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 groups NPCRIZ peptide bioregulators into six lines. 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). The widest choice: 21 options, one for each tissue described by the manufacturer.
Natural cytomaxesYou are avoiding raw material of animal origin
A synthetic cytogen (60 capsules) or a sublingual cytogen (drops, 10 ml).
Synthetic cytogensYou want the lowest starting outlay
A sublingual cytogen. This is the cheapest way to try the category.
Sublingual CytogensYou find capsules hard to swallow, or you want to bypass the digestive tract stage
A sublingual cytomax (drops, 10 ml).
Sublingual CytomaxesYou want one combined preparation instead of several
Prime Peptide® or GPL.
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. 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.

View the line| Line | Peptide origin | Form | Package | Price | When it is chosen | What to look out for |
|---|---|---|---|---|---|---|
| Natural cytomaxes | A peptide complex extracted from the tissues of young animals | Capsules | 20 or 60 capsules | see product page | A first course; the classic line, the most widely described | Raw material of animal origin — not suitable for vegans. |
| Synthetic cytogens | Short peptides synthesised in a laboratory | Capsules | 60 capsules | see product page | When raw material of animal origin is being avoided | A narrower choice — 6 options instead of 21. Always check the composition on the label. |
| Sublingual Cytomaxes | Extracted from tissues of animal origin | Sublingual drops | 10 ml bottle with a dropper | see product page | When a shorter course is wanted, or to bypass the digestive tract stage | Dropped under the tongue 10–15 min. before a meal. |
| Sublingual Cytogens | Short peptides synthesised in a laboratory | Sublingual drops | 10 ml bottle with a dropper | see product page | The lowest entry price into the NPCRIZ range | The cheapest line in the catalogue. Every product in this line costs the same. |
| Prime Peptide® | Peptides combined with additional functional ingredients | Capsules | 60 or 90 capsules | see product page | When a targeted combined supplement is wanted instead of a single tissue | It also contains non-peptide ingredients — the composition differs from that of pure cytomaxes. |
| GPL complexes | A complex of several peptides in one preparation | Capsules | 30 capsules | see product page | When one combined preparation is wanted instead of several separate ones | The most expensive line in the catalogue. Only two versions — GPL FEMME and GPL MAN. |
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 more detail: Peptide Guide: Cytomaxes vs Cytogens.
Cytomaxes
- Origin: peptide complexes extracted from tissues of animal origin
- Options: 21 options in the catalogue
Cytogens
- Origin: individual short peptide sequences synthesised in a laboratory
- Options: 6–7 options in the catalogue
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
In packs of 20, 30, 60 or 90 capsules
Simpler to take and more convenient when travelling.
Sublingual drops
10 ml bottle with a dropper
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.

GPL complex peptides
A two-product line — GPL FEMME for women and GPL MAN for men, 30 capsules each. 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 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.
