Peptide bioregulators vs injectable research peptides
One of the most common misunderstandings when searching for “peptides in Lithuania” is not realising that the market holds two completely different categories of peptides. On this page we explain the differences clearly, so that you can make an informed decision.
In brief
| Peptide bioregulators (cytomaxes/cytogens) | Injectable research peptides | |
|---|---|---|
| Examples | Vladonix, Endoluten, Cerluten, Libidon, Visoluten… | BPC-157, TB-500, CJC-1295, GHK-Cu, Ipamorelin, Retatrutide, MOTS-c |
| Form | Capsules, sublingual drops | Injectable solution (subcutaneous or intramuscular) |
| Status in the EU | Food supplements (registered with the VMVT) | Research chemicals / research compounds (not food, not medicine) |
| Scientific basis | 30+ years of clinical research, 800+ publications | Varied — from early-stage research to limited clinical studies |
| Mechanism of action | Selective tissue bioregulation (chains of 2–4 amino acids) | Specific receptor agonists / signal modulation |
| Usual dose | 1–4 mg/day (micrograms of active substance) | µg–mg, usually larger doses |
| Risk of use | Food supplement — take in accordance with the recommended daily dose | Medium to high, depending on the peptide and the dose |
| COA / HPLC needed | No — the manufacturer issues declarations of conformity | Yes — standard practice in the research chemicals market |
| Where to find them in Lithuania | GAVAU.LT (official NPCRIZ distributor) | gFIT Peps, Longevio, Peptide Maxing and other specialist suppliers |
The difference in detail
1. Peptide bioregulators (our speciality)
Peptide bioregulators are short peptide chains (2–4 amino acids), developed at the Institute of Bioregulation and Gerontology on the initiative of Prof. V. Khavinson. The principle of action is based on the concept of a “molecular key”: a particular peptide recognises only a particular tissue.
- Vladonix — thymus gland peptides (for the immune system).
- Endoluten — pineal gland peptides (for the circadian rhythm, melatonin regulation).
- Cerluten — brain peptides (for cognitive function).
- Libidon — prostate peptides (for men's reproductive health).
- Visoluten — eye peptides (for vision).
These products are sold as food supplements — a convenient form (capsules/sublingual) intended for use on your own in accordance with the recommended daily dose; NPCRIZ peptides have been researched for 30+ years.

2. Injectable research peptides (WE DO NOT SELL THEM)
Injectable research peptides are most often synthetic compounds used in the context of clinical research or in an off-label biohacking setting. Examples:
- BPC-157 — a pentadecapeptide studied for its regenerative properties.
- TB-500 (Thymosin Beta-4) — studied for tissue repair.
- CJC-1295 / Ipamorelin — growth hormone secretagogues.
- GHK-Cu — a copper peptide often used in cosmetology and for tissue regeneration.
- Retatrutide / Tirzepatide — metabolic peptides studied for weight loss.
- MOTS-c, Semax, Selank (injectable), Epitalon (injectable).
These products are most often sold as “research chemicals” — they have no food supplement status and no medicinal product authorisation. Standard practice in this market is HPLC/COA batch certificates, because the user takes on responsibility for dosing, sterility and administration themselves.
GAVAU.LT is not part of this market. If you are looking specifically for BPC-157, TB-500, CJC-1295 or similar injectable compounds, we recommend looking at the websites of specialist research peptide suppliers. Among the specialists operating in Lithuania are gFIT Peps, Longevio and Peptide Maxing (information based on public sources; we are not partners).
Which category to choose?
Peptide bioregulators suit you if:
- You want to start with a food supplement form, without injections.
- You are looking for long-term everyday support.
- You value 30+ years of research history and GMP manufacturing.
- You want targeted support for a specific tissue or organ (the immune system, vision, prostate health and so on).
- You are in Lithuania and want the services of an official distributor.
Injectable research peptides suit you if:
- You are familiar with the biohacking / research peptide culture.
- You require HPLC/COA batch certificates.
- You are prepared to administer the injections yourself.
- You understand that these products are neither food supplements nor medicines.
Our position and expertise
GAVAU.LT is the official authorised distributor of NPCRIZ peptide bioregulators in Lithuania and the Baltic States. Our expertise is concentrated specifically in the field of peptide bioregulation. We do not try to compete in the research peptide suppliers' market — that is a different speciality, and we respect that boundary.
If you need peptide bioregulators, peptide bioregulation, cytomaxes or cytogens, we are a specialist supplier in Lithuania: 64 of the 99 active catalogue products are NPCRIZ peptide bioregulators, supplied directly from the institute.
If you need injectable research peptides, look elsewhere. That is the honest answer.
