structure vis-à-vis broad homology among the ligand-binding domains of the classical nuclear steroid receptors that share a common relatively low sequence identity.

In the case of trenbolone, its Δ4,9,11 double bonds result in a flattening of the steroid molecule which leads to conformation that is less hindered for AR binding. Since C-7 is sufficiently distal from C-3 and C-17, these double bonds see minimal steric or stereoelectronic interfere with the important interactions between the AR and the carbonyl- and hydroxyl- groups of the steroid. The combination of a 17α-side chain and conjugated Δ4,9,11-double bonds in the case of trenbolone, in the presence of hydrophobic substituents, leads to a steroid that is able to bind firmly not only to the AR and PR, but also to the MR and GR.

Conversely, in the case of MENT, its substitution of a methyl group in the 7α- position, while too serving to flatten the steroid molecule – perhaps facilely appearing as analogous to trenbolone – is distinguished from trenbolone by its:

(a) binding with considerably less potency to AR, reducing antiestrogenic and androgenic potency, and

(b) aromatizing to the most potent known estrogen as well (whereas trenbolone does not aromatize).

Since progestins increase estrogen sensitivity and combine synergistically with estrogens to cause hypertension, edema, gynecomastia, and other estrogenic & gestagenic maladies, MENT stands quite apart from trenbolone in its reduced efficacy versus trenbolone, given trenbolone's myriad practically applicable unique effects.

In summary, whereas trenbolone is a most potent nonaromatizable androgen, a member of the Δ4,9,11 steroids (trienes; e.g., trenbolone & metribolone & THG, "The Clear"), a class that possesses notable structural flexibility due to conformational mobility coupled with remarkable AR transactivation potency, MENT is by contrast a mild anabolic – (to wit, unmethylated Cheque drops which is itself used as a pure androgen without hardly a scintilla of significant anabolic effects in man). MENT combines its unremarkable anabolism with the most potent known estrogen, 17α-methylestradiol, synergistic in its harms, along with MENT's > 120% potency at the PR (progesterone receptor) versus trenbolone's.

Very welcome.

I focus on strength growth not muscle building, and this steroid is perfect for that. It is stronger than trenbolone but has about the same negative effects as tren.

Stronger in what sense? Non- muscle building? I agree, it builds breast tissue extraordinarily well indeed.

Very welcome.

In terms of increased strength and sex libido. It is a strong androgen, but whether it is stronger in the sense of anabolism, I do not dare to say that.If I compare it with Trenbolone. But that's just my impression and feeling.
