What is Chlorodehydromethyltestosterone 20 (Astera Labs)?
Astera Labs turinabol in 20mg tablets, 100 to a sachet. Steady lean gains with no water, and the longest detection window of anything in the catalogue.
Also sold as Tbol, Oral Turinabol, OT or chlorodehydromethyltestosterone.
Turinabol is methandienone with a chlorine atom added at the fourth carbon. That change removes aromatisation entirely, which is why it produces lean, dry gains with no water where its parent compound produces the opposite. It is still 17-alpha-alkylated. It is slower and milder than almost anything else here, and that is the point of it rather than a shortcoming.
Turinabol 20 benefits
- Steady, lean gains with no water retention at all
- Cannot aromatise, so no estrogen and no gyno risk from it
- Noticeably milder side effect profile than the other alkylated orals
- Strength climbs steadily rather than spiking and dropping
- Well suited to a lean bulk or a recomposition rather than a hard cut or a hard bulk
- 20mg tablets suit the common 40mg dose as exactly two a day
Turinabol 20 dosage
- Standard
- 40mg per day, which is two tablets
- Lower end
- 20mg per day, one tablet
- Higher end
- 60mg per day, experienced only
- Frequency
- Split into 2 doses across the day
- Half-life
- About 16 hours
- Cycle length
- 6 to 8 weeks
At 40mg the split is simple: one tablet morning, one early evening.
Give it six weeks before judging it. Turinabol works slowly, and a four week run shows very little. That is the compound behaving normally rather than underdosed product.

Who is Turinabol 20 for?
People who already know turinabol suits them and run it at 20 or 40mg, where a tablet is a whole dose or half of one.
It is the wrong choice for anyone tested in sport, at any level. TURIMED 10 gives 10mg steps, which is what you want while still finding your dose.
Before you run it. The liver is what limits how long you run this. 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. Six to eight weeks is the ceiling for turinabol.
The detection window is the thing to know about this compound specifically. Its long-term metabolites have been identified in testing many months after the last tablet, in some cases beyond a year, which is why it turns up repeatedly in retrospective sample re-analysis. If you compete in a tested sport, this is one of the worst possible choices. It does not aromatise, so estrogen management applies to what you run alongside. It still suppresses your own production, so
post-cycle therapy is 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 Turinabol 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
How long does turinabol stay detectable?
Far longer than almost anything else. Its long-term metabolites have been detected many months after the final tablet, and in some documented cases beyond a year.
This is not a theoretical concern. Turinabol is the compound that reappeared in a great many retrospective re-analyses of stored samples. If you are tested at any level, choose something else.
Is turinabol just a milder Dianabol?
Structurally it is Dianabol with a chlorine atom added, but the two behave nothing alike. That single change removes aromatisation completely.
Dianabol is fast, wet and heavy on estrogen. Turinabol is slow, dry and produces no water at all. The gains are smaller and far more of them stay.
How much will I actually gain?
Less than you would on Dianabol or Anadrol, and that is expected rather than a failure. Turinabol produces steady lean tissue over the course of a run instead of fast weight in the first fortnight.
The trade is that almost all of it stays, because none of it was water. Judge it at week six, not week two.
Does it aromatise?
No. The chlorine at the fourth carbon blocks conversion to estrogen entirely, so there is no water retention and no gyno risk from turinabol itself.
The testosterone you run alongside it still aromatises, so estrogen management is about that rather than this.
How long should a turinabol cycle be?
Six to eight weeks. The liver sets that ceiling, the same as with any alkylated oral.
Because it works slowly, running it for only four weeks tends to show very little. Six is a sensible minimum for this compound specifically.
