Aimed at ovarian tissue in the writeups, but people still take it as a whole-body capsule.
What people say
Zhenoluten is an oral ovarian-tissue peptide mixture labeled A-15. It is not estrogen, progesterone, HRT or a defined synthetic peptide, and product-specific indexed human evidence is absent.
Doses people talk about
The 10 mg value is declared peptide-complex content. Actual forum regimens often included Endoluten and clinician-directed fertility care, so outcome and safety attribution remain weak.
How it may feel
No reliable acute feel is established. Russian forum accounts describe mixed multi-week outcomes—no effect, transient follicle or laboratory changes, and cyst reports—usually amid Endoluten or other fertility care.
Retail capsule label10 mg peptide complex A-15 per capsule
Retail charts build capsule-count courses from this declared content; independent content and dose-response validation are absent.
Forum co-use report2 Zhenoluten capsules daily
One author reported this alongside one Endoluten capsule every few days and later described an FSH change plus a cyst; capsule mass was not restated in the post.
Higher-count forum report2 Zhenoluten capsules twice daily
Another author reported cysts during use and could not identify which co-treatment explained other laboratory changes.
Half-life & effect duration
- Half-life in the body
- Oral ovarian-tissue peptide mixtureNo settled estimate
- Felt duration people report
- Accounts over weeks to monthsNo effect, cysts, lab changes or a temporary follicle-count increase that returned to baseline
Cycles people discuss
Retail and community language uses 10–30-day or one-to-two-month capsule courses with months between repeats. These are marketing and self-care calendars, not trial-validated schedules.
Timing
Retail charts commonly place one or two capsules once or twice daily with meals over 10–30 days. Reviewed forum schedules include two capsules each morning or twice daily, often with Endoluten, and one repeated course separated by three months; none is a trial-validated calendar.
Stacks
Endoluten is the most common named partner; Ventfort and Thyreogen also appear in broader protocols. The reviewed outcome reports often co-used Endoluten or other fertility interventions.
Watch for
Hormone-sensitive conditions: Self-experimentation around estrogen-driven disease is a community red flag, not a studied exclusion trial.

Timing context & sources
Half-life in the body
No product-specific human elimination half-life is established for Zhenoluten A-15.
A-15 is an undefined ovarian-tissue peptide mixture, and the reviewed evidence inventory found no indexed product-specific pharmacokinetic study.
Absence of an indexed PK study does not establish rapid clearance, and findings from other Khavinson products cannot be transferred to A-15.
- Zhenoluten: benefits, dosage and evidence reviewed (opens in a new tab)Read the identity, mechanism, evidence and safety sections: A-15 is an oral ovarian-tissue peptide mixture; no indexed product-specific cell, animal, human, dose-finding or PK study was identified, and reproductive claims are read across from other peptides or an unpublished manufacturer report.Secondary evidence review; absence searches may change, and the page is not a primary clinical study.
Felt duration people report
Community outcomes are mixed across weeks to months, with no dependable isolated onset or durability window.
Forum follow-ups include no effect, cysts, laboratory changes and a transient follicle-count increase that later returned to baseline; Endoluten and other care were frequent co-interventions.
Self-selected translated reports, unverified products, clinician and fertility-treatment confounding, no controls and incomplete amount reporting.
- Zhenoluten reviews — 2024 fertility forum thread (opens in a new tab)Read the Russian-language post and same-author replies: reported regimens included two capsules twice daily or two capsules each morning, usually with Endoluten; follow-ups included cyst reports, FSH change, uncertainty over which co-treatment mattered and continued use.Multiple self-selected authors, fertility-care setting, translated discussion, co-use with Endoluten or other treatment, no verified formulation and no causal attribution.
- Peptides: who took Zhenoluten and Endoluten? (opens in a new tab)Read the Russian-language thread and same-author follow-up: one author described a one-month course, then a two-month repeat three months later; follicle count rose by five after one month and later returned to baseline, and the author explicitly said other treatments produced similar results so attribution was unclear.Single self-report with several other therapies, no stated Zhenoluten amount in the relevant account, no control and translated outcome language.
