How to Use This Chart
This reference covers the 20+ most popular peptides. For each compound, we list:
- Lyophilized storage: Temperature for unreconstituted (powder) vials
- Reconstituted shelf life: How long the mixed solution lasts when refrigerated with BAC water
- Light sensitivity: How critical light protection is for this specific compound
All reconstituted peptides should be stored at 2-8°C (36-46°F) — standard refrigerator temperature. The differences between peptides are mainly in long-term powder storage, reconstituted shelf life, and light sensitivity.
Universal Rules: (1) Never freeze reconstituted peptides. (2) Always use BAC water unless otherwise specified. (3) Store in an opaque case to eliminate light exposure. These apply to every peptide on this list.

Quick Reference Rules
If you can't remember the specifics for your peptide, these universal rules will keep you safe:
- Powder goes in the freezer (-20°C) for long-term storage. Fridge (2-8°C) is fine for up to 6 months.
- Reconstituted goes in the fridge (2-8°C). Never freeze reconstituted peptides.
- Use BAC water. It extends shelf life from days to weeks.
- 4 weeks is a safe maximum for any reconstituted peptide in BAC water. Some last longer, but 4 weeks is the conservative, safe cutoff.
- Treat all peptides as light-sensitive. Even "moderate" light sensitivity means degradation over weeks. An opaque case eliminates the variable entirely.
- Back of the middle shelf. The coldest, most stable part of your fridge.
Pro Tip: Screenshot this chart or bookmark this page. When you add a new compound to your protocol, check the chart for any compound-specific considerations before you reconstitute.
Why Storage Matters More Than You Think
Here's the math: a typical peptide protocol costs $100-$500 per month in compounds alone. Improper storage that causes even 20% potency loss means you're effectively throwing away $20-$100 per month. Over a 6-month protocol, that's $120-$600 wasted.
A proper storage case costs $17-$35. It pays for itself on the first vial it protects. Every vial after that is pure savings.
Bottom Line: Every peptide on this chart needs cold, dark, and organized storage. The specifics vary slightly by compound, but the solution is universal: a proper storage case in the back of your fridge. Bookmark this chart, follow the universal rules, and your compounds will stay potent through every protocol.
