MESO-Rx Exclusive Unique characteristics of MENT

That’s fine. The subsequent article about testosterone should serve to clarify the answer to your question that depends on understanding 5a-amplification in CNS and gonadal tissues and why MENT does not and testosterone does act androgenically to support sexual function. I will make sure to include the actual definition of androgenicity since apparently it is totally misunderstood.
I don't have a question mate. Making up terms like '5a-amplification' does not make your arguments any more compelling. Yes, MENT does not convert to a more potent androgen in target tissues via 5a reductase, but neither do other steroids like Tren or Masteron. Are those also ''antiandrogens"? Of course not.

Always trying to weasel out of untenable positions with sophistry.... I will not be engaging with your posts any further.

I think you need to understand 5a-amplification and the meaning of androgen for us to have a constructive conversation. So I must demur for the time being.
 
It would be great to hear more people's personal experience with this as studies don't always apply to bodybuilders or people who live a bodybuildling lifestyle. Not to discredit them but real life experience is valuable.

Also it sounds like most of the side effects from this drug are related to high estrogen. What would happen with if lower doses were taken with appropriate estrogen management? Could it be efficient at building muscle?
It has only been 24 hours but I put out this poll (will post up the final results after 1 week) that is still interesting thus far:

I personally really enjoy ment, however I had to drop it due to gyno formation at 150mg per week. At 75 per week the strength gains were amazing, and I had no estrogen problems. Strength wise, it felt like 300 tren without the psychological problems that accompany the insomnia, increased libido sides, and digestive issues.

I was extremely watery, but sleep, libido, hunger, mood and blood pressure were all fine. I gained a fair amount of mass my last bulk, using it with a small amount of EQ and a moderate amount of test. Around 275 EQ, 600 test, 75 ment as highest dosages (I tried 150 ment but had to stop after one or two weeks). I would run it again, but not exceeding 75mg-100mg to avoid seeing my gyno get worse. The thing is, I don’t care if I look watery and bloated in a bulking phase, and other than that I had no quality of life sides, and no affect to my digestive system and so except for significantly more body hair it felt very useful for me. Just my anecdotal experience
 
@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:



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.
I should add to this as well:

(c) MENT is resistant to SHBG binding, and SHBG-androgen complexes regulate secondary sex characteristics and differential sex development (i.e., androgenicity) via binding the megalin receptor (SHBG promoter gene). [1]. [2].

Hammes et al. (2005) showed that resistance (insensitivity) to sex steroid hormones is encountered in animals lacking megalin. [2]. and it is associated with secondary sex characteristics and differential sex development. [3].

MENT's relative antiandrogenicity (per-mg) arises out of its relative PR/AR potencies and resistance to 5α-reductase. Whereas its androgenicity is maintained at high doses/concentrations, at the doses used in human trials to investigate its efficacy as a male contraceptive it is clearly ineffectual.

20 odd studies cited only 1 directly related to MENT.
I recognize you both. Are you familiar with the parable of Confucius and the tree? The analogy between destructive noise and quietly growing?

What have you built for the world recently? Anything?
 
Going to just chime in and say that I don't have the in depth knowledge to debate the science behind the arguments being made for and against MENT here, but I have ran it several times. The first time I ran it, I went all the way up to 25mg/day. To say that it isn't useful for bodybuilding purposes seems incorrect, since at this dose (and 500mg test) I absolutely blew up, and was adding 10-15lb to my compound lifts. I got stretch marks on my delts and lats. I did also experience high blood pressure and some progesterone related issues but AI, Nolvadex, and Caber along with some blood pressure meds mostly resolved those. Ultimately I'm not looking to run it again since realistically the health cost to benefit ratio isn't worth it for me as a non-professional in the space of bodybuilding or powerlifting. Also I would like to maintain my fertility and MENT, of course, is incredibly suppressive. I think at around 10mg/day though, MENT would probably do some great things with relatively little in the way of side effects. I think this ends up in the category of drugs that is classified as "definitely works, but the number of additional ancillaries required to make running it a very effective dosages ultimately worth it are too many". As my priorities shift, my opinion is that most drugs fall into this category. Test is best, the rest isn't often worth it.

100% agree. I couldn’t run up to 25mg per day, and only did 50-75mg total per week but it was one of the single best compounds I have used for strength . I added an entire plate to my incline, 155lbs to my hip thrust, 175 to my Romanian deadlift, and about 50lbs to my pull-down. Also without training conventional deadlift I added an extra 45lbs to my pull to get it closer to 700, when I did some 1rms on a whim. I certainly don’t believe a claim that it has no useful bodybuilding applications in practice. I log and take videos of lifts and when I finished my cycle I was legitimately shocked at some of the numbers. There are certainly drawbacks about the compound and maybe they aren’t worth it for some people, but it worked like nothing else for getting me strong.
 
I just tried to run it and the bloat was insane. Only 10mg a day. Dropped to 5mg and it was better, but still major water retention. I don't think I can run it without an AI unless I keep my dosage stupidly low, like 1mg a day (I've done that in the past when I was aiming for 10mg and somehow did the math wrong).

I am on 200mg test prop (ed shots), 200mg primo e, 200mg mast e, 200mg npp and 100mg tren e, plus 12.5mg of stanozolol a day. As soon as I dropped the MENT the bloat went away and I started making solid gains. I was actually getting weaker and smaller on 10mg of MENT (I don't get gyno, but I do bloat up around the waist and get weaker when my e2 is high). I'll try to reintroduce it at 1mg a day tonight, just because I want to use it up.

I'm going to replace NPP 150mg/week solo for Trest E solo at 10mg/WEEK. Too low? I know but supposedly everyone is running into estrogen problems because everyone is using like 10x the dose used in studies for hormone replacement. Look at the comments in this very post. 10mg/day=70mg/week is already too much for some and causes them bloat. People lower it to <5mg/day and the bloat goes away.
In HRT context studies were using 1mg/day and even less!
Yea this stuff is extremely potent.

Don't run it solo, you need testosterone for a bunch of physiological functions.

I'm aware and willing to take the risk for this experiment. Trestolone supposedly can replace all testosterone biofunctions at a much lower dose. I belie e it was initially created as a contraceptive and later studied for that and also hormonal replacement at 400-700mcg/day with pellets. If it has 4-6 times the androgenicity of testosterone it means it's potent enough to replace DHT when binding to the ARs. Also converts intro 7a-methyl-estradiol, I understand some say it has higher toxicity than bio estradiol but still it has great affinity to the ERs and could probably replace its functions.
 
On my next blast, I plan on running 5mg or 10mg a day and running an additional 100 or 200mg of primo alongside it for the AI effect.
 
MENT is a compound that I thoroughly enjoy but have to accept it for what it is and take extra precautions.

I will not run it without EQ in the stack because it aromatizes so fast and so strongly. I've read somewhere in the past that it's a more potent binding of the receptors and that's why it seems like e2 sides x100. or something like that. Can't remember the study or verbiage so I don't want to misquote it. But it sure as hell fills me up what seems like overnight. MENT is the main compound that I can use and people will immediately start to ask me if I'm on something because I look so full.

Most practical stack - Test / EQ / MENT

Best "feeling" stack for me - Test / Mast / Ment (I say feeling because mast helps me skip over the mental part of estrogenic sides but my levels still go wild and i'm at risk of gyno)

I can handle up to 15mg a day but at 20+ it's not worth it. Usually run for 8 weeks max.

Sides - any estrogen sides to a new level if you aren't cautious, potential BP increases for many. I take telmisartan 20mg a day, hit my cardio, and I'm fine.
