Peptide Appearance & Color Guide
Updated April 28, 2026
Overview
Wondering what color your peptide should be after mixing? This guide provides the expected appearance of each peptide and combination stack after proper reconstitution. While most peptides are colorless or clear, a few have a distinct color due to their chemical structure.
If your peptide looks noticeably different than described below, contact support before using it.
Single Peptide Color Reference
Peptide | Appearance After Reconstitution | Notes |
|---|---|---|
5-Amino-1MQ | Orange to amber | Bright orange is expected; this is due to the quinolinium backbone |
GHK-Cu | Blue | Distinct blue color from copper peptide complex |
BPC-157 | Clear | May appear slightly hazy depending on temperature |
TB-500 | Clear | Should remain colorless |
CJC-1295 (with or without DAC) | Clear | Minor foaming or bubbles are normal |
Ipamorelin | Clear | Should remain transparent |
Sermorelin | Clear | Slight haze is okay |
Semax | Clear to slightly cloudy | Minor cloudiness is acceptable |
Selank | Clear to slightly cloudy | May appear slightly milky |
Epithalon | Clear | No visible color |
Thymosin Alpha-1 | Clear | No visible color |
Thymulin | Clear | Should remain colorless |
AOD-9604 | Clear | Transparent appearance expected |
Kisspeptin-10 | Clear | No visible color |
PT-141 (Bremelanotide) | Clear | May foam slightly when shaken |
Tesamorelin | Clear | Use promptly after mixing |
MOTS-c | Clear | Colorless |
Storage Notes
- Reconstituted peptides should be stored in the refrigerator (2–8°C / 35–46°F).
- Discard any peptide that shows signs of cloudiness (if normally clear), discoloration, floating particles, or unusual odor.
- Do not freeze peptides unless explicitly instructed on the label.
Final Note
If you’re unsure about how your peptide should look, or if the color seems off from what’s listed above, please reach out to our support team before using it.
