What does the research on BPC-157 investigate?
BPC-157 is a synthetic pentadecapeptide whose sequence, GEPPPGKPADDAGLV, has an unusual composition: nine of its fifteen residues are glycine or proline, and it contains no cysteine, no methionine and no tryptophan. That matters far more than it sounds. The three residues absent from the chain are the ones responsible for most peptide instability - cysteine forms unwanted disulfides, methionine and tryptophan oxidise - so a sequence without them is comparatively robust and its purity trace is comparatively clean. The other consequence is polarity: a chain dominated by glycine and proline is very hydrophilic, retains poorly on a standard reversed-phase method, and is often more comfortably handled with an ion-pairing reagent or an alternative stationary phase. The published literature on this sequence is laboratory work in cell and tissue models. This page describes the material and its documentation only.
Who can buy BPC-157?
BPC-157 is supplied strictly as a research chemical for in-vitro laboratory research. Products are sold exclusively to qualified researchers and licensed laboratories.
At checkout the buyer confirms that they are 18 or over, are buying in the course of research, and are responsible for handling, storing and disposing of the material in line with their laboratory's procedures. BPC-157 is not for human or veterinary use.
We only answer questions about specifications, documentation and orders.
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.

Frequently asked questions
Why is BPC-157 read at 214nm rather than 280nm on a purity trace?
The sequence has no tryptophan, tyrosine or phenylalanine, so it has essentially no absorbance at 280nm. Purity is therefore recorded from peptide-bond absorbance near 214nm, and the wavelength is stated on the batch record.
What does the run of prolines mean in practice?
Positions three to five are all proline, which stiffens that segment and can produce cis/trans isomer peaks on a slow gradient — a known behaviour of the sequence, not a purity problem.
Which salt form is BPC-157 supplied as?
Synthetic peptides are isolated as salts; the counterion travels with the peptide into the vial and is recorded on the batch documentation. Check the form before the material goes into sensitive assays.
Is BPC-157 supplied for human or veterinary use?
No. BPC-157 is supplied as a lyophilised powder in a sealed vial and is supplied strictly as a research chemical for in-vitro laboratory research. Products are sold exclusively to qualified researchers and licensed laboratories, and buyers confirm they are 18 or over and purchasing in the course of research. We only answer questions about specifications, documentation and orders.
How is the purity figure measured, and what does it actually tell me?
Purity is measured by reversed-phase HPLC at an independent laboratory, and the result is published with the method conditions rather than as a bare percentage. The figure is the proportion of the UV-absorbing material in the chromatogram that elutes as the target peak. It describes the sample as analysed; it is not a statement about what the material is for. A high figure alongside a clean chromatogram is the useful combination, which is why the report is worth reading rather than the headline number alone.
What documentation comes with a batch?
Each released lot carries a number printed on the vial label and a report stating purity by RP-HPLC, measured content against label, and the testing laboratory. Reports published so far are listed on this page and collected on the certificate hub, and each carries a lot number that can be checked against the vial in front of you. Where a report is not yet published for a listing, ask before ordering and we will send the documentation that exists for the lot being shipped.
How should BPC-157 be stored?
In the form supplied, as a lyophilised powder, the material is stable kept cold, dry and dark. For powder, that means a freezer at around minus 20 degrees Celsius, desiccated, with the vial sealed and shielded from light, which is how it should stay until you are ready to work with it. Bringing a vial to room temperature before opening avoids condensation on the contents. Once in solution the material is less stable than the powder and should be kept cold and used within a short working window. Choosing a solvent and storage conditions for your own work is your call, not ours.
Do I need bacteriostatic water to prepare it?
A lyophilised powder needs a solvent added before it can be worked with. Bacteriostatic water, which is water with 0.9% benzyl alcohol, is the common choice because the preservative extends the working life of the solution once the vial has been opened, and we supply it in 3ml and 10ml vials. It is not the only option: where a method cannot tolerate benzyl alcohol, use the solvent the method specifies. The choice affects the sample, so it belongs to the researcher.
How and when is an order shipped?
Orders are dispatched from the United Kingdom. An order placed before 4pm on a working day is collected the same day; weekends and bank holidays roll forward to the next working day. UK orders go by tracked DPD next-day delivery, free on orders over 14 pounds and 4.99 pounds below that. Tracking is sent when the parcel is collected, so the first scan is usually visible the same evening.
Why is BPC-157 less prone to degradation than many peptides?
Because of what its sequence does not contain. Cysteine, methionine and tryptophan are the residues that drive most peptide instability - cysteine by forming disulfide bridges between chains, methionine and tryptophan by oxidising - and BPC-157 has none of them. What remains is a chain dominated by glycine and proline, both of which are resistant to the processes that degrade peptides in storage. That is a statement about molecular stability.
Why does it elute early on a reversed-phase column?
Because it is very polar. Reversed-phase retention depends on how hydrophobic a molecule is, and a chain where most residues are glycine or proline has little hydrophobic character to hold it on the stationary phase. A short retention time is the expected result for this sequence. Where a method needs more retention, the usual approaches are ion pairing or a different column chemistry rather than a longer gradient.
What does the published research on this sequence examine?
Largely work in cell and tissue models, alongside studies on how the peptide behaves in simple buffer systems. That literature is where the compound is described, and it is not a description of anything this supplier claims or offers. This material is supplied for laboratory research only.
What is the difference between the 5mg and 10mg vials aside from quantity?
The material is the same, drawn from the same production process. The difference is the number of experiments one vial can support and how many lot numbers a programme spans. At 1419.6 g/mol, five milligrams is roughly three and a half micromoles, which suits a short characterisation series, while ten milligrams is better matched to work that would otherwise need a second vial partway through.
