Getting Started / Injection Basics

Why Peptides Arrive in Powder Form:
Peptides are shipped as a freeze-dried powder (also called lyophilized) to preserve their purity, stability and effectiveness. This powder must be reconstituted using bacteriostatic water before injection.

What You Need to Do:
If this is your first time using peptides, don’t worry — we’ve made it easy for you.
Start by reading the two instructional guides below.

Notes:

  • Always follow proper sterile handling procedures.

  • Store unused peptides (lyophilized powder) in a cool, dark place. They are shelf-stable for up to 2 months at room temperature, or up to 2 years in the freezer.

  • Once reconstituted with bacteriostatic water, peptides should be stored in the refrigerator and used within 30–45 days.

  • Let us know if you need help or have questions about mixing or storage.
