Safety & Handling Protocols

Peptides are fragile biological compounds. Improper handling, storage, or reconstitution can render them inactive or, worse, lead to contamination.

1. Proper Storage

Lyophilized (Powder): Keep in a cool, dark place. For long-term storage (over 3 months), a freezer at -18°C up to -20°C is recommended. Short-term storage can be in a refrigerator at 2-8°C.

Reconstituted (Liquid): Once mixed, peptides are highly unstable. They MUST be refrigerated and used within their stability window (typically 3-4 weeks for most compounds).

Aesthetic Tip: Never shake a reconstituted peptide. Shaking causes mechanical stress that can break the delicate peptide chains. Gently swirl instead.

2. Sterile Reconstitution

Always use Bacteriostatic Water (water with 0.9% benzyl alcohol) to prevent bacterial growth. Sterile water is only suitable for single-use vials.

  • Sanitize vial stoppers with 70% Isopropyl alcohol before every entry.
  • Use a sterile syringe to inject water slowly down the side of the vial.
  • Allow the powder to dissolve naturally; do not force it.

The “Cold Chain”
Importance

Peptides are heat-sensitive. Most vendors ship with ice packs, but the real clock starts when you receive them. Understanding the degradation curve is vital for research efficacy.
