Prostamax
What do these badges mean?
Evidence tier
- AHuman-validated — Human trials showing positive results and good safety.
- BAnimal-grade — No human trials yet, but solid animal/preclinical evidence of effect and safety.
- CAnecdotal — No human or animal trials — only anecdotal/observational reports.
- DInsufficient evidence — No or insufficient evidence (encyclopedia only — never recommended by the builder).
Safety light
- 🟢 Green — Only mild, manageable side effects; reasonable safety data.
- 🟡 Yellow — Needs active management, has a meaningful contraindication/interaction, or has thin long-term data.
- 🔴 Red — Risk of a hospital-level event — treat with serious caution.
Browse-only — not on the protocol builder's curated shortlist, so the builder won't recommend it.
What is it?
Prostamax is a Khavinson tetrapeptide for the prostate — part of the reproductive/hormone corner of the Khavinson short-peptide bioregulator family, alongside Testagen. Site tier is Anecdotal (4 studies, 0 human). The Lys-Glu-Asp-Pro sequence is anchored in a cited study title in the source ( 23221144), one of the few Khavinson-family sequences not carrying a flag on the sequence itself.
What does it do in my body?
Claimed mechanism: like the rest of the Khavinson family, Prostamax is proposed to act via gene-promoter binding in prostate tissue, framed as supporting prostate and urological health.
How can it help me?
- Where the science stands: Site tier Anecdotal (4 studies, 0 human) — all four are family chromatin-mechanism work, not prostate-outcome studies

Is it dangerous? What are the side effects?
No adverse-event data exists for Prostamax. The family-wide reported profile in the Russian literature is mild and uncommon: occasional injection-site reactions, transient mild headache early in a cycle.
The real risk isn’t the molecule — it’s the supply chain. Khavinson-family peptides are the dominant gray-market counterfeit category in the peptide space, and a peptide marketed on an organ-specific claim it has no clinical outcome data for is an especially easy target for overselling. Third-party COA verification matters more here than for almost any other peptide class.
Regulatory status: Prostamax is research_only in the US — not FDA-approved for human use, sold as a research compound, not eligible for compounding. It is not a controlled substance.
Typical dosing
Talk to your medical provider before starting any protocol. That said, here are the doses most people commonly use — shared for educational purposes so you can have an informed conversation. These peptides are sold for research use only and are not FDA-approved drugs, and this isn't medical advice.
Educational purposes only — this reflects the Khavinson-school protocol convention shared across the family; it is not medical advice.
There is no dosing or cycling data specific to Prostamax, and no prostate-outcome human data exists to inform a protocol around. What exists is only the generic Khavinson-family cycle pattern: a short course of 10–20 days, repeated 2–3 times per year, with synthetic short peptides in the family generally dosed around ~100–200 mcg/day — but none of this has been validated for Prostamax specifically, let alone for a prostate-support outcome.
What should I avoid combining — and what's synergistic?
Prostamax doesn't have a dedicated stacking protocol in our notes — the interactions that matter most are in the safety section above. For how people combine it with other peptides, the deeper-science view has the full detail.
How can I buy this?
Prostamax is available from BioLongevity Labs — use code OHM-15 at BioLongevity for 15% off. As always, buy only from a source that publishes third-party Certificates of Analysis (COAs) confirming identity and >99% purity.
When you use my coupon code to buy peptides with these sellers, you enjoy a discount off retail price, and I make a small commission which helps me to continue to offer this peptide educational site to you for free. I only have affiliate relationships with peptide manufacturers that show evidence that their peptides are 100% manufactured in the US, 3rd party lab tested for purity, transparent COAs posted on their websites, and that have good customer service.
Prostamax (Lys-Glu-Asp-Pro / KEDP) is a Khavinson tetrapeptide for the prostate. Its four citations all demonstrate the family’s general chromatin-remodeling mechanism in senile lymphocytes — not a prostate-specific clinical effect. There are no prostate-outcome human studies. Say so plainly.
| Class | Khavinson tetrapeptide — Lys-Glu-Asp-Pro (KEDP) |
| Mechanism (one line) | Claimed to modulate gene expression for prostate / urological tissue support |
| Evidence base | Site tier Anecdotal (4 studies, 0 human) — all four are family chromatin-mechanism work, not prostate-outcome studies |
| Safety record | No AE data specific to Prostamax; family-wide mild profile assumed; OHM grade D / provisional |
| Regulatory status | research_only in the US, not FDA-approved |
What it is
Prostamax is a Khavinson tetrapeptide for the prostate — part of the reproductive/hormone corner of the Khavinson short-peptide bioregulator family, alongside Testagen. Site tier is Anecdotal (4 studies, 0 human). The Lys-Glu-Asp-Pro sequence is anchored in a cited study title in the source ( 23221144), one of the few Khavinson-family sequences not carrying a flag on the sequence itself.
How it works
Claimed mechanism: like the rest of the Khavinson family, Prostamax is proposed to act via gene-promoter binding in prostate tissue, framed as supporting prostate and urological health.
What the research shows
Site tier is Anecdotal (4 studies, 0 human). The four citations are all the family’s chromatin/heterochromatin in-vitro work in senile/elderly lymphocytes — increased sister-chromatid exchanges and pericentromeric heterochromatin decondensation (Dzhokhadze et al. 2012, 23221144; Khavinson/Lezhava/Malinin 2004, 15085253; plus 19359734, 15612551), all.
These demonstrate the family mechanism, not a prostate-specific clinical effect — there are no prostate-outcome human studies. OHM grade: D / provisional.
Real-world protocol
