Anavar is the well-known name for oxandrolone, one of the most studied oral compounds in performance research and prized for its favourable anabolic-to-androgenic profile. This 25 mg presentation is a higher per-tablet strength suited to standard research protocols. Supplied as lab-tested oral tablets for research use only.
Oxandrolone is a synthetic dihydrotestosterone (DHT) derivative: an oxygen atom replaces the carbon-2 position in its A-ring, which raises anabolic activity while keeping androgenic activity comparatively low. Because it is a DHT derivative it cannot aromatise to estrogen — meaning no estrogenic water retention and no estrogen-driven gynecomastia in study models. That “dry” profile is what distinguishes it from wetter compounds like Anadrol 50, and it is one reason estrogen-management tools such as Arimidex (Anastrozole) are usually unnecessary alongside it.
Oxandrolone has a short half-life of roughly 9–10 hours. In research settings this short window means protocols often split the daily amount into two doses to keep blood concentrations stable across the day rather than a single dose.
Although oxandrolone has a “mild” reputation, it is 17α-alkylated and can be hepatotoxic — elevated ALT/AST are reported, especially at higher strengths or longer durations, so research protocols keep cycles short (≈6–8 weeks) with liver support. It also tends to lower HDL and raise LDL cholesterol, and can suppress natural testosterone, so post-cycle support is studied afterward. Reported effects are dose-dependent and are research observations only.
The 25 mg tablet suits standard performance-research protocols where a full per-day amount is reached with fewer tablets. For lower-dose, precision, or female-model research where smaller increments matter, our Anavar 10 mg presentation is the better fit. Oxandrolone is frequently studied in cutting/hardening contexts and stacked in research alongside Testosterone Enanthate or Winstrol.

KGEAR U.S supplies research-grade oxandrolone with discreet, tracked US shipping and crypto checkout. All products are sold strictly for research use only.
Only the per-tablet strength. The 25 mg suits standard protocols; the Anavar 10 mg allows finer, lower-dose increments.
No — as a DHT derivative it does not aromatise, so there is no estrogenic water retention or estrogen-driven gyno in study models.
Roughly 9–10 hours, which is why research protocols often split the daily amount.
It is 17α-alkylated and can be hepatotoxic at higher strengths/longer use despite its mild reputation; short cycles with liver support are standard in research.
Yes — HPLC verified, batch COA available on request; see our third-party HPLC lab reports.
