BPC-157 and TB-500 are two of the most frequently referenced research peptides. This page compares them by origin, structure, and research focus โ strictly as laboratory reference compounds. It is not a recommendation, and contains no dosing, usage, or therapeutic claims.
At a glance
| Attribute | BPC-157 | TB-500 |
|---|---|---|
| Type | Synthetic pentadecapeptide (15 amino acids) | Synthetic peptide fragment |
| Origin of sequence | Partial fragment of a protein found in gastric juice | Active fragment of thymosin beta-4 (Tฮ4) |
| Research focus in literature | Connective-tissue and gastrointestinal research models | Connective-tissue and cell-migration research models |
| Form supplied | Lyophilised powder | Lyophilised powder |

How they differ
The two compounds have different origins and structures: BPC-157 derives from a gastric-juice protein fragment, while TB-500 corresponds to a fragment of thymosin beta-4. In the published literature they appear in overlapping but distinct research contexts. Because both are research-only reference materials, this comparison is limited to what the scientific literature describes โ not to outcomes in humans.
What they have in common
Both are supplied here as lyophilised powders, both are independently third-party tested for purity (HPLC) and identity (MS), and both ship with a batch-matched COA. For handling and shelf-life basics, see the peptide storage guide.
Both, lab-tested and shipped from Canada
HPLC + mass-spec verified with batch-matched COAs and fast tracked Canada-wide shipping.

Frequently asked questions
Is BPC-157 or TB-500 ‘better’?
Neither is presented as better. They are distinct research compounds with different origins and research contexts. We provide reference information only, not recommendations.
Are both compounds lab tested?
Yes โ every batch of each is independently tested for purity and identity, with a batch-matched COA.
Can they be used together?
We provide no guidance on use, combination, or dosing. Both are supplied strictly for laboratory research use only.
For laboratory and research use only. Not for human or veterinary use, consumption, or administration. Nothing on this page is medical advice or a claim that any compound diagnoses, treats, cures, or prevents any condition.
