Quick read
Firma Vita just rolled out six new Khavinson peptide complexes. Each one combines two or three natural peptides into a single capsule. Same peptides you know. Fewer bottles to take.
The six complexes:
- Vision 3 for eye and visual system support
- Cardio 3 for heart and vascular support
- Neuro 3 for brain and nervous system support
- Polo 5 for male health support
- Thyro 3 for thyroid, adrenal, and immune support
- Urinary 3 for kidney and bladder support
One capsule replaces two or three. Same daily dose. Same Khavinson research lineage.

What is a peptide complex?
A peptide complex is a single capsule that contains two or more Khavinson peptide bioregulators at full dose. The peptides inside are natural peptides standardized for use in supplements. Instead of taking three separate bottles, you take one.
The peptides inside the complex are the same short amino acid chains that Professor Vladimir Khavinson and his team identified at the St. Petersburg Institute of Bioregulation and Gerontology over the last 40 years. Professor Khavinson has authored over 700 scientific publications on peptide research, and the body of work covers how these peptides modulate gene expression and protein synthesis at the cellular level. Each peptide is tissue specific. The complex just packages them together for systems that work together.
Why does this matter? Most body systems are not single tissues. Your eyes depend on the retina, the brain pathways that process vision, and the small blood vessels that feed them. Your heart depends on cardiac muscle, the vascular system, and the immune environment they live in. A complex supports the whole system instead of one piece of it.
The research behind Khavinson peptides
Over 700 scientific publications exist on Khavinson peptide research. The work spans more than four decades and covers biochemistry, molecular biology, and applied pharmacology. The history of the research traces back to the 1970's, when Professor Khavinson began isolating tissue-specific peptides at the institute that became SPIBG in Russia.
A 2014 review by Khavinson and colleagues mapped the body of evidence up to that point. It remains one of the most cited reference works in the field. Interest in peptide bioregulators has grown steadily since, with new publications added each year.
A few highlights worth knowing before you pick a complex:
Gene expression and protein synthesis. Research has shown that Khavinson peptides modulate gene expression and protein synthesis in the tissues they target. This is the proposed mechanism behind their tissue-specific effects.
Tissue repair and maintenance. Published studies have looked at how these peptides support the repair and maintenance of specific tissues including the brain, liver, and other organ systems. Each peptide carries a tissue address.
Longevity research. Khavinson peptides sit at the center of the longevity research conversation. Long-term studies on elderly populations have reported reductions in all-cause mortality among participants taking peptide bioregulators across multiple-year follow-ups. Research suggests these peptides may slow the aging process by improving cellular repair.
Safety record. Decades of clinical use and published research have shown Khavinson peptides to be well tolerated, with no significant side effects reported across the long-term studies. As with any supplement, talk to your doctor before starting if you take prescription medication or have a diagnosed condition.
Firma Vita is one of the most popular brands carrying these formulations today, with distribution from Russia to the USA, Australia, and most countries worldwide. For a deeper read on the research, see our Khavinson peptides explainer.
Why we like the complex format
Three practical reasons.
One bottle, not three. A 30 day protocol with three bioregulators means three bottles on your counter and three doses to remember. A complex puts the same peptides in one bottle. Easier to take. Easier to travel with.
Same active dose. Each complex contains 30 mg of active peptides per capsule. A useful fact: the peptides inside are at the same potency as the individual bioregulators we already carry. The complex format does not dilute anything.
Built around how the body actually works. The complexes pair peptides for connected systems. Vision 3 pairs the retinal peptide with the brain and blood vessel peptides because vision depends on all three. Cardio 3 pairs the heart peptide with vascular and immune peptides because cardiovascular wellness is not just the heart. The pairings are not random.
If you already own the individual bioregulators, you can stack them with a complex to increase the dose of a specific peptide. The complex is not a replacement for stacking. It is a simpler starting point.
The six new Firma Vita complexes
Vision 3: Visual System Peptide Complex
Inside: A-11 Visoluten (retina peptides), A-5 Cerluten (brain peptides), A-3 Ventfort (blood vessel peptides).
Your eyes process more than three quarters of the information your brain receives. Vision is not just what happens in the eye. The retina sends a signal. The brain reads it. The blood vessels keep both fed.
Vision 3 covers all three. It pairs Visoluten for retinal tissue, Cerluten for the brain pathways that process vision, and Ventfort for the microvascular delivery to the eye.
The Visoluten peptide has been studied in clinical research for its potential to support visual acuity and retinal function in age-related visual changes. The Khavinson team has published on its tissue-specific action in retinal cells.
Pick this if you want the full visual system protocol in one capsule. For the deeper dive on eye peptides, read Best Peptides for Eye Health and Vision Support After 50.
$215. 60 capsules. 1 to 2 capsules daily with meals for 30 days.
Cardio 3: Cardiovascular System Peptide Complex
Inside: A-14 Chelohart (heart peptides), A-3 Ventfort (blood vessel peptides), A-6 Vladonix (thymus and immune peptides).
The heart beats around 100,000 times a day. The vascular system that supports it spans more than 60,000 miles. Cardiovascular wellness is not one structure. It is a system.
Cardio 3 brings together three peptides that support that system end to end. Chelohart for cardiac muscle tissue. Ventfort for vascular tone and circulation. Vladonix for the immune balance that underlies long term cardiovascular wellness.
