BPC-157 Storage & Stability: 10mg Vial Guide

What the Product Listing States

Remy Research lists the ProPeptide BPC-157 10mg vial as freeze-dried (lyophilised) powder in a sealed glass vial. Its listed storage is +2 to +8°C, with the advice to refrigerate it as soon as it arrives and keep it out of the light. The BPC-157 20mg pen is a different format: 20mg already dissolved in 3mL, kept at 2–8°C, out of the light and never frozen.

Orders travel in cold-chain packaging that holds 2–8°C, and Dubai orders placed before 4 PM arrive the same day; the delivery page has the full terms. Where a label and a general guide disagree, follow the label.

Powder Keeps Longer Than Solution

Two widely used peptide-handling guides, from Bachem and Sigma-Aldrich, agree on the main points.^[1][2]

• Powder, long term. Bachem advises keeping freeze-dried peptide in a tightly closed container below −15°C for longer storage, and colder for long-term holding. It also notes that peptides can ship at room temperature and sit in a refrigerator at 4°C for short-term use.^[1] Sigma-Aldrich recommends −20°C for one to two weeks and −80°C beyond that.^[2]
• Solution. Sigma-Aldrich gives peptide solutions in general up to a week at 4°C and calls their shelf life limited. Bachem does not recommend storing solutions long term and advises frozen aliquots.^[2][1]
• Freeze-thaw. Sigma-Aldrich advises against repeated freeze-thaw cycles for both powder and solution, which is why a solution is split into single-use aliquots.^[2]

These are general rules for research peptides, not BPC-157 measurements. The listed +2 to +8°C for the 10mg vial falls within Bachem's short-term refrigerator guidance.

What the BPC-157 Sequence Suggests

BPC-157 is a 15-residue peptide, Gly-Glu-Pro-Pro-Pro-Gly-Lys-Pro-Ala-Asp-Asp-Ala-Gly-Leu-Val (GEPPPGKPADDAGLV). PubChem lists the free base as C₆₂H₉₈N₁₆O₂₂, 1419.5 g/mol.^[3]

The handling guides single out five amino acids. Bachem says peptides containing asparagine, glutamine, methionine, cysteine or tryptophan have limited shelf lives. Sigma-Aldrich notes that cysteine, methionine and tryptophan are prone to air oxidation and that all five make solutions unstable.^[1][2] BPC-157 contains none of them.

That removes the best-known weak points, but it is not a measured shelf life. Moisture, heat and time still degrade any peptide, and an opened vial is exposed to all three.

Stable in Gastric Juice Is Not Shelf Life

BPC-157 is often described as "stable". The word comes from its developers: a 2021 review from the group that first described the peptide states that it is "native and stable in human gastric juice for more than 24 h", citing the group's own earlier work.^[4]

That describes resistance to digestion in their experiments. It says nothing about how a vial of powder or a solution keeps in a refrigerator, and it does not replace the label.

Heat, Light and Moisture in the UAE

• Heat. In the ICH Q1A(R2) stability guideline, a substance meant for refrigerated storage is tested long term at 5°C ± 3°C, and 25°C at 60% relative humidity is already its accelerated, stress condition.^[5] UAE summer temperatures run far above that, so a delivery should go straight into a refrigerator. The general peptide storage guide covers temperature excursions in more detail.
• Moisture. Peptides take up water from the air. Both guides advise letting a cold vial reach room temperature before opening it, Bachem in a desiccator, because absorbed moisture lowers the peptide content and can reduce stability.^[1][2] Keep the vial tightly capped when it is not in use.^[2]
• Light. Store the vial away from bright light, as the product listing and Sigma-Aldrich both advise.^[2]

When the Delivery Arrives

• Check that the box still feels cold and the cooling elements have not warmed up.
• Check that the vial seal is intact and that the label (product, strength and lot) is readable.
• Move the vial to a refrigerator at +2 to +8°C straight away.
• If the box was warm, or the vial spent time outside its listed range, write down how long and how warm. A powder or solution that looks normal is not proof of quality: only a retest, for example by HPLC, shows whether the peptide has changed.

Keep a Storage Record

For a lab notebook or a methods section, record the arrival date and condition, the refrigerator's temperature log, the date the vial was first opened and the lot number on the label. If results drift, that record is what lets a team rule storage in or out.

What This Page Does Not Claim

• It does not give a shelf life for BPC-157 powder or solution.
• It does not give dosing, preparation or administration information.
• It does not present general peptide-handling guidance as data for this product.
• It does not imply a published batch report for the BPC-157 line, which has none at the time of writing.
