What is Oxandrolone 20 (Astera Labs)?
Astera Labs oxandrolone in 20mg tablets, 100 to a sachet. Anavar at the strength for men running a full dose, not for the low doses women use.
Also sold as Anavar, Oxandrin, Lonavar or Vasorome.
Oxandrolone is a mild oral that does not aromatise, so water retention and estrogen management are not part of the picture. It also lowers SHBG, which raises the free portion of whatever testosterone is already in your system, so it tends to make the rest of a cycle work harder rather than simply adding to it.
Oxandrolone 20 benefits
- Strength gains without the bodyweight, which is why weight-class athletes use it
- Holds onto muscle through a cut, when calories are low and training volume is high
- No aromatisation, so no water retention and no estrogen to manage
- Lowers SHBG, freeing up more of the testosterone already in your system
- 20mg tablets suit men running 40 to 60mg without splitting anything
Oxandrolone 20 dosage
- Men
- 40 to 60mg per day, which is 2 to 3 tablets
- Men, strength focus
- Up to 80mg per day
- Women
- Not this strength, see below
- Frequency
- Split into 2 doses across the day
- Half-life
- About 9 hours
- Cycle length
- Around 8 weeks, not longer as routine
Split the daily total into two doses, morning and early evening. Oxandrolone clears quickly and spreading it keeps levels steadier through the day.
This strength is wrong for women. Female dosing is 5 to 10mg a day, which would mean quartering a 20mg tablet. ANAVAMED 10 is the appropriate product there, and even that gets halved.

Who is Oxandrolone 20 for?
Men running oxandrolone at a full dose, where 20mg tablets mean two or three a day and nothing gets split. Weight-class athletes, people cutting who want to keep what they built, and anyone wanting more out of the testosterone already in their cycle.
ANAVAMED 10 is the same compound at 10mg in a 50-tablet box, which is the right product for women and for anyone wanting finer steps.
How to use Oxandrolone 20
Swallow with water, with or without food depending on how your stomach handles it. Split the daily total into two doses, morning and early evening. Keep alcohol low for the duration.
