What is Zhenoluten?
Plain language first. The technical label stays, but it never stands alone.Overview
A capsule made from calf ovarian tissue, sold for menopause, cycles and fertility. No published human trial supports any of those three uses.
Cytomax peptide fraction A-15, extracted from bovine ovarian tissue of animals under twelve months. Proposed mechanism is tissue-specific modulation of gene expression in ovarian cells. No controlled human efficacy data has been published outside the originating Russian research program.
What it's used for
An oral tissue extract marketed for female reproductive health, cycle regularity and menopause symptoms.
How does Zhenoluten work?
What it does in the body, and where.Zhenoluten is a mixture of small peptides pulled from ovarian tissue, usually from calves under a year old.
- 01Drawn from calf ovarian tissueA Cytomax, extracted from the ovaries of animals under twelve months. Each capsule is described as containing around 10 mg of peptide fractions.
- 02The claim is selective action on ovarian cellsMarketing describes the peptides supporting ovarian cell metabolism and egg maturation. That is a mechanism proposal and has not been demonstrated in people.
- 03It is the female counterpart of Testoluten in the seller's own schemeTestoluten is the testes extract, A-13, and this library has it. Neither has a Cytogen equivalent for the same tissue here, though Testagen is the closest synthetic in the male family.
What else is it used for?
Each use below carries its own evidence level. Approved means regulators have cleared it for that purpose. Investigational means it is in trials. Early research means it is being studied and is not established.

Four things to know about Zhenoluten
How much, and do you cycle it?
The range, and whether you take breaks.Research only, daily, in 10-30 day courses. Daily for 10 to 30 days, then a long break, repeated a few times a year Community practice
The course pattern comes from Russian practice. Suppliers describe the effect as lasting six to twelve months after a course, which is a claim from the sellers rather than a measured result.
Nothing publishedNo figure
No half-life has ever been published for any of the Russian bioregulator peptides, in people or in animals. The research behind them, mostly from one group in St Petersburg, measures effects on tissue, gene activity and lifespan. None of it measures how long the peptide stays in the body.
You can compare this against the whole library to see where it sits.
What does it cost?
Typical dose and cost, in plain numbers.Zhenoluten is not injected
It is taken by mouth (oral). Sold as capsules, so there is nothing to reconstitute and the calculator does not apply. No dose has been established in a published human study.
