UK Peptide Pricing Tracker — July 2026 Update

About This Tracker

This tracker compares Peptify UK's prices against six other UK research peptide suppliers on 10 popular research products. The goal is transparency: researchers deserve honest, current pricing information — including the products where Peptify is not the cheapest.

All prices in this July 2026 update were fetched from each supplier's public website on 16 July 2026, and a sample from every supplier was independently re-checked the same day before publication. Only standard single-vial retail prices are compared, and only like-for-like vial sizes — where a supplier sells a different size, we mark it N/A with a footnote rather than publish a misleading number.

Peptify UK is operated by PEPTIFY LIMITED (Companies House #17021295). Every Peptify price below links to a product page carrying that batch's downloadable Janoshik Analytical Certificate of Analysis.

July 2026 Price Comparison

¹ Supplier sells this compound only in smaller vial sizes — not compared to avoid a misleading per-vial figure. ² Sold only in a different vial size (e.g. GHK-Cu 60mg, TB-500 10mg, Ipamorelin 6mg at £100 flat). ³ On sale at time of check (regular £58.30). ⁴ NAD+ sold only as a 1000mg kit (£295.00). ⁵ Sold under the coded listing "RTX3", described as a triple GLP-1/GIP/glucagon receptor agonist — retatrutide's mechanism; 10mg variant price. ⁶ N-acetyl amidate analog of the compound, not the plain peptide. ⁷ Sold only as a multi-vial bundle of separate vials, not a single blended vial (XL Peptides 6-vial bundle £89.99, out of stock at time of check; Pure Peptides bundle ≈£189). ⁸ Closest blend is a 3-peptide 70mg vial without KPV (£89.00).

What Changed Since the April Edition

Peptify cut the GLP-3 (RT) 10mg price from £64.99 to £59.99. GLP-3 (RT) is Peptify's listing for the triple-receptor research peptide also known as retatrutide — and it is now the only openly named retatrutide listing among the suppliers tracked. In April several suppliers carried it; in July, none of the other six list it under its own name (one sells a coded equivalent at £98.99 for 10mg).

The supplier panel was refreshed. Two suppliers from the April edition no longer publish comparable prices and were replaced with three that do (Tide Labs, Regen Peptides, MY PEPTIDES), so this edition tracks seven suppliers in total.

NAD+ 500mg now shows the widest price spread of any tracked product: £40.00 to £96.99 for the same vial size — a 2.4x difference that makes supplier choice unusually consequential for NAD+ research programmes.

Key Takeaways — July 2026

Peptify is the lowest-priced supplier on 4 of the 10 tracked products: GLP-3 (RT) 10mg (£59.99 — 39% below the only comparable listing), Ipamorelin 10mg (£29.99 vs £45.00+ elsewhere), Selank 10mg (£24.99 for the plain peptide), and the four-peptide KLOW-type single-vial blend (£69.99 vs £75.00–£200.00).

On another three products Peptify is within £2 of the cheapest same-size listing: BPC-157 10mg (£26.99 vs £25.00), GHK-Cu 50mg (£18.99 vs £17.99), and NAD+ 500mg (£44.99 vs £44.95).

In the interest of honesty: Peptify is not the cheapest on TB-500 5mg (£24.99 — Regen Peptides lists £15.00) or Semax 10mg (£34.99 — three suppliers list it lower). Every Peptify batch ships with its own-name Janoshik COA published on the product page, which not all lower-priced listings provide; researchers should weigh documentation alongside price.

Bacteriostatic water remains commoditised at £6.00–£8.50 for 10ml across all suppliers who stock it.

How We Collect This Data

Prices are collected from each supplier's public website. For this edition every price was fetched live on 16 July 2026, recorded with the exact listing name and URL, and one price per supplier was independently re-fetched the same day as an accuracy check before publication — all seven spot-checks matched.

Only UK-based suppliers with publicly listed prices are included. Standard single-vial retail prices only: member-only prices, multi-buy tiers, and subscription pricing are excluded. Where a listing was on sale at the time of the check, the current effective price is shown with the regular price footnoted.

Suppliers change prices without notice; treat this as a snapshot dated 16 July 2026. The next update follows in the first week of August 2026.

Frequently asked questions

How often is this pricing tracker updated?

The tracker is refreshed with newly fetched prices roughly monthly. The current edition's prices were collected and spot-verified on 16 July 2026; each edition states its exact check date.

Which UK supplier has the cheapest BPC-157 10mg in July 2026?

Among the seven suppliers tracked, Regen Peptides lists BPC-157 10mg at £25.00 and Peptify at £26.99. Peptify's listing includes a batch-specific Janoshik Certificate of Analysis published on the product page.

Who sells retatrutide in the UK in 2026?

As of 16 July 2026, Peptify's GLP-3 (RT) 10mg (£59.99) is the only openly named retatrutide-class listing among the suppliers tracked; one other supplier sells a coded equivalent at £98.99. It is supplied strictly for in-vitro research use.

Why are some prices marked N/A?

N/A means the supplier does not sell that product in the same vial size, only sells it as a bundle rather than a single vial, or does not stock it at all. Comparing different vial sizes head-to-head would be misleading, so we footnote instead.
