Buy Trestolone MENT by Xeno Labs at XSteroids. Trestolone, known as MENT, is short for 7alpha-methyl-19-nortestosterone, an experimental androgen first studied as a male hormonal contraceptive and as a replacement therapy candidate. Xeno supplies it as a 10 ml multi-dose vial. This page covers what the molecule is, how it works, what to expect, how it is dosed, what stacks with it, how recovery is planned and what the risks are.
MENT is one of the most potent injectables in the Xeno range, and a small weekly amount goes a long way. The order arrives as a sealed 10 ml multi-dose vial, and its natural partner, a testosterone base, sits in the same catalogue. The vial carries a Xeno Labs label and is catalogued as a research and bodybuilding item, so the text below serves as reference material rather than a personal protocol to copy.
What Xeno Trestolone MENT Is and What You Are Buying
Trestolone MENT is 7alpha-methyl-19-nortestosterone, a steroid that sits between the anabolic androgens and the progestogens in how it behaves. The 7-methyl group protects the molecule from the enzyme that normally deactivates testosterone, which is part of why it stays active for longer in tissue and why a small dose goes a long way.
Xeno lists the product as a 10 ml multi-dose injectable. Nothing in print confirms the potency of this vial and no filler list comes with it, so the page stays with the pharmacology of the molecule and makes no promise about a measured strength for a particular batch.
How Trestolone MENT Works
MENT binds the androgen receptor and drives protein synthesis and nitrogen retention like any strong anabolic, but it also has a pronounced progestogenic character and a powerful effect on the pituitary. Even at low concentrations it suppresses the release of luteinising hormone and follicle stimulating hormone, which stops sperm production, and that is precisely the mechanism the contraceptive researchers were studying.
One structural detail separates it from testosterone. MENT is not a substrate for 5alpha-reductase, so it is not amplified or inactivated in skin, hair follicles and prostate the way testosterone and DHT are. Its estrogenic route is also its own: a 7alpha-methyl estradiol metabolite is formed, so the estrogen picture is not identical to a testosterone cycle even though it shares some of the same water and sensitivity questions.
What to Expect from Trestolone MENT
Users describe rapid fullness and strength, a strong effect on libido, and a shut down natural axis that arrives fast because the pituitary signal falls so hard. Because oral bioavailability is poor and the plain molecule has a short half-life, the practical format for a run is an injectable ester with frequent administration.
Expect the cycle to behave unlike nandrolone or testosterone in the estrogen department, and expect suppression to be complete rather than partial. There is no fixed clinical schedule to copy, so dosing rests on community practice and on measurement, and the water and blood pressure effects deserve attention from the first week.
Trestolone MENT Dosing Practice
Community figures sit in the low tens of milligrams per day rather than in the hundreds per week, because the compound is potent per milligram and its half-life is short. That means frequent small injections rather than one weekly shot, and it means the first two weeks are used to judge tolerance rather than to chase a number.
Injection rhythm
Because the ester used determines how long the hormone lasts, injections are spaced to keep a level rather than to create a peak. Daily or every-other-day shots are the common pattern. Rotating sites matters, and the volume per site is kept small because the compound is not known for gentle injections.
Markers to follow
Blood pressure, estradiol, prolactin and the lipid panel are the numbers that matter. Because MENT shuts down gonadotropins hard, testosterone will read low without a base, and only the base keeps normal function running through the cycle. Any dose change should follow a measurement, not a mood.
Stacking Trestolone MENT With Testosterone
A base is essential. Xeno Labs Testosterone Esters are offered as propionate, cypionate and enanthate, letting the base be matched to the injection rhythm. Skip it and the cycle runs on almost no testosterone while the side effect profile grows worse.
MENT is usually run alone beside that base rather than with a second strong androgen, because the suppression and the water effects stack quickly. If a second compound is used, a mild classic such as Primobolan 100 (methenolone enanthate) keeps the profile predictable, and Arimidex (anastrozole) is kept available for the estrogen side when a reading justifies it.
PCT After a Trestolone MENT Cycle
Recovery is not optional, because MENT stops the gonadotropin signal quickly and completely. Once the ester has cleared, a SERM is used to restart the axis, and the process normally takes four to six weeks. The stronger the suppression during the cycle, the more slowly the numbers come back.
Two SERMs are stocked in the Xeno range, Tamox (tamoxifen) and Clomiphene, and either can carry the restart. Nothing suppressive belongs in the recovery window, and the first blood test after the cycle should be taken only once the ester has fully cleared.
Trestolone MENT Side Effects and Precautions
The reported effects follow from the profile: heavy suppression of natural testosterone, water retention and blood pressure elevation in many users, gynecomastia through the estrogenic pathway, and a strong effect on libido in both directions. Insomnia and mood changes are also described.
Trestolone is classed as a controlled anabolic in the United States and sits under the WADA S1 class, which bans it in sport at all times. Almost all of what is known comes from a discontinued development programme and from user reports, so the long term safety margin is genuinely unknown. Research use only.
Two features separate it from the older 19-nor compounds. It is aromatisable, so estrogenic effects can appear even without a testosterone base in the stack, and its ester clears in days rather than weeks, which makes both the effects and the problems faster to arrive and faster to leave.
Storing the Trestolone Vial
Leave the vial standing upright and sealed at room temperature, somewhere dry, out of direct light and clear of damp rooms. An oil-based injectable is never refrigerated and never frozen. Check the batch number and expiry date ahead of the first draw, and reject a vial whose solution has gone cloudy or discoloured or that carries visible particles.

Frequently Asked Questions
What exactly is MENT on the Xeno trestolone card?
MENT is trestolone, chemically 7alpha-methyl-19-nortestosterone. It is a research androgen with strong progestogenic activity that was studied as a male contraceptive and as a replacement therapy candidate. Xeno supplies it as a 10 ml multi-dose injectable vial at the strength printed on the label, and users describe a fast, powerful response with quick suppression of the natural axis.
How does trestolone shut down the natural axis?
It suppresses luteinising hormone and follicle stimulating hormone very strongly even at low concentrations, which stops the testicular signal and sperm production. That is the same mechanism the contraceptive researchers wanted. The practical consequence for a cycle is that natural testosterone falls to near zero and a base compound becomes necessary.
Does MENT convert to estrogen?
It takes a different estrogenic route rather than the aromatase path testosterone uses. A 7alpha-methyl estradiol metabolite has been described, so estrogenic effects such as water retention and nipple sensitivity can still appear even though the profile is not identical to a testosterone cycle. Estradiol and prolactin readings are the way to see what is happening.
How much MENT is used per week?
Community dosing is measured in the low tens of milligrams per day rather than hundreds per week, because the compound is potent and clears fast. That means frequent small injections instead of one weekly shot. There is no fixed published protocol, so the dose should be judged from blood pressure and blood work rather than from other users.
Is MENT a substitute for testosterone?
No. Trestolone can maintain muscle and libido in a cycle, but it suppresses natural testosterone and does not replace every function that testosterone performs. A base testosterone ester is still the standard partner, and running MENT without one leaves the body with almost no testosterone at all.
Why was trestolone never brought to market?
It was developed as a male hormonal contraceptive and as an androgen for replacement therapy, and the research stopped before a formal dosing schedule was settled. Community logs and published pharmacology are therefore the practical reference, and the long term record is genuinely thin. That is why everything here is a research reference rather than medical guidance. Research use only.
