Buy Ortrexyl 250 mcg by Kalpa Pharmaceuticals at XSteroids. Ortrexyl is methyltrienolone, the compound also catalogued as metribolone and known informally as oral tren, supplied by Kalpa as 250 microgram tablets in packs of one hundred. This page sets out what is inside the box, why the dose is measured in micrograms rather than milligrams, how the molecule behaves at the receptor, how a run is planned and stopped, and why the liver is the ceiling here.
Methyltrienolone never reached the pharmacy shelf. Early trials found it extraordinarily potent and equally hard on the liver, so development was halted, and the compound survives only as a laboratory reference standard. The pack sold here is a branded research item, not a medicine. All microgram values are reference figures from published work, not a protocol, and nothing on the page is medical advice.
Inside the pack sit one hundred very small tablets, and the strength stated on each is 250 micrograms of methyltrienolone. That is a quarter of a milligram, so four tablets together reach a single milligram. The tiny unit is forced by the drug itself, because the active amount is so small that an ordinary milligram tablet could not be worked with safely.
Kalpa states the strength and the tablet count on the carton. No external laboratory has published a result for this batch, and no list of inactive ingredients is shown, so the page repeats only what the printed label carries. Buyers should also understand that this is among the least forgiving products in the oral range and is not a starting compound of any kind.
The molecule is a nandrolone derivative, alkylated at carbon seventeen and carrying an extra double bond, which makes it both orally active and exceptionally tenacious at the androgen receptor. Laboratory binding work places its receptor affinity above that of testosterone, which is why its active amount is measured in micrograms while most orals are measured in milligrams.
Selectivity is absent. The compound also latches onto the progesterone receptor and has almost no affinity for sex hormone binding globulin, so a very large share circulates unbound. The 17-alpha-methyl group that survives the first pass is likewise the source of the hepatic problem: enzyme load rises with dose and with duration, and no form of the drug escapes that. Enormous potency with no safety margin is exactly why the research world keeps it as a reference ligand rather than a therapy.
The response is abrupt rather than gradual. Users report strength climbing and a tight, dry look within days, with none of the water an aromatising oral brings, since methyltrienolone does not become estrogen. The unwanted effects arrive at the same speed, which is why blocks are counted in days rather than months.
There is also no product-specific data. The receptor figures above come from binding studies of the raw compound, not from any trial of Kalpa Ortrexyl. That is the honest position: thoroughly characterised in the laboratory, essentially uncharacterised as a consumer product, and dosed by users on the strength of published work alone.
No clinical dose exists to quote, because the drug never entered the clinic. Research and bodybuilding guides speak of daily amounts from 250 to 1000 micrograms, one to four of these tablets, paired with a very brief block. What follows describes what the literature and user guides report, not what any reader should attempt.
Receptor affinity explains it. A molecule that grips the androgen receptor more tightly than testosterone needs only a fraction of a milligram to produce a strong signal. Going beyond the low end of the range adds liver strain faster than it adds result, which is why users describe the useful window as narrow and unforgiving.
Yellowing of the eyes or skin, dark urine, discomfort on the right side of the abdomen and unexplained fatigue point to hepatic strain and call for immediate stopping and medical review. On the hormonal side, head pressure, climbing blood pressure and a shut-down feeling send the same message: the block is over, whatever the plan said.
Because the compound is so severe, plans that include it keep everything else plain. A short-ester testosterone base such as Testoxyl keeps the androgen the body has stopped making flowing, and injectable trenbolone, the family behind Trenboxyl and Trinaxyl 150, is occasionally used as the slower partner.
Adding further strong orals is where such plans fail. A second hepatotoxic tablet, for example Haloxyl (fluoxymesterone), multiplies liver strain rather than outcome. When a stack contains an aromatising compound and estrogen control is needed, Arimixyl (anastrozole) is the tool, though it does nothing about the toxicity concerns that define this drug.
The block is short and the compound clears fast, so recovery can begin soon after the last tablet, yet the suppression it causes is deep and often abrupt. Nolvaxyl (tamoxifen) is the usual first choice, holding the estrogen receptor at the pituitary so production can restart, with Clomixyl (clomiphene) as the alternative working on the same receptor group.
Recovery here is not only endocrine. Liver enzymes need time to fall after any 17-alpha-methylated oral, so both the enzymes and the axis should settle before another cycle is considered. An aromatase inhibitor plays no part in this window at all.
Liver injury dominates the documented profile and is the reason the drug was abandoned. Beyond that, users report the usual androgen set: acne, faster hair growth, aggression, raised libido and, for some, a lower voice. Blood pressure and heart rate may climb, and natural testosterone output is efficiently suppressed while tablets are being taken.
Methyltrienolone is a controlled substance in many jurisdictions and is named on the WADA S1 anabolic agents schedule, which bans it in sport throughout the year. What is offered here is a research product, and its risks are a step above those of an ordinary oral. Research use only.
Keep the package shut and dry at room temperature, out of sunlight and away from children and humid rooms. Cold storage is unnecessary and freezing is wrong. Note the batch code and expiry as soon as the box is opened, leave tablets in their pockets until needed, and throw out any that are chipped, faded or stuck to a neighbour.
Ortrexyl is one of the specialist orals carried in the Kalpa Pharmaceuticals brand catalog on XSteroids, placed alongside the testosterone bases, the injectable trenbolone range and the full recovery shelf, so an advanced plan can be sourced from one brand. Checkout is encrypted. Parcels for United States addresses usually land in three to six days, and overseas orders take twelve to twenty-six. The cards linked below are the ones normally read next to it.
Ortrexyl is Kalpa Pharmaceuticals methyltrienolone, sold as 250 microgram tablets in packs of one hundred. Methyltrienolone, also called metribolone, is a 17-alpha-alkylated oral anabolic steroid with very high androgen receptor affinity. It is a specialist oral that experienced users keep for short, tightly measured blocks. Kalpa prints the strength and the count; no independent assay of this pack exists.
Because the molecule binds the androgen receptor more tightly than testosterone does. That potency means only a tiny amount is needed for a large effect, so the tablet is a fraction of a milligram rather than a whole one. A milligram strength would leave no room to fine-tune, and even the microgram doses carry a serious liver load.
Guides describe very short runs, measured in a small number of weeks at most, and many experienced users treat it as a compound to avoid entirely. The limit is the liver, not patience: a 17-alpha-methylated oral of this potency raises hepatic enzymes fast, and extending the same dose compounds the risk rather than improving the result.
Yes. Methyltrienolone is a synthetic anabolic androgenic steroid, specifically a 17-alpha-alkylated derivative of nandrolone. It is not a peptide, not a stimulant and not a fat burner. Its classification in law and in sport follows from that identity, which is why it sits on the WADA S1 anabolic agents list and is controlled in many markets.
Yes, and strongly. Any effective androgen suppresses the pituitary signal that drives testicular testosterone production, and a compound this potent does so efficiently even over a short run. That is why recovery planning with a SERM is standard after it, and why a cycle is not continued indefinitely on the assumption that a small daily dose is harmless.
Keep the pack sealed and dry at room temperature, clear of direct sunlight and away from damp spaces such as a bathroom. The tablets need no refrigeration and should never be frozen. Record the batch number and expiry on arrival, leave each tablet in its blister, and throw away anything cracked, discoloured or fused together.
