Turkesterone is a phytoecdysteroid commonly marketed from Ajuga turkestanica extracts as a “natural anabolic” sports supplement. It is not a peptide, not a SARM, and not an FDA-approved anabolic drug. Controlled human evidence for hypertrophy is weak/negative in preliminary work; product labels often fail identity/quantity tests in broader botanical-supplement research.
Turkesterone is an ecdysteroid (insect/plant steroid-related structure), not a mammalian anabolic-androgenic steroid medicine, not a SARM, and not a peptide.
Sold as dietary supplement ingredient(s) — FDA does not pre-approve. Ecdysterone has appeared on WADA’s monitoring program historically; that is not automatically identical to listing turkesterone as prohibited — athletes should verify current WADA monitoring vs prohibited status and GlobalDRO. Do not assume “natural = allowed.”
Key takeaways
- Not a peptide and not a SARM — plant ecdysteroid.
- “Natural anabolic” marketing ≫ robust human hypertrophy proof.
- Preliminary human studies have not shown clear body-composition wins at studied conditions
- Botanical supplement label accuracy is a documented problem class.
- No dosage charts; we don’t sell supplements either.

What is turkesterone?
Turkesterone is one of several ecdysteroids discussed in sports nutrition. Marketing often pairs it with ecdysterone (20-hydroxyecdysone). They are related phytochemicals, not interchangeable evidence bags without citations.
| Chemistry class | Phytoecdysteroid |
|---|---|
| Peptide? | No |
| SARM? | No |
| Typical market form | Ajuga extract / isolated claim |
| Human hypertrophy proof | Weak / not established |
Also known as
- Turkesterone — compound name.
- Ajuga turkestanica extract — common source claim on labels.
- Related discussion: ecdysterone — sibling ecdysteroid (not identical).
- Mis-tags: “turkesterone peptide,” “natural SARM.”
SARMs are synthetic AR modulators. Ecdysteroids are a different chemical class. “Natural SARM” is marketing oxymoron territory.
How is turkesterone classified?
Dietary-supplement phytochemical / ecdysteroid in consumer markets — not an approved anabolic drug.
What is turkesterone not?
| Turkesterone is not… | Why that matters |
|---|---|
| A peptide | Phytochemical |
| A SARM | Different class |
| Proven steroid-replacement | Human evidence weak |
| Guaranteed label-accurate powder | Botanical adulteration/identity issues exist |
| Something we dose | Refusal |
How is turkesterone thought to work?
Proposed mechanisms in secondary literature invoke non-AR pathways and protein-synthesis narratives familiar from ecdysteroid marketing. Mechanism speculation ≠ proven human hypertrophy.
What human vs animal vs label evidence exists?
| Evidence type | What exists (summary) | Maturity |
|---|---|---|
| Human preliminary | Small/acute studies reporting limited or null effects on body composition / IGF-1 / metabolic proxies in early investigations | Human Weak |
| Animal / in vitro | Ecdysteroid anabolic-adjacent models | Animal/Cell |
| Supplement assays | Broader literature shows botanical sport supplements often mislabeled | Human Product quality |
| Approved drug label | None as anabolic drug | None |
Lock MDPI/ACSM abstract citations before quoting null results in publishable copy; do not invent effect sizes.
What has turkesterone been studied for?
Sports-supplement hypertrophy/metabolic proxies; comparative interest with ecdysterone. Studied thinly ≠ proven.
What safety topics come up?
Generally marketed as “natural,” which is not a complete safety argument. Unknown long-term high-dose use; product misidentity means you may not be ingesting the labeled ecdysteroid. Not medical advice.
What is turkesterone's regulatory status?
- U.S.: Dietary supplement ingredient context; structure/function claims are manufacturer-responsible.
- WADA: Confirm whether ecdysterone remains monitored and whether turkesterone appears on prohibited vs monitoring lists for the active year — — do not assume either “banned like a SARM” or “always allowed.”
- Athletes: When in doubt, GlobalDRO + batch-tested products — still not a recommendation to use.
Why doesn't this page include a dosage chart?
Supplement protocol charts refused; evidence too weak to present as dosing guidance anyway.
Related lab literacy
Not peptide reconstitution.

- Ostarine / RAD-140 — true SARMs (do not equate).

Frequently asked questions
Is turkesterone a peptide?
No.
Is turkesterone a SARM?
No. It is an ecdysteroid.
Does it build muscle like steroids?
Human evidence does not support steroid-like claims; preliminary studies are weak/null-leaning.
Is it WADA banned?
Do not assume. Ecdysterone was not found by name on the 2026 Prohibited List page we checked; still check the current list and GlobalDRO.
Why no dosage chart?
Weak evidence + YMYL supplement-protocol refusal.
Not a peptide, not a SARM, not medical advice. Disclaimer..
