Oxandrolone (Oxandrolone (Anavar))

Category: Hormone Replacement. Status: FDA Approved (Schedule III).

A mild oral anabolic steroid with a favorable safety profile, prescribed for muscle wasting, severe burns, and weight regain. Popular in biohacker circles for body recomposition with minimal androgenic side effects.

How it works

Binds androgen receptors with high anabolic:androgenic ratio (~10:1). Does not aromatize to estrogen. Increases nitrogen retention, protein synthesis, and phosphocreatine resynthesis while reducing SHBG.

Community reviews of Oxandrolone

Rated 4.2 out of 5 from 5 community reviews by ResearchSafe members.

  • stack_logic_lisa rated it 4/5 - Bloodwork stayed reasonable throughout: Oxandrolone delivered on its reputation. Used at a conservative dose because I value health markers over maximum gains. Still got impressive results: strength up across all lifts, muscle fullness noticeably improved, recovery between sessions dramatically better. Side effect management was key. Had my protocols dialed in before starting. Minor androgenic sides (slightly oily skin) that resolved post-cycle. No significant mood issues at my dose. Would I run again? Yes, but with the same conservative approach and mandatory bloodwork. These compounds demand respect and responsibility.
  • cycle_sage rated it 5/5 - Solid gains with manageable sides: Ran Oxandrolone for about 6 months at a moderate dose with proper support (AI, liver support, PCT planned). Strength went up noticeably by week 3-4 and body composition improved steadily. Side effects were present but manageable at the dose I ran. Some acne on shoulders, slight mood elevation (positive), and lipids shifted but stayed within an acceptable range per bloodwork. Did not push the dose and I think that made the difference. This is not something to approach without bloodwork, proper cycle support, and a real PCT plan. But used responsibly, the results are undeniable. Recovery betwe
  • loading_phase_lucy rated it 4/5 - Results matched expectations at moderate dose: Moderate dose of Oxandrolone for 4 months. Added about 8-12 lbs of lean tissue while body fat stayed stable or dropped slightly. Strength gains were progressive and consistent. Bloodwork at mid-cycle showed suppressed natural production as expected, lipids shifted but not dramatically. Liver values stayed fine. Ran proper cycle support throughout. The compound does what it says. It is not magic and it does not replace hard training and diet, but it amplifies everything you are already doing correctly. PCT brought things back to baseline within 4-6 weeks.
  • curiousandre rated it 4/5 - Better joint recovery for the clinic: My knees felt way better during long shifts at the clinic, just my own experience. Dropped 18 lbs over 12 weeks, felt leaner. Only downside was a bit of skin dryness, but mostly a win.
  • mom_honest rated it 4/5 - leaner, harder, and pretty damn noticeable: for me, the biggest change was how much tighter i looked in about 6 weeks, especially around the waist. i was training around long clinic days on the west coast and dropped about 9 lbs without feeling flat. i liked it overall, just had some mild dryness that was kinda annoying.
