# How to choose a peptide bioregulator: all NPCRIZ lines compared

**URL:** https://www.gavau.lt/en/pages/peptidai-kaip-issirinkti

---


A peptide bioregulator is chosen on three things: the origin of the peptides
(natural cytomaxes extracted from animal tissue, or cytogens synthesised in a laboratory), the delivery form
(capsules or sublingual tablets), and the source tissue or organ system the manufacturer assigns to the
product. As of 2026-07-29 the GAVAU.LT catalogue holds 62 active NPCRIZ peptide bioregulators across six
lines, priced from €78 (sublingual cytogens) to €560 (GPL complexes). All of them are sold in the European
Union as food supplements, not medicines.

Short answer: where to start
This list is ordered by how many decisions the buyer has to make, from fewest to most. It is not an
effectiveness ranking.

A first course, no constraints — a natural cytomax in
capsules (60 capsules, €160). The widest choice: 21 directions, one for each source tissue the
manufacturer documents.
Avoiding animal-derived material — a synthetic
cytogen (60 capsules, €160) or a sublingual cytogen (20 tablets, from €78).
Lowest possible starting spend — a sublingual cytogen
from €78. This is the cheapest way to try the category.
Difficulty swallowing capsules, or wanting to bypass the digestive step — a
sublingual cytomax (20 tablets, from €94).
One combined preparation instead of several — Prime Peptide®
(€160–220) or GPL (€560).


How this comparison was put together

Source: every name, pack size, tissue assignment and price is taken from the GAVAU.LT
catalogue on 2026-07-29. Prices change — the current price is always the one on the product page.
Scope: only active, currently purchasable products. Discontinued or inactive lines are
excluded from the tables.
The tissue assignment is the manufacturer's (NPCRIZ) stated peptide origin — which tissue
the peptides were extracted from, or which system the preparation is assigned to. It describes composition,
not effect.
What is not here: we do not rate or rank products by effectiveness. Peptide bioregulators
are food supplements, and no health claim has been authorised for them in the European Union under Regulation
(EC) No 1924/2006. See what may and may not be claimed.

Cytomaxes or cytogens — what is the difference?
Cytomaxes are peptide complexes extracted from animal tissue, while cytogens are
individual short peptide sequences synthesised in a laboratory. The practical difference for a buyer:
the cytomax range has 21 directions and uses animal-derived raw material, while the cytogen range has 6–7
directions and is produced synthetically. In capsule form the price is the same (€160); in sublingual form
cytogens are cheaper (from €78) than cytomaxes (from €94).
More: cytomaxes vs cytogens.

Capsules or sublingual tablets?
Capsules come 60 to a pack and are intended for a longer course; a sublingual
pack holds 20 tablets that dissolve under the tongue and do not pass through the stomach. Capsules are
simpler to take and easier to travel with; the sublingual form is chosen when swallowing capsules is awkward or
a shorter course is wanted. Both forms come from the same manufacturer and the same peptide line.
More: peptide forms and how to take them.
A note on drops: the liquid PK ("peptide complex") drop series is mentioned as a third form in some
older texts, but as of 2026-07-29 there is no active drop product in the GAVAU.LT catalogue. Only capsules and
sublingual tablets can currently be bought.

All 21 natural cytomaxes by manufacturer-stated source tissue
Each cytomax has its own source tissue or organ system. Almost all are available in both forms — capsules
and sublingual tablets.

The Prime Peptide® line
Prime Peptide® differs from 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.

GPL complex peptides
A two-product line — GPL FEMME for women and
GPL MAN for men, 60 capsules each, €560. These are the most expensive
peptide preparations in the catalogue; the manufacturer describes them as combined preparations bringing
several peptide directions together in one product.

What GAVAU.LT does not sell
GAVAU.LT does not sell injectable research peptides — BPC-157, TB-500, CJC-1295,
Ipamorelin, GHK-Cu, Retatrutide, Tirzepatide, MOTS-c, Semax or Selank in injectable form. That is a
separate market category with different rules, and those products are not food supplements. Everything
GAVAU.LT sells in this category is an oral or sublingual food supplement.

Common questions when choosing
How much do peptide bioregulators cost at GAVAU.LT?
As of 2026-07-29: sublingual cytogens from €78, sublingual cytomaxes from €94, cytomaxes and cytogens in
capsules €160, Prime Peptide® €160–220, GPL complexes €560. The current price is always shown on the product
page.
Can several peptide bioregulators be combined?
The manufacturer presents the different directions as combinable. When taking several supplements together,
and especially alongside medication, it is worth consulting a doctor or pharmacist.
Which peptide is best?
That question cannot be answered honestly. Peptide bioregulators are food supplements with no authorised
health claims, so GAVAU.LT does not rank them by effectiveness. The choice rests on origin, form, price and the
manufacturer's stated direction — all compared in the tables above.
How long does delivery take?
Lithuania 1–3 business days, Latvia and Estonia 3–5 business days, other European Union countries 5–10
business days. Delivery to an LP Express parcel locker in Lithuania is free on orders over €60.
