BPC-157 + TB-500 Blend 20mg

Specification

What does the research on BPC-157 + TB-500 Blend investigate?

This is a two-component blend of BPC-157 and TB-500, ten milligrams of each in a single vial, and the two components are a useful contrast in stability. BPC-157 contains no cysteine, methionine or tryptophan, so it carries none of the usual routes to degradation. TB-500 is a short acetylated fragment of thymosin beta-4 and is similarly free of those residues. The result is a blend with no oxidative liability in either component, which means a purity trace for this material is read almost entirely for synthesis by-products rather than for storage damage - an unusual position for a multi-component product, where the analytical burden is normally the combination of both compounds and the ratio between them. That ratio still has to be established, because the label total is an arithmetic sum and not a statement about either peptide. Nothing here describes a use, benefit, dose or effect in people.

Is BPC-157 + TB-500 Blend legal in the UK?

BPC-157 + TB-500 Blend is not a licensed medicine in the United Kingdom and is not listed in any schedule of the Misuse of Drugs Act 1971. Selling it as a research chemical is a lawful trade; what the law restricts is the purpose it is sold for, not the fact that it is sold.

Three pieces of legislation frame that distinction. The Human Medicines Regulations 2012 make it an offence to sell an unlicensed product for human use. The Psychoactive Substances Act 2016 prohibits supplying a psychoactive substance for human consumption, which is why a research-only basis is not a formality. The Misuse of Drugs Act 1971 would apply only if the compound were scheduled, and it is not. Each of these turns on the purpose of the supply, so the statements on this page are written plainly rather than tucked into small print.

In practice that means a supplier may lawfully sell to a researcher, research organisation or business buying for research, and the buyer confirms at checkout that they are 18 or over, buying in the course of research, and responsible for handling, storing and disposing of the material lawfully. Nothing here is legal advice for your own circumstances; if you need a position, take qualified advice.

Neither component is a licensed medicine in the United Kingdom, and neither is scheduled under the Misuse of Drugs Act 1971.

How are identity and quality assured?

Each released lot is tested and the result is published, rather than the material being described as high purity on the strength of a supplier's word. Purity is measured by reversed-phase HPLC at an independent laboratory. The laboratory used for every lot published so far is Janoshik Analytical, in the Czech Republic, and the result is stated alongside the measured content against label so the two can be read together.

The report carries the lot number printed on the vial, which is the part that matters. A certificate showing a result without a lot number cannot be tied to the vial in front of you, and a certificate for a different lot tells you nothing about yours. Matching the printed number on the label to the number on the report is a five second check and it is the whole point of publishing both.

Identity confirmation by mass spectrometry is a separate test and is ordered as an add-on, so the figures published here come from RP-HPLC purity testing unless a report says otherwise. Where no report is published for a listing yet, the documentation held for the lot being shipped can be requested before you order. We would rather send you what exists than let you assume a certificate is available when it is not.

Synthesis and supply

Peptide material is built by solid-phase synthesis, purified by preparative HPLC, then lyophilised. Lyophilisation freezes the solution and removes the solvent under vacuum, which is why the vial arrives holding a cake or powder rather than a liquid and why a solvent has to be added before the material can be worked with. Removing water also removes the main route by which a peptide degrades in storage, which is the reason the format is used.

Sequence length and modification are what make batches differ in difficulty. Every coupling step is an opportunity for a truncated or deleted by-product, and a heavily modified or long chain presents more of them, which is why the purity trace rather than the headline figure is what a certificate is read for. Vials are filled and labelled with the lot number, and the lot number is what the report and the verification lookup resolve against.

Documentation & batch verification

The current released lot is IP-BPCTB20-001, tested 2026-05-26 by Janoshik Analytical (CZ): measured content TB-500 11.14 mg · BPC-157 11.32 mg, identity Purity confirmed (RP-HPLC). The full report for this lot is published and can be checked online — verify this batch. See the full record for lot IP-BPCTB20-001 or all published certificates of analysis.

Published batch records show the laboratory, report date, purity and measured content where reported. Check the certificate for the exact lot: an HPLC purity result does not establish LC-MS identity, sterility or suitability for human or animal use. Review the published batch record before ordering.
