What is Stanozolol 20 (Astera Labs)?
Astera Labs stanozolol in 20mg tablets, 100 to a sachet. Oral Winstrol at the strength for people already running it at 40mg a day.
Also sold as Winstrol, Winny or stanozolol.
Stanozolol is a DHT derivative that cannot aromatise, so nothing it does involves water or estrogen. What it gives is a flat, hard, vascular look and a jump in strength out of proportion to the size gained. It is 17-alpha-alkylated, which is what makes it work as a tablet and what limits how long you can run it.
Stanozolol 20 benefits
- A hard, dry, vascular look with no water at all
- Strength gains out of proportion to the bodyweight added
- Cannot aromatise, so no estrogen and no water from it
- The standard finisher for a cut, timed so the dry look arrives when body fat is already low
- 20mg tablets and 100 to a sachet, which suits the higher end of the dose range
Stanozolol 20 dosage
- Standard
- 40mg per day, which is two tablets
- Lower end
- 20mg per day, one tablet
- Run alongside
- Testosterone as the base
- Frequency
- Split into 2 doses across the day
- Half-life
- About 9 hours
- Cycle length
- 6 to 8 weeks maximum
At 40mg the split is simple: one tablet morning, one early evening. The half-life is around nine hours, so that spacing matters.
Six to eight weeks is the ceiling and the liver sets it. If you want to run 30mg, the 10mg tablets are the better buy.

Who is Stanozolol 20 for?
People who already know stanozolol suits them and run it at 20 or 40mg, where a tablet is a whole dose or half of one.
WINIMED 10 gives 10mg steps, which is what you want while still finding your dose. There is also an injectable version, which is no easier on the liver.
Before you run it. The liver is what limits every compound on this page. The 17-alpha-alkyl group is what lets the tablet survive digestion and reach your bloodstream intact, and it is the same feature that puts the liver under load. Cycle length is set by that, not by how well you tolerate it. Six to eight weeks is the ceiling for stanozolol. The second thing it is known for is joint discomfort: it dries out the joints in a way most compounds do not, and combined with the strength it adds quickly, that has caused a lot of injuries. It also pushes cholesterol the wrong way harder than most orals. It does not aromatise, so estrogen management applies to whatever you run alongside rather than to this.
Post-cycle therapy is still required. Keep alcohol low for the duration and do not run a second alkylated oral alongside it.
Bloodwork before and after is how you know where you stand. Not for anyone under 18, and not for women who are pregnant or breastfeeding.
How to use Stanozolol 20
Swallow with water, with or without food. Split the daily total into two doses, morning and early evening. Keep alcohol low for the duration.
Frequently asked questions
Why does it make my joints ache?
Stanozolol reduces the water held in and around connective tissue, which is part of how it produces the dry look. The same effect leaves joints less cushioned than they were.
It matters more than it sounds, because stanozolol also adds strength quickly. Stronger muscles pulling on drier joints is how people get hurt on this compound.
Would the injectable version be easier on my liver?
No. The liver load comes from the 17-alpha-alkyl modification built into the molecule, not from the route it takes to get into you.
Injecting bypasses the stomach, not the liver. It is the same compound, the same cycle length and the same monitoring either way. The only real difference is convenience and whether your stomach objects to tablets.
Does it aromatise?
No. Stanozolol is a DHT derivative and cannot convert to estrogen, which is why there is no water retention and no gyno risk from it.
The testosterone you run alongside it still aromatises, so estrogen management is about that rather than this.
Will it work if I am not already lean?
Not visibly. Stanozolol removes water and hardens what is already there. Under a layer of fat there is nothing for it to reveal.
That is the single most common disappointment with it. Run it at the end of a cut rather than the start.
How long should a Winstrol cycle be?
Six to eight weeks. The liver sets that limit, not tolerance.
It is usually run at the end of a longer cycle rather than as the whole thing.
