Oxandrolone
A DHT-derived anabolic steroid that promotes nitrogen retention and protein synthesis in muscle tissue.
Medically reviewed by Dr. Jonathan Snipes, MD. Last reviewed May 6, 2026.What It Is
Oxandrolone (Anavar) is a mild oral anabolic steroid with a long history of medical use for muscle wasting, surgical recovery, and burn patients.
How It Works
It increases nitrogen retention in muscles, promotes protein synthesis, and enhances red blood cell production. Supporting lean muscle development with minimal water retention.
Who It's For
Those recovering from surgery, illness, or significant muscle loss. Also prescribed for body composition optimization under strict provider supervision.
Who Should Avoid It
Not for those with liver disease, prostate issues, or cardiovascular concerns. Requires regular lab monitoring. Not for pregnant women.

Common questions about Oxandrolone
- What is oxandrolone (Anavar)?
- Oxandrolone, sold under the brand name Anavar, is a synthetic anabolic-androgenic steroid FDA-approved for the treatment of weight loss after surgery, infection, severe trauma, certain forms of osteoporosis, and to offset protein catabolism caused by long-term corticosteroid use. It is a Schedule III controlled substance under the DEA controlled substances schedule.
- Is oxandrolone legal and how is it scheduled?
- Oxandrolone is a federal Schedule III controlled substance. It is legal to prescribe under a DEA-licensed provider in states where the prescriber is registered. PeptideRx prescribes oxandrolone only in states where state law and provider DEA registration permit, and only after additional clinical screening that goes beyond a standard peptide intake. Possession or distribution outside of a valid prescription is a federal crime.
- Who is a candidate for oxandrolone via PeptideRx?
- Candidates are adult patients with a documented FDA-approved indication (post-surgical weight loss, severe trauma recovery, certain forms of osteoporosis, corticosteroid-induced muscle wasting) or a clinically defensible off-label indication, who pass DEA-state licensure checks, complete enhanced intake including baseline labs, and provide informed consent for the controlled-substance pathway. Recreational requests for muscle-building purposes are typically declined.
- How is oxandrolone dosed?
- FDA-approved adult doses range from 2.5 to 20 mg per day in divided doses (typically 2 to 4 doses per day). Total daily dose is set by the provider based on indication, body weight, lab values, and concurrent medications. Most therapeutic protocols run 2 to 4 weeks at a time with mandatory follow-up labs before continuation.
- What labs and follow-up are required on oxandrolone?
- Baseline and follow-up labs typically include complete blood count, comprehensive metabolic panel (with attention to liver enzymes), lipid panel, and total testosterone. Oxandrolone can elevate liver enzymes, lower HDL, and suppress endogenous testosterone production at doses above 20 mg per day, so follow-up labs at 4 to 6 week intervals are required while on therapy.
