BPC-157/TB-500 Spray combines two separate research peptides in one spray-dispensed container. BPC-157 is the 15-residue sequence GEPPPGKPADDAGLV, formula C62H98N16O22, about 1419.5 g/mol, CAS 137525-51-0. TB-500 here is the 7-residue fragment Ac-LKKTETQ, formula C38H68N10O14, about 889 g/mol, CAS 885340-08-9, a market name suppliers sometimes apply inconsistently, so its identity should be checked independently rather than assumed. Veracue supplies 5 mg of each peptide or 10 mg of each peptide, strictly for laboratory research use only.

BPC-157/TB-500 Spray is Veracue's spray-dispensed packaging of two distinct synthetic peptides, BPC-157 and TB-500, offered together as a single listing. Each peptide is also documented on its own BPC-157 Spray listing and TB-500 Spray listing, and the molecular identity reported here is identical to what is reported there.
"Spray" in this product's name is a packaging and dispensing descriptor only. It does not establish a route, a concentration or a formulation for either peptide, and none of those specifics should be inferred from the name. Chemical form, concentration, ratio between the two peptides, fill volume and storage conditions are reported on each lot's own documentation and can be requested through the contact page.

Identity values are drawn from chemical databases for each reference molecule and are not a Veracue lot result.
Purity, chemical form, concentration and lot results for each peptide are reported on each lot's own documentation and can be requested through the contact page.
Veracue also lists BPC-157 and TB-500 individually, each in its own spray format, for research groups that only need one of the two materials. This combination listing exists for research groups tracking both peptides together, with lot records, images and documentation specific to the combined packaging a researcher actually ordered.
This listing combines two chemically unrelated peptides. The reference values below describe each molecule on its own and are identical to the values reported on the BPC-157 Spray listing and the TB-500 Spray listing.

No. Packaging two peptides into one listing does not change the sequence, formula or mass of either compound. BPC-157 and TB-500 remain exactly as documented on the BPC-157 Spray listing and the TB-500 Spray listing; what differs on this listing is that both are supplied together.
"TB-500" is a market name rather than a formal chemical designation, and it has been applied inconsistently across suppliers: sometimes to the short Ac-LKKTETQ fragment described above, and sometimes to material described using full-length thymosin beta-4 data, a separate 43-residue protein with its own mass of roughly 4,963 g/mol. The name alone does not confirm which material a given product contains. Veracue's TB-500 refers specifically to the Ac-LKKTETQ fragment identified above, and that identity should be checked against a lot's own documentation rather than assumed from the name.
BPC-157 does not carry this same naming ambiguity: its sequence, formula and CAS number are consistent across standard chemical database records.
In Veracue's catalog, "Spray" is a packaging and dispensing term, comparable to "vial" or "powder" on other listings. It tells a researcher how the product is dispensed from its container. It does not specify a concentration, a ratio between BPC-157 and TB-500, a carrier or a route, and it is not shorthand for any particular method of use. Those details, where applicable, live in lot-specific documentation rather than in the catalog name.
A two-peptide listing makes this distinction more important, not less: a packaging word says nothing about how much of each peptide a given unit contains relative to the other. A researcher documenting materials in a methods section should cite the lot's own documentation for format-specific details rather than inferring them from the word "Spray."
Both names are used loosely across suppliers and reference sources, which makes it hard to know exactly what a listing describes.
Anchor on identifiers rather than names alone: BPC-157 is GEPPPGKPADDAGLV, C62H98N16O22, CAS 137525-51-0. TB-500 here is Ac-LKKTETQ, C38H68N10O14, CAS 885340-08-9. Stated together, each set of identifiers describes a specific molecule, and both should be checked against a lot's own documentation.
Researcher takeaway: Ask which sequence, which formula and which CAS number a listing is actually using for each peptide.
The two names are sometimes used interchangeably in the broader market, which can suggest they are the same material.
No. Full-length thymosin beta-4 is a naturally occurring 43-residue protein weighing roughly 4,963 g/mol. TB-500 as supplied here is the much smaller Ac-LKKTETQ fragment, about 889 g/mol. They are related by sequence overlap, not identity, and findings for one should not be assumed to apply to the other.
Researcher takeaway: Confirm which of the two materials a record actually describes before comparing data.
A combined listing can read as though it contains a new or different material from the individual listings.
No. Both peptides in this listing carry the same sequence, formula, CAS number and PubChem CID reported on the BPC-157 Spray listing and the TB-500 Spray listing. The difference is packaging: this listing supplies both peptides together rather than as two separate purchases.
Researcher takeaway: Treat the combination as shared packaging of two already-documented molecules, not a new compound.
A certificate of analysis documents one lot, never a packaging format or a compound in general. For a two-peptide listing like this one, look for each item below to cover both BPC-157 and TB-500, because a result for one component says nothing about the other.
| COA item | What it helps establish |
|---|---|
| Lot number | Which production run the results describe. It should match the container and the order record for the unit received. |
| Peptide names, sequences or formulas | Whether the record names both BPC-157 and TB-500 and ties each to its own sequence. |
| Chemical form | Free peptide, acetate or another salt, for each component separately. |
| Identity result | Expected and observed mass for each peptide, with the method used, for example LC-MS or ESI-MS. |
| HPLC or other purity method | Analytical purity under stated conditions, reported for each peptide. |
| Test date and laboratory | Establishes when testing occurred and who performed it. |
Which fields appear varies by supplier and by lot, so check the specific document rather than assuming a standard set of tests was run. No purity figure, HPLC result or mass-spectrometry value is stated on this listing, since none is lot-specific until a given batch is tested. If a lot-specific certificate is available, use it as the primary source for that lot's reported results. The certificate page explains how to request lot documentation.
Because this listing holds two peptides, a full identity check has two parts. BPC-157 should be matched to C62H98N16O22, average mass about 1419.5 g/mol, CAS 137525-51-0. TB-500 should be matched to C38H68N10O14, average mass about 889 g/mol, CAS 885340-08-9. A record confirming only one of the two leaves the other unverified.
| Component | Reference mass | Formula |
|---|---|---|
| BPC-157 | About 1419.5 g/mol | C62H98N16O22 |
| TB-500 (Ac-LKKTETQ fragment) | About 889 g/mol | C38H68N10O14 |
A mass spectrometer detects ions, not spray bottles. A peptide can carry one or more charges, so one molecule can show up at several m/z values, and observed signals will not match the molecular weight on a data sheet directly. Adducts and counterions can shift or add signals. The two reference masses here, about 1419.5 and about 889 g/mol, sit far enough apart that their signals should not be confused, and interpretation belongs to the analytical record and its stated method conditions.
No. The verification question is the same for either listing: does this lot match the stated molecules, and is each purity figure paired with a mass result from that same lot. Combining two peptides into one listing does not change what counts as adequate documentation for each one.
Ask the Veracue team about available documentation for a specific lot, or review the certificate library.
