We do not provide reconstitution instructions or research assistance. The amount of BAC water to add depends on your desired peptide concentration. For personalized research guidance, we recommend using an AI tool such as ChatGPT or Google Gemini.
Our peptides are supplied in lyophilized powder form to maximize stability. When kept in their lyophilized state and not reconstituted, they can be stored at room temperature for 1–2 years without significant degradation. However, once reconstituted, peptides must be refrigerated at 4 °C and are stable for only 1–2 months. Always avoid exposing peptides to direct sunlight.
We do not provide protocols, dosing, or administration guidance. All products are for laboratory research use only and are not for human or animal use.
We also do not offer research advice or instructions. Our support staff cannot provide any research-related guidance or assistance.
We currently ship to all U.S. states except Puerto Rico and military installations.
