Five organ-specific peptide bioregulators in one capsule. Built on the research of Professor Vladimir Khavinson and the St. Petersburg Institute of Bioregulation and Gerontology.
Each capsule delivers 75 mg of active peptides. That breaks down to 15 mg each from prostate, testes, adrenal, thyroid, and hypothalamus tissue.*
- May support normal prostate function and male reproductive activity*
- Helps maintain a healthy stress response and normal adrenal function*
- Supports normal thyroid activity and metabolic balance*
- Contributes to coordinated daily wellness as part of a healthy lifestyle*
- Hormone free, non-GMO, and made under strict quality standards
Available in 20 and 60 capsule packs.
Why Men Pick Man 5
Most men start with one or two single peptide complexes. After a course or two, they want broader coverage without taking five separate bottles. Man 5 was built for that next step.
One capsule covers five tissue sources that work together in male physiology. You get prostate, hormonal, stress, thyroid, and central regulatory support in a single daily routine.*
Pick Man 5 if you want:
- Multi-system daily peptide support in one product
- A simpler routine than stacking three or four single peptides
- Khavinson-lineage peptides backed by 40 plus years of research
- A formula that fits standard 30-day course protocols
What's Inside Each Capsule
A-16 Libidon (15 mg) — Prostate peptides. May support normal prostate tissue activity and male reproductive function.*
A-13 Testoluten (15 mg) — Testis peptides. May support normal testicular activity within the body's natural range.*
A-17 Glandokort (15 mg) — Adrenal peptides. May support a healthy stress response and normal adrenal function.*
A-2 Thyreogen (15 mg) — Thyroid peptides. May support normal thyroid activity and metabolic balance.*
Hypothalamus Peptides (15 mg). May support normal regulatory coordination of daily body cycles.*
Other ingredients: microcrystalline cellulose, gelatin (capsule), lactose, calcium stearate.
How to Take Man 5
Adults: 1 to 2 capsules, twice daily, with food.
Course length: 30 days.
Repeat: every 4 to 6 months, or as your routine calls for.
You can stack Man 5 with other peptide complexes. Most people run up to five peptide products at one time without issue. See the stack suggestions below for popular pairings.
Who Man 5 Is For
Adult men who want broad daily peptide support in one capsule. Many users start regular peptide protocols between ages 35 and 45, when single-organ formulas no longer cover the full picture. Man 5 is also a fit for men already running Khavinson peptides who want a simpler daily core.
Not for men under 18, women who are pregnant or breastfeeding, or anyone with a known sensitivity to any ingredient. Talk to your doctor if you take prescription medication.
The Research Behind It
Professor Vladimir Khavinson and his team at the St. Petersburg Institute of Bioregulation and Gerontology spent more than four decades studying short peptide complexes. Their core idea is simple: peptides drawn from a specific tissue may help that same tissue carry out its normal job.
Man 5 follows that principle and groups five tissue sources known to play a role in male physiology. Each peptide complex in the formula traces back to that same research lineage.
Stack Suggestions
Pair Man 5 with single peptides for targeted needs:
- For circulation support: A-3 Ventfort
- For rest and daily rhythm support: A-8 Endoluten
- For immune balance support: A-6 Vladonix

Common Questions
Are peptides the same as hormones?
No. Peptides are short chains of amino acids. They are not hormones and they do not replace hormones in the body.
How fast do peptide bioregulators work?
Most users run a full 30-day course before reviewing how they feel. Many run a second course three months later for steady support.
Can I take Man 5 with other supplements?
Yes. Man 5 can be combined with most daily supplements and with up to four other peptide complexes at one time.
Are there side effects?
Decades of clinical use have not flagged serious side effects when taken as directed. Stop use and contact your doctor if you notice any unusual reaction.
What's the difference between Man 5 and Polo 3 Plus?
Polo 3 Plus contains three peptide complexes (prostate, testes, adrenal). Man 5 adds thyroid and hypothalamus peptides for broader daily coverage. Compare them on the Polo 3 Plus product page.

Links removed (don't exist on firma-vita.com)
- The peptide stacking guide blog link was removed. Firma Vita has no blog. The CTA was rewritten to point readers to the stack suggestions section instead.
- The "What Are Peptide Bioregulators" blog link was removed for the same reason.
- The "Peptides for Men" collection link was replaced with the Male Reproductive System Peptide Bundle product link plus a fallback to /collections/all. Firma Vita uses tag-based collections like
/collections/all/adrenal-health, but no men-specific tag exists.
Other items to verify before publish
- Pack sizes: Confirm Firma Vita Man 5 is sold in 20/60 capsule packs (matches Polo 3 / Vision 3 / Thyro 3 convention).
- Other ingredients line: Lifted from Vitual product spec (microcrystalline cellulose, gelatin, lactose, calcium stearate). Confirm Firma Vita's actual capsule composition matches before publish. If different, send the supplement facts panel and I'll update.
-
JSON-LD placement: Wrap in a Liquid conditional like
{% if product.handle == 'man-5-peptide-complex-mens-health' %}so the FAQ schema only fires on the Man 5 page. - Post-publish verification: Use incognito + view-source to confirm rendering. Run the live URL through Google's Rich Results Test for the FAQ schema.
- Compliance: All claims use hedged structure/function language. No disease names, no testosterone-stimulation claims, no erection or libido claims, no anti-aging claims. The FDA disclaimer is bold at the bottom of the description and should stay as is.
- Future blog opportunity: Once a blog launches on firma-vita.com (or once the QI Supplements blog is the canonical source), update the "Stack Suggestions" and "Research Behind It" sections to point at the relevant articles. Worth 2–3 minutes of CRO and SEO uplift.
