A peptide tracker that charts Apple Health, Oura and WHOOP data next to your log, with AI that answers questions about your own history, a community and web research tools.

Quick verdict

Peptide Library or PeptIQ?

PeptIQ connects your log to Apple Health, Oura and WHOOP, adds AI that answers questions about your own history, and offers web research tools such as an FDA status checker and an interaction checker. It's on iPhone, Android and the web. Peptide Library matches that reach and adds what PeptIQ says it doesn't do: vendor listings and price comparison, alongside cited research profiles, publication data and a free plan that includes tracking.

The difference

What makes Peptide Library different?

  • Wearables and health data

    PeptIQ brings in sleep, HRV, resting heart rate, steps and weight from Apple Health, plus Oura and WHOOP. Peptide Library reads weight and body fat from Apple Health or Health Connect.

  • Vendors: stated no, or a Shop

    PeptIQ's listing says it does not sell or source peptides or list vendors; its site has a cost-per-mg calculator for offers you enter. Peptide Library compares vendor listings with price per mg and reviews.

  • Two kinds of research tools

    PeptIQ shows sources on compound pages and AI answers and offers checkers on the web. Peptide Library's profiles cite their sources, and its Research Intelligence Center publishes publication and trial statistics.

  • Price

    PeptIQ Premium is listed weekly, monthly and yearly, from $9.99 a week to $129.99 a year. Peptide Library Pro is $4.99 a month, $39.99 a year or $89.99 once.

These pieces work together: read a profile, compare vendors on price per mg, add what you bought to inventory, and every logged dose updates your stock, calendar and journal.

Research

Research library: a reference platform or a tracking companion?

PeptIQ has an educational library and glossary, and its latest release shows sources (PubMed, FDA, ClinicalTrials.gov) on every compound page, AI answer and protocol step. Its website adds tools such as a claim auditor, research by goal, an FDA status tracker and an interaction checker.

Peptide Library's 200+ research profiles cite PubMed, ClinicalTrials.gov, DailyMed and EMA sources and label evidence by type. The Research Intelligence Center adds publication and clinical-trial statistics with a published methodology, and Peptide Trends shows what the community researches.

Browse the 200+ research profiles · See the Research Intelligence Center

Tracking

Tracking, scheduling and inventory workflows

PeptIQ's Today screen shows what's next with one tap to log or skip, and entries record amount, time, route and site as done, skipped or missed. Protocols run daily, weekly, cycling or custom, with pause and resume and a calendar view.

Peptide Library covers the same core loop and adds titration, several times a day and schedules per product form. For stock, PeptIQ tracks vials and pens with low-stock and expiry alerts; Peptide Library also deducts stock as you log and forecasts run-out and reorder-by dates.

Vendors

Vendor and pricing research

PeptIQ is explicit that it is not a marketplace and does not list vendors, though its website offers a calculator to compare cost per mg for offers you enter yourself. Peptide Library's Shop lists vendor offers by compound and product form, with price per mg after any coupon code and vendor profiles with reviews.

  • Compare listings

    Offers grouped by compound and product form, never mixed across forms.

  • Price per mg

    Unit prices after any vendor coupon code, from what the listing shows.

  • Vendor profiles

    Reviews, coupons and the shipping details a source supports.

About vendor listings. Vendor listings, prices, reviews, coupon codes and commercial partnerships are not independent proof of a product's purity, safety, legitimacy or suitability for human use, and a listing is not an endorsement. Peptide Library does not sell peptides. Some vendor links are affiliate links; affiliate status never changes the order vendors appear in.

Final verdict

The verdict on Peptide Library vs PeptIQ

PeptIQ is the stronger pick for people who want wearable and health data next to their log, and AI on top of it. Peptide Library is the stronger pick for research depth and vendor comparison, and costs less at list price.

Both cite sources and both run everywhere, so the choice comes down to whether you value wearables and AI or vendor and research data more.
