Buy Oxymetholone by Zyvex at XSteroids. This card is the 50 mg Anadrol tablet, 100 to a pack, supplied by the brand as a single strength product. The text below explains what the tablet contains, how a non aromatising steroid still produces water and nipple sensitivity, what a short block feels like, how a 50 mg tablet is dosed, which compounds sit beside it, how recovery works and which measurements decide when to stop.
In the United States and across most of Europe oxymetholone sits on the controlled substances list, and its pharmaceutical form is a prescription medicine reserved for particular anaemias. The tablets on this page carry a Zyvex label and are sold for bodybuilding and laboratory reference, so every quantity quoted below comes from published study and from community practice rather than from a treatment plan.
Oxymetholone is an oral anabolic steroid that doctors have prescribed since the early 1960s, most familiar commercially under the names Anadrol and Anapolon. In chemical terms it arrives already reduced at the 5-alpha position, so it behaves like a finished dihydrotestosterone-type molecule and neither aromatase nor 5-alpha reductase accepts it as a substrate.
The Zyvex pack holds 100 tablets, each printed at 50 mg, the strength this compound is traditionally sold at. There is nothing elaborate in the formulation: it is an ordinary alkylated oral whose whole story revolves around fluid, blood pressure and the short window it can be run for. No laboratory assay of this particular batch has been published, which leaves the printed number as a label claim.
The drug docks onto the androgen receptor, ramps up protein synthesis and has a notably powerful effect on red cell production, which is why it ever received approval for anaemia. Haemoglobin and haematocrit climb, oxygen transport improves, and people frequently notice endurance and recovery improving before any change in size becomes visible.
Fluid retention is the puzzle at the centre of this compound. It cannot be aromatised at all, yet reports link it to heavier subcutaneous swelling and more breast tenderness than nearly any other product in circulation. The explanation most often given is that the molecule itself engages the estrogen receptor, or acts through progesterone signalling, instead of being converted into estradiol. An aromatase inhibitor therefore does nothing for the swelling. That is the reason blocks are kept brief, monitored closely and never stacked with other wet compounds.
The scale moves within days, sometimes in the very first week, and most of that initial jump is fluid and stored glycogen rather than new tissue. Top-end strength climbs quickly, hunger tends to drop while the daily amount is high, and the physique looks fuller rather than sharper. Four weeks is long enough to see everything the compound does.
Blood pressure usually climbs further here than with any other oral tablet, morning weight can swing by a kilogram or more, and part of the strength gained disappears once the fluid drains away after the block ends. Anyone hoping to keep the size normally pairs the tablet with a slower injectable that carries on building after the oral has stopped.
Published reference figures begin at 25 to 50 mg a day, so half a tablet or one whole tablet, and long term users occasionally work up to 100 mg. Beyond that mark the fluid, pressure and liver strain increase faster than any benefit, which is why few go higher. Elimination takes about eight to nine hours, so where practical the daily amount is divided in two.
Cutting the 50 mg tablet in two gives a 25 mg dose in the morning and the same again in the evening, which smooths the peak and keeps the level more even. Four weeks is the typical block, with six as the absolute limit, since an alkylated oral and a pressure effect that builds with time are a poor combination.
Blood pressure, morning body weight, haematocrit, liver enzymes and any nipple soreness are the numbers and symptoms that matter. A systolic reading that stays above baseline for several days is the most common reason to cut a block short.
A testosterone base accompanies this tablet in nearly every plan, since the compound shuts down the body's own production while contributing no testosterone of its own. Testosterone Esters from Zyvex are the customary foundation, and Sustanon 250 delivers the same support with a single injection each week.
When size is the goal the tablet is paired with Nandrolone Esters from Zyvex, which continue working after the oral is stopped and ease the joints along the way. Boldenone Undecylenate is the slower road for anyone who prefers quality over the quickest movement on the scale. An aromatase inhibitor such as Arimidex will not touch the swelling produced by this compound, although the base may call for one, and Nolvadex belongs after the block rather than during it.
With an elimination half-life of just eight to nine hours the drug leaves the system in a couple of days, so a SERM can be introduced as soon as any injectable partner has washed out. Tamoxifen or clomiphene for four weeks is the customary window, extended to six after a longer or heavier block.
Both Nolvadex (tamoxifen) and Clomid (clomiphene) sit in the Zyvex line-up. Body weight should be expected to drop as fluid is shed, and that drop is not muscle loss: over a four week block only a small share of the total weight change on the scale is real tissue.
Reported problems include fluid build-up with higher blood pressure, headaches caused by that pressure, tender nipples or gynecomastia even when estradiol reads normally, a poor appetite, reduced HDL cholesterol and raised liver enzymes. The body's own testosterone output is shut down, and over a longer block haematocrit can rise far enough to make the blood thicker.
The severe end of the list covers dangerous hypertension, liver damage and, rarely, hepatic complications after prolonged use, which is precisely the reason this compound is kept to short blocks instead of serving as a base. In sport it is prohibited under WADA class S1 at every moment, in and out of competition, and this listing exists purely for research. Research use only.
Leave the carton sealed in a dry spot at ordinary room temperature, clear of sunlight, radiators and damp rooms such as bathrooms, and put it somewhere children and animals cannot get to it. Tablets of this kind need no refrigerator and should never see a freezer. Read the batch number and the expiry date before starting, and throw away anything cracked, faded or stuck into a block.
The tablet appears in the Zyvex brand catalog at XSteroids, where the test base, the slower injectables and the SERM a short block calls for all sit on nearby shelves, so one order supplies the whole plan. Payments are handled over an encrypted connection. Domestic orders in the US normally arrive within three to six days, and international deliveries take twelve to twenty-six days. The cards below name the usual partners.
The fluid does not come from conversion to estrogen, because oxymetholone is not a substrate for aromatase. It appears to come from direct activity at the estrogen receptor or from progestogenic action, which is why an aromatase inhibitor does not remove it and why the compound is run in short blocks.
It is a full reference dose. Users who want a softer start split the tablet into two 25 mg portions, one in the morning and one in the evening, which suits the eight to nine hour half-life and reduces the size of each peak without changing the daily total.
Four weeks is typical and six is the ceiling. The limit comes from blood pressure, water retention and liver enzymes rather than from how the gains feel, and longer blocks are associated with rising haematocrit and worse lipid values.
Because a large share of the early gain was water and glycogen rather than muscle tissue. Once the drug clears, that fluid leaves over one or two weeks, and the scale falls accordingly. Keeping a slower injectable running through the period is the usual way to hold onto the tissue.
It does, and strongly. Oxymetholone was approved precisely for its effect on erythropoiesis, so haemoglobin and haematocrit rise during a block. That improves endurance for some users, but it also thickens the blood, which is one more reason to keep the course short and to monitor blood pressure.
A testosterone base keeps the cycle functional, because the oral suppresses natural production and supplies no testosterone. An aromatase inhibitor may still be required for the base, but it will not address the water from oxymetholone itself. Recovery afterwards uses a SERM.
