Can you mix multiple peptides in the same vial?

Mixing peptides in the same vial is generally not recommended due to potential chemical interactions between different amino acid charges, pH incompatibilities, and stability concerns. Some peptides like CJC-1295 (no DAC) and Ipamorelin may be drawn into the same syringe immediately before injection, but should not be stored together. GLP-1 receptor agonists, depot formulations, and peptides with unknown compatibility profiles should always be administered separately to maintain their pharmacological integrity.
