Storage and handling
Store cold
Sealed vials at 2 to 8 °C (36 to 46 °F), protected from light, as printed on the label. Freeze at −20 °C for long-term storage.
Warm before opening
Let cold vials reach room temperature to prevent condensation on the powder.
Keep sealed
Store in the original sealed vial, dry and away from light, until the material is needed.
More detail in our storage and handling guide.
Questions
Which salt form is BPC-157 supplied as?
Acetate, the standard counter-ion after purification. The counter-ion for each lot is stated on its certificate of analysis.
Does BPC-157 ship with a certificate of analysis?
Yes. Every lot is tested for identity by mass spectrometry and purity by HPLC before release. The lot number on your vial matches its COA in our COA Library.
How should BPC-157 be stored?
Keep sealed vials refrigerated at 2 to 8 °C (36 to 46 °F) and protected from light, as printed on the label. For long-term storage, freeze at −20 °C. Let a cold vial reach room temperature before opening. See our storage guide.
Does BPC-157 come with syringes or needles?
No. RWP Laboratories does not sell or supply syringes or needles, and does not provide usage instructions.
