how to choose a peptide bioregulator
A comparison of all the NPCRIZ lines
A peptide bioregulator is chosen on three things: the origin of the peptides (natural cytomaxes, extracted from tissues of animal origin, or cytogens synthesised in a laboratory), the form it comes in (capsules or sublingual drops) and the tissue or organ system stated by the manufacturer as the source the peptides were isolated from. The GAVAU.LT catalogue of 2026-07-29 holds 64 active NPCRIZ peptide bioregulators, grouped into six lines; prices range from 65,20 € (sublingual cytogens) to 468,70 € (GPL complexes). All of them are sold in the European Union as food supplements, not as medicines.

The short answer: where to start
This list is ordered by how many decisions the buyer has to make — from the simplest choice to the most involved. It is not a ranking of effectiveness.
A first course, with no restrictions
A natural cytomax in capsules (20 or 60 capsules, 142,30–393,40 €). The widest choice: 21 options, one for each tissue described by the manufacturer.
Natural cytomaxes arrow_forwardYou are avoiding raw material of animal origin
A synthetic cytogen (60 capsules, 144,00 €) or a sublingual cytogen (drops, 10 ml, 65,20 €).
Synthetic cytogens arrow_forwardYou want the lowest starting outlay
A sublingual cytogen – 65,20 €. This is the cheapest way to try the category.
Sublingual Cytogens arrow_forwardYou find capsules hard to swallow, or you want to bypass the digestive tract stage
A sublingual cytomax (drops, 10 ml, 78,70 €).
Sublingual Cytomaxes arrow_forwardYou want one combined preparation instead of several
Prime Peptide® (133,90–184,10 €) or GPL (468,70 €).
How this comparison was put together
So that the comparison can be checked, here are the criteria:
All names, pack sizes, tissue assignments and prices are taken from the GAVAU.LT catalogue of 2026-07-29. Prices may change — the current price is always shown on the product page.
Only active products that can be bought at the moment. Inactive or discontinued lines are not included in the tables.
The peptide origin stated by the manufacturer (NPCRIZ) — the tissue the peptides were isolated from, or the system the preparation is assigned to. This describes the composition, not an effect.
We do not rate or rank products by effectiveness. Peptide bioregulators are food supplements, and in the European Union there are no authorised health claims for them under Regulation (EC) No 1924/2006. More on this: what may and may not be claimed.

Cytomaxes or cytogens — what is the difference?
Cytomaxes are peptide complexes extracted from tissues of animal origin, while cytogens are individual short peptide sequences synthesised in a laboratory. The practical difference for the buyer: the catalogue holds 21 cytomax options and they use raw material of animal origin, while the cytogens have 6–7 options and are made synthetically. In capsule form cytogens cost 144,00 €, cytomaxes 142,30–393,40 €; in sublingual drop form cytogens 65,20 €, cytomaxes 78,70 €. In more detail: Peptide Guide: Cytomaxes vs Cytogens.

Capsules or sublingual drops?
Capsules come in packs of 20, 30, 60 or 90 capsules, and the sublingual form in a 10 ml bottle with a dropper: the drops are placed under the tongue, avoiding first-pass metabolism in the liver. Capsules are simpler to take and more convenient when travelling; the sublingual form is chosen when swallowing capsules is awkward. Both forms come from the same manufacturer and the same peptide line. In more detail: Peptide forms and how to take them.
Capsules

The drops are placed under the tongue, avoiding first-pass metabolism in the liver; chosen when swallowing capsules is awkward.
Natural cytomaxes by the tissue stated by the manufacturer
Each cytomax has its own tissue or organ system from which the peptides are isolated. Almost all come in both forms — capsules and sublingual drops.

The Prime Peptide® line
Prime Peptide® differs from the pure cytomaxes and cytogens in that the peptides are combined with additional functional ingredients. It is always worth checking the composition on the product page.

| Prime Peptide Brain | Brain, cognitive function | 150,70 € |
| Prime Peptide Collagen | Skin, hair, nails | 133,90 € |

GPL complex peptides
A two-product line — GPL FEMME for women and GPL MAN for men, 30 capsules each, 468,70 €. These are the most expensive peptide preparations in the catalogue; the manufacturer describes them as complexes that bring together several peptide areas in one preparation.
What GAVAU.LT does not offer
GAVAU.LT does not trade in injectable research peptides — BPC-157, TB-500, CJC-1295, Ipamorelin, GHK-Cu, Retatrutide, Tirzepatide, MOTS-c, Semax or Selank in injectable forms. That is a separate market category, subject to different rules, and it is not food supplements. Every peptide product sold by GAVAU.LT is an oral or sublingual food supplement. The difference is explained here: peptide bioregulators vs injectable research peptides.
Common questions when choosing
How much do peptide bioregulators cost at GAVAU.LT?
The prices on 2026-07-29 are as follows: sublingual cytogens 65,20 €, sublingual cytomaxes 78,70 €, cytogens in capsules 144,00 €, natural cytomaxes 142,30–393,40 €, Prime Peptide® 133,90–184,10 €, GPL complexes 468,70 €. The current price is always shown on the product page.
Can several peptide bioregulators be combined?
The manufacturer presents the different options as combinable with one another. When taking several supplements together, and especially alongside medicines, it is worth consulting a doctor or pharmacist.
Which peptide is the best?
There is no honest answer to that question. Peptide bioregulators are food supplements, they have no authorised health claims, and so GAVAU.LT does not rank them by effectiveness. The choice rests on origin, form, price and the focus stated by the manufacturer — all of it compared in the tables above.
How long does delivery take?
To Lithuania — within 1–2 working days; to other European Union countries — within 2–4 working days with DHL Express, or 2–10 working days with standard shipping.
