One real page, before you commit.
Storage stability windows aren’t intuitive — lyophilized peptides last orders of magnitude longer than reconstituted ones, and the difference between fridge and freezer matters more than people assume.
This table appears on page 08 of the handbook. The rest of chapter 02 explains what changes the windows, what to do if your fridge cycles, and how to verify storage damage.
Storage stability windows
Typical research peptides, indicative working windows from peer-reviewed stability literature.
| Storage temperature | Lyophilized (sealed) | Reconstituted in BAC water | Source class |
|---|---|---|---|
| −20 °C (frozen) | 18–24 months | 4–6 weeks | Pharm. Sci. lit. |
| 2–8 °C (fridge) | 12–18 months | 14–28 days | USP-NF + J. Pharm. Sci. |
| 20–25 °C (room) | 1–3 months | 24–72 hours | Stability bracketing data |
Notes — Windows assume single-vial storage, no freeze-thaw cycling, intact lyo cake. Reconstituted peptides degrade non-linearly above 4 °C. Always defer to the batch-specific shelf life on your COA.
The reconstitution calculator, embedded right here.
Pick the peptide, the vial size, and the target concentration. Read off the bacteriostatic water volume. Same tool we link from every product page.
Two answers, no spreadsheet required.
For the two questions that come up weekly: how long does this vial last, and how many IU am I actually working with.
How long is this vial good for?
Pick the storage state and temperature. Output is an indicative working window from peer-reviewed stability literature.
Averages from the published literature. Always defer to the batch-specific shelf life on your COA.
Vial milligrams to international units.
Enter the vial size in milligrams and pick the IU-per-mg ratio for your peptide class. Output is the total IU available in the vial.
Reference ratios. The exact ratio for your batch is on the COA — defer to it. Pen-click dosing depends on your specific injection device.
Six things people ask before subscribing.
If your question isn’t here, reply to the handbook email and we’ll add it.
Is this really free?
Yes. We make our money on peptide sales, not on selling research material — the handbook is free because we’d rather researchers who order from us know how to handle the product properly. No paywall, no credit card.
What does ‘research use only’ mean in Canada?
RUO peptides aren’t regulated by Health Canada as drugs. They’re sold for laboratory research and methodology work — not for human consumption, in vitro diagnostic use, or therapeutic application. Suppliers don’t need a DEL and buyers don’t need a prescription.
The handbook has a full chapter on what stays inside the RUO envelope and what to keep documented if you’re working in an institutional setting.
How often will you email me?
Once for the handbook delivery (within a minute of subscribing). After that, expect roughly one email per month — covering new peptides we’ve added to the catalog, handbook revisions, and the occasional research update. One-click unsubscribe in every email.
Why do I have to give my email at all?
Because we revise the handbook quarterly and want to send you the updated version when new stability data is published or new peptides are added. Without an email there’s no way to keep your copy current. We also use email to verify you’re a real human, not a scraper.
Where can I see the catalog?
After subscribing, the catalog link opens in a new tab on this page — we don’t redirect you. You can also reach it any time at peptigopeptides.com. We carry 40+ research peptides with third-party lab reports verifiable on Janoshik.
Do you ship outside Canada?
No. Canada only. Cross-border shipping of research peptides involves customs, regulatory variability, and unpredictable cold-chain exposure. Staying domestic keeps things clean.
Recent revisions — this isn’t a static PDF.
Updated quarterly as new methodology or stability data is published. Subscribers get every revision automatically.
Free. About a minute to your inbox.
