# Compound Buyer

> An independent UK editorial review of research-peptide suppliers. Strengths, weaknesses, prices, response times and Companies House records, side by side. For research purposes only.

Compound Buyer is an independent UK editorial publication based in London. It publishes long-form, evidence-led reviews of UK-registered research-peptide suppliers and explainer pieces on the regulatory, lab-accreditation and product-documentation issues that affect UK buyers.

The publication is reader-funded. It does not accept advertising, affiliate income, referral commissions, or paid placement. Suppliers cannot pay to enter, leave, or alter a review. Editorial decisions are made in-house by the Compound Buyer editorial desk.

## Editorial position

Findings on this site reflect publicly verifiable evidence at the date of last update, drawn from each supplier's public site, the UK Companies House public register, the ICO register, the public UKAS register where lab accreditation is relevant, and publicly visible Trustpilot or third-party review profiles.

The core editorial framework weights two things highest, because in this market they are what a buyer cannot recover if they skip them: a verified per-batch certificate of analysis from a named third-party laboratory, and protection of the buyer's payment. The full checks applied are:

1. Per-batch certificate of analysis (CoA) from a named, identifiable third-party laboratory such as Janoshik.
2. Payment protection: whether the buyer's money is held until the order arrives and is verified, or exposed on transfer.
3. Pricing transparency: whether prices are published openly or only on request.
4. Honest sourcing: no research peptides are manufactured in the UK, so every UK supplier sources from abroad; the test is whether a seller is straight about that.
5. Responsive, human customer service that knows the product.
6. A track record verifiable through Companies House, independent reputation and prior reviews.

Seven sections: what BPC-157 is (a 15-amino-acid synthetic peptide derived from a fragment of a protein originally identified in human gastric juice by Predrag Sikiric's group at the University of Zagreb), what the preclinical literature describes (gut, tendon and wound healing in rat models), how to read the methodology honestly (intraperitoneal vs oral administration, dose scaling), the missing human evidence (no peer-reviewed clinical trials, no regulator approval anywhere), the regulatory and legal picture (WADA category S0, UK research-use-only framing), what UK buyers actually do with the molecule, and the editorial verdict. For research purposes only.

- [The state of UK peptides in 2025, a market in transition](https://compoundbuyer.news/uk-peptide-market-2025.html): A long-form magazine feature on the UK research-peptide market in 2025. Six sections: regulation (MHRA, ASA), the supply-side shake-out at Companies House, the GLP-1 spillover into the research-peptide channel, the retreat of card-payment processors, the new molecules, and forecasts for 2026. For research purposes only.

- [The UK crackdown on unlicensed weight-loss injections, explained](https://compoundbuyer.news/uk-crackdown-weight-loss-compounds-2026.html): A long-form regulatory editorial on the UK enforcement response to unlicensed prescription-only injectable supply. Covers the offences under the Human Medicines Regulations 2012 and the Pharmacy Order 2010, the lanes of the principal UK enforcement bodies (MHRA, UK Border Force, Trading Standards, National Crime Agency, General Pharmaceutical Council, Advertising Standards Authority, Companies House), the practical pattern of operations, the policy direction, and the legal position for sellers, intermediaries and end-users. No specific brand or compound names. For research purposes only.

- [The best UK wholesale peptide suppliers, scored and ranked](https://compoundbuyer.news/best-wholesale-peptide-websites-2026.html): A long-form editorial review of how to buy research peptides wholesale in the UK, published April 2026 and updated June 2026. Compound Buyer's overriding rule is escrow: it will not recommend any wholesale route that does not hold the buyer's payment until the order has arrived and been verified (no escrow, no recommendation). Compound Buyer approached twenty UK wholesalers and ranks three on a six-point framework that weights payment protection and proof of product highest: holds payment in escrow until the order arrives and is verified, sources from labs that publish per-batch Janoshik-style certificates, helps small as well as bulk buyers, and is candid that, like every UK seller, it sources from abroad), Wholesale Peptides at 6.9/10 (a genuine UK wholesale and dropship operation with a strong Trustpilot rating and WhatsApp contact, but no published prices, no escrow, and a twenty-day lead time it could not evidence as held UK stock), and Peptidy at 6.2/10 (a London business-to-business bulk supplier with little published lab paperwork, thin independent reputation, no published prices and no escrow). The article also explains that no research peptides are manufactured in the UK, so every UK supplier sources from abroad, and the real question is whether a seller is honest about it. For research purposes only.

## Editorial method

- We list strengths and watch-outs against verifiable signals, and where a review is scored we publish the score out of ten and the framework behind it.
- Every finding sources to a public record (Companies House, ICO register, UKAS register, Trustpilot) or to a direct observation from the supplier's own site or correspondence with the editorial desk.
- The buyer's own priorities decide which signals matter most, but payment protection and a verified certificate of analysis are weighted highest because they are the hardest to recover from if missing.
