Dose logging on your schedule
Set up each protocol once — daily, every N days, or fixed weekdays — then tick off doses as you take them. The plan is yours; Peptly keeps the record.
Built in Germany · Data in the EU
Track your peptide protocols properly.
Peptly is a web app for logging peptide doses, supplements, lab values and body data — built in Germany, with your data stored in the EU (Stockholm).
24 hours of full access · No credit card · Nothing gets charged
Heads-up: Peptly's app interface is fully available in English — switch anytime in Settings. Wiki articles, legal texts and AI answers are in German for now; we say that upfront rather than hide it.
What Peptly does
A logbook, not an advisor
Peptly records what you decide and shows you what you logged. No diagnoses, no dosing suggestions — structure for your own data.
Supplements next to peptides
Capsules, powders and sprays live in the same daily view, so one logbook covers everything you take instead of half of it.
Lab values with trends
Enter lab results and see them plotted over time. Peptly charts your numbers — it doesn't interpret or grade them.
WHOOP integration
Connect your WHOOP account to see sleep, recovery and strain alongside your own entries.
Reconstitution helper built in
Concentration and volume, calculated from the numbers you enter — vial size, solvent, your planned dose. It's arithmetic, not advice.
A public wiki with receipts
37 public entries, 129 cited sources, zero buy recommendations. Currently in German.
Accountability
Claims you can check
Everything below is verifiable — in the imprint, the privacy policy or the app itself.
Your data lives in the EU
Peptly's database runs in Stockholm, Sweden — not on a server “somewhere”.
A provider you can actually find
Operated from Germany under German consumer law, with a full legal imprint that names who is responsible.
No substance sales
Peptly sells software and nothing else. No shop, no shop links, no affiliate deals.
No third-party advertising
Your entries are not an ad product. There is no third-party advertising on this site or in the app.
Cancel anytime
Paid plans end via the statutory cancellation button German law requires — not a support-ticket maze.

FAQ
Three honest answers
Is my data stored in the EU?
Yes — Peptly's database is in Stockholm, Sweden. One exception, stated plainly: if you use the optional AI assistant, the excerpts of your data needed to answer your question are processed by a US-based AI provider, and only when you actively use it. Details are in the privacy policy (in German).
Can I use Peptly in English today?
Yes — the app interface is fully English (pick your language in Settings). The wiki content, legal documents and AI assistant answers are still German; translating those is a separate project we'll take on next.
Do you sell peptides?
No. Peptly is a documentation tool — a logbook for protocols you decide on yourself. There is no shop, there are no shop links, and the wiki describes substances without recommending anything, least of all where to buy them.