Most cardiovascular supplements stack a few antioxidants and call it complete. Cardio 3 is built on a different premise. Support the heart, the vessels, and the immune environment they live in, all at once.
$215. 60 capsules. 1 to 2 capsules daily with meals for 30 days.
Neuro 3: Nervous System and Brain Peptide Complex
Inside: A-5 Cerluten (brain peptides), A-3 Ventfort (blood vessel peptides), A-7 Svetinorm (liver peptides).
The brain runs on roughly 20% of the body's energy and uses around 20% of the oxygen the heart pumps. It is also one of the most metabolically demanding tissues you have.
Neuro 3 targets the systems the brain depends on. Cerluten for the brain tissue itself. Ventfort for the cerebral circulation that delivers oxygen and nutrients. Svetinorm for the liver function that filters the bloodstream supplying the brain.
Research on Khavinson brain peptides has explored their potential to support synaptic plasticity and offer neuroprotective effects in aging models. These studies are part of the broader body of work on how peptide bioregulators support cellular repair in nervous system tissue.
Pick this if your goal is broad brain and nervous system support without building a five product stack. For the deeper protocol with Cerluten, Ventfort, and Svetinorm as separate bioregulators, read Khavinson Nervous System Stack.
$215. 60 capsules. 1 to 2 capsules daily with meals for 30 days.
Man 5: Male Health Peptide Complex
Inside: A five peptide complex covering the prostate, testes, adrenal, vascular, and immune systems.
Most male health products take one swing at one tissue. Man 5 takes a different approach. Five peptides covering the connected systems that male wellness depends on, in one capsule.
This is the largest complex in the lineup. For the matching protocol built on individual bioregulators, see Peptides for Men Over 50.
$289. 60 capsules. 1 to 2 capsules daily with meals for 30 days.
Thyro 3: Thyroid, Adrenal, and Immune Peptide Complex
Inside: A-2 Thyreogen (thyroid peptides), A-17 Glandokort (adrenal peptides), A-6 Vladonix (thymus and immune peptides).
Thyroid wellness is rarely about the thyroid alone. The adrenal glands manage the body's stress response, which directly affects how the thyroid works. The immune system shapes the inflammatory environment that both glands operate in.
Thyro 3 packages all three signals. Thyreogen for thyroid tissue. Glandokort for the adrenal axis. Vladonix for the immune balance that ties the two together.
Vladonix is part of the thymus peptide family that includes Thymalin and Vilon. Published research has explored how these thymus-derived peptides support T-cell production and adaptive immune function, particularly in older adults.
Pick this if you want broad endocrine system support in one bottle.
$215. 60 capsules. 1 to 2 capsules daily with meals for 30 days.
Urinary 3: Urinary System Peptide Complex
Inside: A-9 Pielotax (kidney peptides), A-12 Chitomur (bladder peptides), A-6 Vladonix (thymus and immune peptides).
Urinary wellness is one of those things people do not think about until they have to. By then, the conversation is already reactive.
Urinary 3 is built for the people who want to stay ahead of it. Three peptides supporting the full urinary tract. Pielotax for kidney tissue and natural filtration. Chitomur for bladder tissue and normal urinary function. Vladonix for the immune environment around the urinary tract.
Works for both men and women. Fits into a long term wellness routine without stacking three separate bottles.
$215. 60 capsules. 1 to 2 capsules daily with meals for 30 days.
How to pick the right complex
Match the complex to the system you want to support. The pairing is direct.
| If your goal is | Pick |
|---|---|
| Eye health and visual support | Vision 3 |
| Heart and circulation support | Cardio 3 |

Each product page lists the exact peptide composition, the suggested protocol, and the full dosing information. View the full lineup on our website to compare. If you are already taking individual Khavinson bioregulators and want to step into a complex, pick the one that matches the system you are working on. You can also stack a complex with an individual peptide to increase the dose of one specific bioregulator inside it.
Dosing and protocol
All six complexes follow the same Khavinson cycle.
Dose: 1 to 2 capsules per day, taken with meals.
Cycle length: 30 days, then off for several months, then repeat.
How often: Most people run a cycle every six months. Peptide bioregulators work slowly and the effect compounds across cycles.
Read the suggested use on each product label and follow the protocol cycle. Talk to your doctor before starting if you take prescription medication or have a diagnosed condition.
Capsule or sublingual?
The six Firma Vita complexes covered in this article are all capsules. Several of the individual Khavinson peptides are also available as sublingual drops, which absorb directly through the lining of the mouth. The format you pick comes down to preference. Browse the full bioregulator lineup to see both options.
Complex vs individual bioregulators: which should you pick?
Both work. The choice depends on what you need.
Pick a complex if you want simplicity. One bottle, one daily dose, broad system support. Good for people who are new to Khavinson peptides, who want to test a system protocol before going deeper, or who would not stick to a three product stack.
Pick individual bioregulators if you want precision. Single peptide focus. You control the dose of each one independently. Good for people who already use Khavinson peptides and want to dial in a protocol around one tissue.
Or stack both. A complex plus one matching individual bioregulator increases the dose of that one peptide while keeping the rest of the system supported. Cardio 3 plus extra Chelohart if your priority is the heart. Vision 3 plus extra Visoluten if your priority is the retina.
