Zyvex Pharmaceuticals Anavar is oxandrolone in two tablet strengths, 10 mg and 50 mg, on a single page. Buy anavar here if you want the mildest of the common oral anabolics in one pack, and pick the strength that matches the smallest practical tablet rather than the largest. The fact file for this compound describes it as a DHT-derived, 17-alpha-alkylated oral with a weak androgenic profile and preserved anabolic activity, a half-life of about nine hours and no aromatisation, so it does not cause water retention.
Oxandrolone is a modified DHT molecule that survives the first pass through the liver because of its 17-alpha-alkyl group, which is what makes it orally active and also what makes it hepatically stressful. A nine hour half-life means the tablet is taken more than once a day in most community protocols, and the absence of aromatisation means no estrogenic water retention and no gynecomastia pathway. What it does not avoid is suppression: the checked file notes that shutdown becomes noticeable above 20 mg per day, which is why a run is usually closed with a restart on Clomid or Nolvadex.
The two packs hold the same molecule; the table shows what changes between the strengths.
| Formulation | Strength | Half-Life | Liver Load | Typical Use |
|---|---|---|---|---|
| Anavar 10 mg | 10 mg per tablet | about 9 h | Moderate | Gradual titration in 10 mg steps |
| Anavar 50 mg | 50 mg per tablet | about 9 h | Moderate | Fewer tablets per day at a fixed total |
Strength rises before scale does, the look gets drier rather than bigger, lipids shift with HDL down and LDL up, and liver enzymes may move slightly because the compound is 17-alpha-alkylated. Hepatic strain is lower than with stanozolol or superdrol, but the file is clear that it is not zero. Detection is another variable that has nothing to do with the half-life: epi-oxandrolone shows in urine for about seven days, while reviews stretch the window towards three or four weeks. For a different oral route, see the Zyvex Dianabol page, and for a base to pair it with, the Zyvex Testosterone esters.
Each batch is produced under GMP conditions and checked by HPLC, with the Certificate of Analysis kept for the lot. Keep the tablets in the sealed pack, away from heat and light. Purchase oxandrolone here as research material; it is not licensed for performance use.

Before you ask
It is oxandrolone, a DHT-derived oral anabolic with a 17-alpha-alkyl group that lets it survive the first pass through the liver. The fact file describes a weak androgenic profile with preserved anabolic activity, a half-life of about nine hours and no aromatisation, so there is no water retention. This page carries two strengths, 10 mg and 50 mg, of the same molecule.
The two packs hold the same oxandrolone, so the decision is arithmetic and comfort rather than potency. The 10 mg tablet allows gradual steps and is easier to split across the day for a nine hour half-life, while the 50 mg tablet means fewer units for a fixed daily total. Nothing in the checked sources shows a difference in effect between the strengths beyond how the count works out.
The oral half-life is about nine hours, which is why the tablets are taken more than once a day in community protocols. Liver toxicity is rated moderate, lower than stanozolol or superdrol but not zero, because the 17-alpha-alkyl group that makes the drug orally active is the same feature that stresses the liver. Raised liver enzymes are a possibility rather than a certainty.
The file lists the practical ones: suppression of natural production that becomes noticeable above 20 mg per day, HDL falling and LDL rising, and possible mild elevation of liver enzymes. Because the compound does not aromatise there is no water retention and no estrogenic gynecomastia pathway, which is why it has a reputation for being mild. Mild is never the same as free.
The checked file records the metabolite epi-oxandrolone in urine for about seven days, while review articles give a window of up to three to four weeks. That spread is the honest range rather than a single number, and it is measured in weeks, not in the nine hour half-life. Anabolic agents are prohibited in sport, so a tested athlete should treat any of those figures as a risk rather than a schedule.
Both strengths are listed on this page, with the variant chosen in the selector above. At the last check the 10 mg variant was listed at 64.00 USD and both strengths were out of stock, and international shipping is listed at 50.00 USD with a four to ten day transit window.
