02Verify your vial
Every vial label carries a QR code. Point your phone camera at it.
The code opens that lot's certificate with every assay value. No phone? Type the lot from your packing slip on Verify a lot.
Each signed certificate links to the lab's own verification page, so the report can be confirmed independently of us.

Components
Each component is confirmed separately on the lot certificate.
TB-50010 mg · 43 residues
KPV10 mg · 3 residues
BPC-15710 mg · 15 residues
Each component is built from its own sequence with ideal bond lengths and angles, so every connection is exact. They are separate molecules in the vial, not bonded to each other; the stack is for viewing only. Poses are idealised, not measured conformations. Each component is confirmed separately on the lot certificate.
Structure viewer04In the lab
In laboratory research BPC-157 is studied for vessel growth and tendon cell migration, TB-500 for cell migration, and KPV for NF-kB signaling in gut cells. No paper has tested all three; a tendon repair study pairing BPC-157 and TB-500 saw no gain over either alone.
Blend
TB-500 / KPV / BPC-157Blend of BPC-157, TB-500 and KPVCell survival
Endpoint studied
Formed a complex with PINCH and ILK that activated Akt; heart muscle cells migrated and survived more.
Bock-Marquette 2004 · PMID 15565145Gut cell signaling
Endpoint studied
Taken up through PepT1; nanomolar KPV lowered NF-kB and MAP kinase activation and cytokine secretion.
Dalmasso 2008 · PMID 18061177Vessel growth
Endpoint studied
Higher vessel density, more endothelial tube formation and faster blood-flow recovery.
Hsieh 2017 · PMID 27847966Pathways as reported in the cited laboratory studies, for each compound in the blend. For in-vitro research use only.

5 milestones, each linked to its PubMed record
TB-500 · Proceedings of the National Academy of Sciences of the United States of America
The 43-amino-acid sequence of thymosin beta 4, isolated from thymus, is determined; its N-terminus carries an acetyl group.
PubMed · PMID 6940133KPV · Peptides
Lys-Pro-Val, alpha-MSH residues 11 to 13, lowers fever in a pyrogen model, though less potently than the full hormone.
PubMed · PMID 6333677TB-500 · The Journal of Biological Chemistry
Fx, the peptide holding unpolymerized actin in platelets, proves identical to thymosin beta 4 and forms a 1:1 complex with actin monomers.
PubMed · PMID 1999398BPC-157 · Journal of Physiology, Paris
A protective peptide isolated from human gastric juice is reported, with BPC 157, the 15-amino-acid fragment thought to carry its activity.
PubMed · PMID 8298609BPC-157 + TB-500 · Joint Diseases and Related Surgery
A tendon repair model tested BPC-157 plus TB-500: the pair improved tendon structure but added nothing over either peptide alone.

Email [email protected], Monday to Friday. A person replies within one business day.
The current released lot, SA-TB1-2610. Scan the QR code on the vial label to open its certificate. The lot number is also on your packing slip, and the full certificate is here.
Every certificate is issued by an independent laboratory. Each lot has its own public record page with every assay value, and a link to verify the report on the lab's own site once the signed PDF is posted.
Vials are filled slightly over the labelled mass so that every vial meets it. Net content is measured on each lot and published as a number, not a pass.
Email [email protected] within 7 days with your order number and a photo and we will replace it.
Orders by 2 PM ET on a weekday ship the same day, with tracking emailed when the label prints.
