Most research peptides are manufactured and shipped as lyophilized (freeze-dried) powder to maximize stability and shelf life. Reconstitution involves adding an appropriate sterile diluent (typically bacteriostatic water) to create an injectable solution. The volume of diluent added determines the final concentration (e.g., adding 2mL to 5mg powder = 2.5mg/mL). Proper reconstitution technique is critical for accurate concentration and sterility.

Standard reconstitution process: allow refrigerated vial to reach room temperature; draw appropriate volume of bacteriostatic water into syringe; inject slowly down the vial wall (not directly onto the powder); gently swirl (never shake — shaking damages peptide structure through mechanical stress); allow to fully dissolve; store refrigerated. Concentration is calculated as: mg of peptide ÷ mL of added water = mg/mL. For example: 5mg peptide + 2mL BAC water = 2.5mg/mL = 2,500mcg/mL. Critical: use sterile technique throughout.
