Peptide appearance
Lyophilized form helps protect peptide quality. Peptides are supplied as a dry powder, which may look like a compact "puck" or a lighter powder inside the vial.
Because the peptide is dry, it does not require refrigerated shipping during normal transit, including warm seasonal conditions. For longer storage, follow the storage guidance in the product description.
Appearance can vary. The stated peptide content is checked through third-party analysis.

Solution not bundled
Peptides are delivered as lyophilized powder. This dry form helps preserve peptide quality during storage and transport and does not require refrigerated shipping during normal transit.
To prepare a solution, use a solvent such as Bacteriostatic water. It is sold separately, so add it only when you need it for peptide preparation.

BPC-157 and TB-500 blend for paired tissue-signalling and cell-migration studies.
Research overview
BPC-157 / TB500
BPC-157 / TB500 combines two separately described peptide research materials in one vial.
The blend should be interpreted component by component for identity, sequence, and analytical documentation rather than as a new single compound. The listed sources are a research starting point rather than a substitute for product evidence: the supplied material's exact form, lot, and measured characteristics must be established through its signed analytical record.

Laboratory care
Handling
Peptides in transport
Peptides in lyophilized form are supplied in glass vials by standard shipping methods and do not require refrigeration. Short-term temperature fluctuations during transport will not reduce their quality and efficacy. Even at high summer temperatures, the peptides in lyophilized form are stable for several weeks.
Storage of lyophilized peptides
Lyophilized peptides should be stored in a dry place, protected from light and moisture. The following storage conditions are generally recommended:
- Room temperature (15–25 °C): Up to 3 months
- Refrigerated (2–8 °C): Up to 6 months
- Frozen (-20 °C or below): 3–5 years (recommended for long-term storage)
Allow the vial to reach room temperature after taking it out of the refrigerator or freezer.
Storage of reconstituted peptides
Once reconstituted, peptide solutions are generally less stable than their lyophilized form and should be stored under refrigerated conditions whenever possible.
The following storage conditions are generally recommended:
- Room temperature (15–25 °C): Avoid prolonged storage
- Refrigerated (2–8 °C): Typically 4–8 weeks
- Frozen (-20 °C or below): Up to 3–4 months
To preserve peptide integrity, avoid repeated freeze–thaw cycles, as these may accelerate peptide degradation.
Important: Most manufacturers recommend discarding reconstituted peptides within 4 weeks when stored at 2–8 °C. This recommendation is intentionally conservative and may not reflect the actual chemical stability of every peptide. In our own stability studies, many peptides reconstituted in bacteriostatic water showed no detectable degradation after 12 weeks of refrigerated storage. As peptide stability is highly sequence- and formulation-dependent, this result should not be extrapolated to all peptides without supporting stability data.
