Peptide Care Guide

1. Storage Before Reconstitution

  • Store all lyophilized (powdered) peptides in a cool, dark, dry place, like a drawer or cabinet away from heat and light.

  • For long-term preservation, keep vials refrigerated at 2–8°C

  • Avoid direct sunlight and temperature fluctuations.

    Tip: Long-term storage (over several months) is best in a freezer at –20°C.


2. Reconstitution

  • Use only sterile Bacteriostatic Water (BAC Water) when reconstituting peptides.

  • Gently inject the water down the side of the vial, avoiding direct pressure on the powder.

  • Allow the peptide to dissolve slowlydo not shake or swirl aggressively.

  • Discard opened BAC Water after 14-21 days
    Use clean syringes and alcohol pads during handling to maintain sterility.

3. After Reconstitution

  • Once peptides are reconstituted, they become more sensitive to temperature, light, and contamination.
  • Store all reconstituted peptides in the refrigerator (2–8°C).
  • Do not freeze after reconstitution — ice crystals can damage the peptide structure.
  • Keep vials away from light and open only when necessary.
  • For best results, use within 30 days of reconstitution.
  • If the solution appears cloudy, discolored, or has particles, discard it immediately.

4. Handling Tips

  • Always wash hands thoroughly before handling peptides.
  • Work on a clean, disinfected surface in a low-dust environment.
  • Wipe vial tops with an alcohol pad before and after each use.
  • Use a new, sterile syringe each time — never reuse needles or BAC water.
  • Avoid shaking vials; instead, gently swirl if mixing is needed.
  • If a vial is accidentally contaminated or left unrefrigerated for a long period, discard it to ensure research accuracy.
