Every product, one index

This page is the research peptides catalogue reduced to its plainest form: all 30 products, grouped by format, one line each, with the price including VAT and a link to the page that documents it. The shop presents the same products with photographs and descriptions; this index exists for the visitor who already knows the compound and wants the list.

The four formats are four answers to one handling question. A vial leaves reconstitution and concentration to the bench, a pen fixes both at manufacture, a spray delivers a metered volume of solution without a needle, and a capsule exists only where a molecule survives digestion. None is a better product than the others; each puts a different amount of preparation between the parcel and the work. The pen versus vial comparison is the page to read when the choice is not obvious.

Every product page carries the same two things: a specification of what is in the container and the route to the certificate of analysis for the batch in stock. Nothing is released below 99% purity by HPLC, the certificate is issued per batch, and you can ask for it before paying rather than after. The quality page describes the testing and release process behind that sentence.

Ordering runs through a basket and Stripe Checkout. Each product page has an add-to-basket button; the basket lives in your browser until you start checkout, at which point Stripe’s hosted payment page takes over, shows the methods available for your country and handles the card details, which never pass through this site. Once payment is confirmed the order goes to dispatch, which leaves within 24 hours on working days in plain packaging with tracking. The shipping page carries the detail.

Research vials

Lyophilised powder; you set the concentration

A vial holds lyophilised powder and nothing else, so the concentration is set at the bench rather than at the factory: bacteriostatic water goes in and the volume goes in the notebook. Dry powder tolerates the temperatures of ordinary transit, whereas a reconstituted solution runs on a clock, and the stability literature on PubMed is the basis for both statements.

Pre-filled pens

Fixed concentration, metered increments

A pen fixes the concentration at manufacture and meters a set volume per click, which removes the reconstitution step and one variable from your records. The trade is flexibility: the fill is what it is. Most of the catalogue takes this form.

Nasal sprays

Short sequences only, chain length decides

The peptides on this shelf are all short sequences, because nasal absorption falls away quickly as chain length grows; NAD+, a coenzyme rather than a peptide, is the one item here that the rule does not describe. Each pump delivers a fixed volume of solution, so a spray arrives ready and is refrigerated once opened. The spray versus injection page explains what the mucosal route gives up in exchange for doing without a needle.

Capsules

The structural exceptions that survive digestion

Two oral products, both here for structural reasons rather than convenience: Dihexa is a small molecule rather than a peptide, and the BPC-157 and KPV pairing is the rare case of sequences stable enough for the oral route to be worth studying. Every other peptide in the catalogue would be broken down before it was absorbed.

Diluent

The bottle every vial order needs

Bacteriostatic water is the one item here that is not research material in its own right and the one every vial order assumes. The benzyl alcohol content is what allows repeated draws from a single bottle, and the twenty-eight-day convention after first puncture is set out on its product page.

The pages that make buyers dangerous

Three reads that turn a price comparison into a real one.
