These documents are reviewed internally and displayed as they become available. Independent third-party testing is also performed on select lots to confirm identity, purity, and alignment with our internal specifications. --- ## Important Notice This product is intended for laboratory research use only. It is not intended for human or veterinary use, and must not be used for diagnostic, therapeutic, or clinical purposes. This material is not a drug, medical device, or dietary supplement, and has not been evaluated by the U.S. Food and Drug Administration. --- ## Quality & Manufacturing We source materials from vetted domestic and international partners. Each partner follows quality systems aligned with ISO and cGMP principles. Each supplier is reviewed for reliability, documentation integrity, and transparency in testing. We require a verified purity of 99% or higher and perform independent third-party spot testing to confirm that select lots meet our internal standards for identity, purity, and composition. Where available, endotoxin results are listed on the COA to verify laboratory purity. These results are for research quality only. They do not imply suitability for human or veterinary use. All research materials are sealed for integrity and packaged for stability during storage and transport from manufacturing through final delivery. ## Additional information | Weight | 0.0625 lbs | | --- | --- | ### Certificate of Analysis Every batch undergoes independent third-party laboratory analysis to verify identity, potency, and safety.

This method is designed to maintain product integrity and allows vials to remain stable during shipping for approximately 3–4 months. Once a vial is reconstituted with bacteriostatic water, it should be stored in the refrigerator to help maintain stability. Under these conditions, reconstituted material is generally considered stable for up to 30 days. Lyophilization is a dehydration technique in which compounds are frozen and then exposed to low pressure. The water in the vial sublimates — going from solid to gas. What remains is a stable, crystalline white solid. This powder can be kept at room temperature until reconstitution. Upon receipt, products should be stored away from heat and light. For short-term use, refrigeration at approximately 4°C (39°F) is suitable. For long-term storage (several months to years), vials may be placed in a freezer at approximately -80°C (-112°F). Freezing is the preferred method for preserving product stability over extended periods. ⚠️ **Important Notice:** These products are intended for research use only. Not for human consumption. ## Related products - [![PT-141 10 mg research vial -- bremelanotide melanocortin receptor agonist studied in sexual-function research.](https://researchvials.com/wp-content/uploads/2025/08/85.YPB_.274-1000x1000.png)](https://researchvials.com/product/pt-141-10mg/) ## [PT-141 (10mg)](https://researchvials.com/product/pt-141-10mg/) $29.95 [Add to cartLoadingDone](/product/8x-blend-l-carnitine-20mg-l-arginine-20mg-methonine-25mg-inositol-50mg-choline-50mg-b6-25mg-b5-5mg-b12-1mg/?add-to-cart=1455) - [![BPC-157 5 mg research vial -- pentadecapeptide studied for tissue repair and gut lining support.
