Research Peptides UK
Research peptides, documented by batch, not by promise.
Titeris supplies research-use-only peptides: BPC-157, TB-500, GHK-Cu and a small, focused catalogue beyond them. We publish the actual supplier batch documentation against every listing, including the numbers that aren't flattering. We're a new UK supplier. Below is exactly what that does and doesn't mean, in plain terms, not marketing language.

What "documented by batch" actually means here
Most research-peptide sites show you one certificate and let you assume it covers everything you might order. Some don't show you anything at all beyond a purity percentage typed into the product description. We don't do either of those things, and we're not going to imply we do something we don't. Here is the plain version of where our documentation currently comes from, what it covers, and where it's going.
Titeris does not yet operate its own laboratory testing. The batch documentation we publish today comes from our supplier's own third-party testing, attributed to that lab by name, not presented as work we did ourselves. That documentation typically covers identity and purity by HPLC, and where a compound is sold as a blend, the confirmed quantity of each component. It does not cover sterility, endotoxin load, or heavy-metal screening unless a specific listing says otherwise. We're not going to let a purity figure imply more than it actually tells you.
If a batch has no current documentation attached, the product page says so directly instead of leaving the gap unexplained or burying it in small print. We would rather a listing look less finished today than have it quietly imply something we can't back up.
We're not going to tell you this is independently re-verified until it actually is. Building an independent, batch-level re-test process is a real operational step, not a line of marketing copy, and we'd rather under-claim now than have to walk a claim back later. That's a mistake other sellers in this exact category have made publicly, after advertising a "verify it yourself" mechanism that turned out not to work once buyers actually tried it. We're not going to repeat it.

Catalogue
We're launching with a focused catalogue rather than the eighty-plus compounds some suppliers list on day one. Each of these is a compound our own market research found real, sustained UK research interest in, and each one is small enough a set that we can document it properly rather than spread thin across a list nobody could realistically keep current. We'll expand the range as documentation catches up with demand, not before.
BPC-157, 5mg
A 15-amino-acid research compound derived from a gastric-juice protein, studied mainly in animal models for tissue-repair and gut-lining signalling.
£17.99 ViewTB-500, 5mg
A synthetic Thymosin Beta-4 fragment, studied for cell-migration and tissue-repair signalling in animal models.
£24.99 ViewBPC-157 + TB-500 blend, 20mg
The two compounds above, combined in a single vial at a genuine blend price, not five single vials sold together under a bundle label.
£64.99 ViewGHK-Cu, 50mg
A copper-binding tripeptide studied in dermal and connective-tissue research contexts.
£19.99 ViewFull catalogue, including CJC-1295, Ipamorelin, Tesamorelin, Semax and Selank, is on the shop page, each with its own documentation status stated plainly.
Why we built this the way we did
Anyone who has spent time in UK peptide forums or research-chemical subreddits has read the same complaint over and over: a vendor's certificate looks great, right up until someone actually checks the batch number against what shipped, or asks what a supposedly "high purity" figure was even measured against. That pattern is the entire reason this catalogue is small right now instead of large. It's easier to write eighty confident product pages than to genuinely stand behind eighty products.
We say what we don't know
If a compound hasn't been tested this batch, the listing says so. If human safety data doesn't exist for a compound, and for research peptides it usually doesn't, we say that too, instead of quietly implying otherwise. A stated limit is more useful to you than a confident guess.
One document set, one batch code
A single certificate covering an entire product line tells you almost nothing about the specific vial in front of you. Ours are matched to the batch you're actually buying, or the listing tells you plainly that they aren't yet.
Research framing, held to consistently
Every listing here is for laboratory research use. We don't write around that with wellness language, and we don't imply a use these compounds aren't sold for. It's a slower way to write copy. It's also the honest one, and it's the only framing that's actually accurate under UK law.
Frequently asked
Is it legal to buy research peptides in the UK?
Yes, with an important distinction. Research peptides like BPC-157 and TB-500 aren't controlled under the Misuse of Drugs Act 1971, and it's legal to buy, sell and possess them as research-use-only laboratory materials. What isn't legal is marketing or selling them for human consumption, medical treatment, or therapeutic use, which falls under the Human Medicines Regulations 2012. That's exactly why every listing on this site is framed strictly as a research material, never as a treatment. In April 2026 the MHRA confirmed it is actively looking at businesses that blur this line, so we're deliberate about staying well inside it. Full detail, including the specific regulations, is on our legal status page.
Do you independently test every batch?
Not yet. Today we publish our supplier's own third-party documentation, credited to the lab that produced it. We're not going to claim independent in-house testing until we've actually built that process — see the documentation section above for the full, current answer.
What does "research use only" actually mean?
It means the compound is sold as a laboratory material for research applications, not for human or veterinary use, and it hasn't gone through the clinical trial and regulatory approval process that a licensed medicine has. It's not a legal loophole we invented — it's the standard, correct classification for this entire product category in the UK.
How is Titeris different from other UK peptide sellers?
Most of the honest answer is in the sections above: we match documentation to the specific batch instead of reusing one certificate, and we say plainly when a batch doesn't have documentation yet rather than leaving a gap unexplained. We don't claim to be the cheapest, and we're not going to inflate customer counts or invent a "clinically proven" claim to compete on hype instead of substance.
What's in the BPC-157 + TB-500 blend, exactly?
10mg of BPC-157 and 10mg of TB-500 in a single vial. It's sometimes called the "Wolverine Stack" in community shorthand, a nickname we didn't invent and don't use as our own product name. It's priced as a genuine combined product, not as two single vials with a discount label stuck on top.
