Which compound matches your research interest?

Five questions. After every answer you will learn one useful fact about mechanisms, evidence or batch documentation. The result highlights one relevant material and one comparison option from the Peptiva catalogue.

The result is catalogue navigation, not medical advice or a recommendation for human or animal use.

60-second foundation

What are peptides?

Peptides are short chains of amino acids. Their sequence and chemical modifications influence how they behave in a research model.

  • Compound literature does not verify a store product.
  • Purity and identity are different analytical questions.
  • A COA is meaningful only when it matches the supplied lot.
  • Research use only is a limitation, not proof of safety or regulatory approval.

Batch documentation

Check the material, not just the claim

Scientific literature describes a compound. Batch documentation describes the material supplied. Request the available records for the specific product and lot before ordering.

Learn how to read a COA
01Product and lotThe document must match the supplied batch.
02HPLC / LC-MSCheck which methods and results are actually listed.
03Laboratory and dateVerify who tested the material and when.
04Scope and limitsA COA documents the analytical parameters tested for the specified batch. Products are intended strictly for research use only (RUO).

Our standard

Clear information. Consistent presentation.

The Peptiva catalogue combines technical presentation with accessible scientific context. On every page you can compare available specifications and laboratory formats and review research-use limitations before ordering.

The content provides general research context and does not replace scientific literature, a validated laboratory protocol or medical advice.

Complete compound descriptions Each product explains the compound, how it is studied, its proposed mechanism and important limitations of the available evidence.
Clear specifications and formats Nominal content, research format, price and image are presented as connected variants of one material.
Clear information Navigation, product descriptions, cart, customer account and key information are consistently available in English.
Responsible research context Information distinguishes preclinical from clinical evidence and does not provide human dosing instructions or treatment claims.

Verifiable sources

Scientific literature and batch documentation

Compound information is compared with publicly available scientific literature databases. Listing a source does not mean that the institution endorses Peptiva products. Literature about a molecule is not evidence of the composition or quality of a particular batch; appropriate analytical data are required for that purpose.

In vitro research use Clearly stated limitations on every product

Frequently asked questions

Find clear answers about products, variants, orders and delivery. If your question is not answered here, contact us through the contact page.

What does the laboratory dispenser format mean?

The dispenser variant is a laboratory packaging and material-dispensing format. Product identity, declared quantity and storage conditions are stated in the product specification.

It is not an injection or medical device and is not intended for administration to humans or animals.

The vial variant does not include a dispenser.

What is included with the separate dispenser container?

A separate empty container for storing and transporting a compatible dispenser. The dispenser and its contents are not included.

Check dimensions and compatibility before use. The container is not a refrigerated device.

Which payment methods are available?

Cash on delivery is available for physical products when supported by the selected delivery service. A separate purchase of the digital handbook requires confirmed payment before digital delivery. Available payment methods are shown during checkout.

How long does delivery take?

In Croatia, choose BOX NOW parcel-locker delivery (1–2 business days) or DPD delivery to an address (1–2 business days). A BOX NOW locker must be selected before checkout. DPD is available for enabled EU destinations; the estimated time, final rate and all currently available options are shown before the order is confirmed.

Do I need to create a customer account?

An account is not required to browse the catalogue. When available, it provides easier access to customer details and previous orders.

Registered customers also receive an additional 5% off every order with code REGISTRACIJA5. The discount is available exclusively with an active customer account and cannot be used as a guest.

What are the products intended for?

Peptiva Peptides materials are intended solely for lawful in vitro laboratory and analytical use. They are not for administration to humans or animals. An RUO label alone does not determine regulatory status.
