Turinabol is Xeno Laboratories' 4-chlorodehydromethyltestosterone, an oral tablet better known by its nickname Tbol. Chemically it is methandienone with a chlorine atom added at the four position, and that single change is the whole point: it blocks the aromatase enzyme, so the bloat and the watery weight that define Dianabol are absent while the anabolic action remains.
The compromise shows up on the other side of the ledger. It is still a methylated oral, so the liver carries the cost, and the gains it produces are slow and unspectacular by comparison with its famous cousin.
Product Overview
4-Chlorodehydromethyltestosterone is a 17-alpha-alkylated oral anabolic derived from methandienone. Because the chlorine substitution prevents conversion to estrogen, the compound produces neither fluid retention nor estrogenic breast changes, and the appearance it supports is lean and dry. Androgenic activity is lower than that of most orals, which is why it has a longer history of use by women than the stronger members of the class, though virilization remains possible and the material used here does not present a low dose as safe.
The reference half-life sits around sixteen hours with the source marking that figure as needing confirmation, so one or two intakes a day are enough to keep a level. Effects arrive gradually: strength first, usually within one to two weeks, then a dry, quality gain in muscle across weeks three to four. Nothing about it is dramatic, and users who expect an oral to deliver in a fortnight will be disappointed.
The pairing that makes most sense is a low dose of a testosterone ester to keep the androgen background intact, since the oral suppresses natural production without supplying anything that aromatizes. It is also commonly stacked with Anavar for a dry recomposition, and compared constantly with Dbol 20, which is the wetter and faster alternative for the same shelf.
Dosage Protocol
The material consulted places the working range between twenty and sixty milligrams a day, with nothing above that described. The block runs six to eight weeks, which is the usual ceiling for a methylated oral.
| Beginner | 20-30 mg a day for 6-8 weeks; the bottom of the range still produces a dry, gradual gain |
| Intermediate | 30-40 mg a day for 6-8 weeks, divided into two intakes across the day |
| Advanced | 40-60 mg a day, still capped at 6-8 weeks, because nothing above that appears in the material used here |
| Female | Not recommended, or low supervised doses only; the compound has a history of female use but the virilization risk is real |
| Administration | Oral, once or twice daily around a sixteen hour half-life; it is not a compound used to add fluid before a mass phase |
Because the tablet clears quickly but its marker does not, the practical advice for anyone tested is to think about the detection window before choosing the compound rather than afterwards.
Suggested Protocols
Three arrangements that play to what the tablet actually does. The pills lead to the matching pages in this line.
What to Expect
- Strength arrives before size. Week one to two usually brings better numbers in the gym without a matching change on the scale.
- Lean tissue, not water, after a few weeks. The dry, quality portion of the gain shows between week three and week four.
- No fluid and no breast changes. The chlorine substitution removes the estrogenic route entirely.
- Androgenic effects are milder, not gone. Acne and hair changes still occur in users who are prone to them.
- Lipids and enzymes move. HDL falls while LDL and liver enzymes rise, which is the price of the methyl group.
- Six to eight weeks is the ceiling. Beyond that the hepatic exposure is not worth the remaining returns.
- The detection tail is long. A long-lived metabolite has been found six weeks after one oral dose, which makes this a poor pick for tested athletes.
Side Effects and Management
A modest androgenic profile with the usual methylated-oral considerations, ordered from most to least common.
Post-Cycle Therapy
The tablet itself is gone within a day of the last dose, so the start date depends on the injectable in the cycle rather than on the oral.