What people say
- Cycle regularity / menopause-comfort pitch: Vendor and influencer pages claim more predictable cycles, fewer hot-flash stories. Public Reddit follow-ups on those claims are basically missing. forum
- Fertility-prep anecdotes: A shop-review quote about “cycles more predictable.” Uncontrolled, not a fertility trial. anecdote
- Honesty bar: Even sympathetic independent blogs call the 10 mg capsule a manufacturing spec, not a trial-tied dose. forum
- What it does not replace: Estradiol, progesterone, workup for amenorrhea, or cancer screening. forum
- Endoluten pair: Older Russian-language combo writeups put ovary peptides with pineal peptides for reproductive-function talk. Stack credit is mush. trial
Doses people talk about
- Capsule: Commonly 10 mg peptide complex A-15. Two caps ≈ 20 mg complex in box math. forum
- Broad chart: 1–2 capsules, 1–2 times daily with meals, 10–30 days. forum
- Influencer table: Standard 1 cap BID × 30 days (60 caps); maintenance 1 daily × 30; intensive 2 BID × 30 (120 caps). Seller energy. forum
- Intensive then 10-day packs: 2 caps daily × 30 days, then 2 caps daily × 10 days every 1–3 months. forum
- r/Biohackers plan: One poster wanted four intensive cycles in the next year — cost-shock in the same post. anecdote
- Timing copy: With meals, or 5–10 min before, sometimes “morning preferred.” forum
- Framing: Cytomax convention copied across the A-series — not a dose-finding trial. forum
How it may feel
- Days 1–7: No dependable acute feel is established; most reports describe multi-week capsule courses alongside other fertility or hormone-related care. forum
- Weeks 3–8: Russian forum follow-ups include no effect, transient laboratory or follicle changes, and cyst reports during Zhenoluten use, usually with Endoluten or other care; causality is not isolatable. forumanecdote
- End of 30 days: Retail checkpoint. forum
- 3–6 month re-runs: Cytomax calendar, not daily forever. forum
- If nothing changes: No-effect reports exist, and one repeated-course author said follicle counts later returned to baseline and could not be assigned to Zhenoluten because other treatments produced similar results. forumanecdote
Cycles people discuss
- 10–30 day courses, 1–2×/year in quiet independent writeups. forum
- 30-day intensive + quarterly 10-day packs in retail language. forum
- Not daily forever, not pregnancy-safe in the fine print. forum
- Repeat in 3–6 months on originating-group pages. trial
Timing
- With meals: Chart default. forum
- Not estradiol pharmacokinetics. forum
- Course logic: Tissue-complex / gene-expression story, same family as other cytomaxes. forum
- PK honesty: No public human PK for A-15. trial
More on what it is
- What it is: Natural peptide complex from ovarian tissue, Khavinson cytomax A-15. Also spelled Jenoluten in source-hunting posts. Not estrogen. Not progesterone. Not Ovagen (that’s a different liver/GI short peptide on this map). forum
- Why people search it: Perimenopause lists, “ovary bioregulator,” and r/Biohackers source-shopping for four intensive cycles in a year. forum
- Forum volume is thin: The 2024 r/Biohackers thread is mostly “where do I buy” and “pls update” — almost no public n=1 outcome logs. forum
- Independent English review: A 2026 bioregulator-peptides.co.uk writeup said it would not spend money expecting a measurable effect; no indexed human dose-finding trial. forum
- Not: Not HRT, not clomiphene, not IVF meds. forum
- Originating-group notes: Antiaging-systems-style 2011 capsule report talks climacteric / “exhausted ovary” add-on, 1–2 caps 1–2×/day × 30 days. Old, not a modern RCT. trial
Stacks
- Endoluten: Pineal neighbor in older combo writeups. forum
- Ventfort / Thyreogen: Influencer “complete hormone kit” names. forum
- Not a DIY HRT stack. forum
Storage notes
- Capsules: Dry, dark, 2–25 °C talk on bottles. forum
- No mix instructions here: STUDresearch does not list reconstitution charts. forum
Watch for
- Fine print: Individual intolerance, pregnancy, lactation. forum
- GI: Capsule. forum
- Animal-tissue complex. forum
- Hormone-sensitive conditions: Self-experimentation around estrogen-driven disease is a community red flag, not a studied exclusion trial. forum
- Don’t skip gyn care: Bleeding changes, pelvic pain, fertility workups. forum
- Thin independent evidence: Treat outcome claims as marketing until a real diary or trial shows up. forum
- Regulatory: Not approved HRT or fertility drug. trial
- Research-only framing: Discussion of community practice — not a recommendation to use in humans or animals. forum
