PepCue vs Shotlee.
Shotlee is one of the broadest trackers in this category. It covers GLP-1 medications, research peptides and hormone therapy in one app, runs on iPhone, Android and a web dashboard, and pairs the tracker with an AI companion, Apple Health integration, a community chat and a very large library of articles and calculators. PepCue is narrower and grows more slowly on purpose. Its bet is that a smaller library where every compound carries a computed, published grade is worth more to some readers than a larger one where it does not.

You want each compound graded on a disclosed model before you read anything else about it, you want tracking that is free with no account, and you would rather your log stayed on your phone.
You want one app for a GLP-1, a peptide and hormone therapy together, on Android or in a browser as well as on iPhone, with an AI companion that writes weekly summaries and a community of people on the same medications. Shotlee has all of those. PepCue shares the multi-compound tracking, an in-app assistant and Apple Health on iPhone, but has no web version of your log.
Checked against Shotlee's App Store listing and its own website in October 2026, and their column comes from those two sources. We have not printed a price, a rating or a review count, and we have not audited the accuracy of Shotlee's articles, so this page makes no claim about them either way.
Side by side, verifiable rows only.
| PepCue | Shotlee | |
|---|---|---|
| Price | Free to use. You can run a full protocol without paying, and there is no subscription gate on logging, schedules, the calculators or the evidence library. | Free to download, with an optional Shotlee Pro subscription sold in the app. Amounts are left off on purpose; check their listing. |
| Platforms | iPhone and Android apps, plus this website, where the calculators and the evidence library run with no install. | iPhone and Android apps, plus a web dashboard. |
| Scope | Peptides, GLP-1 medications and TRT on one timeline, with 69 compounds profiled on the website. | GLP-1 medications, research peptides and hormone therapy, including TRT, HRT and HCG. |
| AI assistant | PepCue AI, an in-app assistant, answers questions about what you have logged. A safety filter turns away dosing, sourcing, diagnosis and medical-advice questions before they reach the model. | Yes, an AI companion that generates personalised insights and weekly summaries. |
| Health app sync | Apple Health on iPhone: with your permission PepCue reads weight, body composition, heart rate, sleep and active energy, and can save logged weight back. Google Health Connect sync is not advertised. | Apple Health integration for importing and exporting data. |
| Community | No community feed and no certificate-of-analysis sharing. | Yes, a community chat with private messaging. |
| Evidence grading | Every compound carries an S to F evidence tier scored on six axes: human evidence, preclinical depth, mechanism confidence, safety clarity, regulatory clarity and practical relevance. | Says its articles are built from primary sources such as FDA labels, prescribing information and peer-reviewed trials. Whether compounds carry a graded evidence score, we have not verified. |
| Scoring model published | Yes. The full six-axis model, the tier thresholds and a worked example on a real compound are published on the methodology page. | Not verified |
| Citations | 306 cited sources across 69 compound profiles, plus a generated research index of 274 unique PubMed records, every one pulled from NCBI and re-resolved against live PubMed by an audit script kept in the repo. | Not verified |
| Calculators | 9, free in the browser with no account and no install: reconstitution, blends, GLP-1 titration, pen clicks, vial longevity, unit conversions and BAC water. | Its site hosts reconstitution, syringe, pen-click and other calculators. Whether any of them need an account, we have not verified. |
| Provider export | A summary document of protocols, logged doses, sites, symptoms and weight history for a date range you choose. It reports what you logged and interprets nothing. | PDF export for sharing with a doctor. |
| Affiliate codes or vendor rankings | None. PepCue sells no peptides, ranks no vendors, takes no kickbacks and places no affiliate codes. | Not verified |
| Dosing guidance | Never. PepCue explains compounds and does the arithmetic on numbers you enter. It does not tell anyone what to take. | Not verified |
| Where your data lives | Protocols, doses, inventory, weights and check-ins are stored on your device rather than on our servers. | Its App Store privacy label lists health and fitness data among the data linked to you, and its site says data is stored securely and never sold to advertisers. |
What PepCue does differently.
The honest framing is breadth against depth. Shotlee covers more medications, more platforms and many more pages than PepCue does, and its site says those pages are researched from primary sources: FDA labels, prescribing information and peer-reviewed trials. PepCue does not dispute that. Its claim is narrower. On PepCue, every compound carries a grade that is computed rather than written, and the rules for computing it are public.
That grade runs from S to F and comes from six scored axes: controlled human evidence, preclinical depth, mechanism confidence, safety clarity, regulatory clarity and practical relevance. The thresholds and a worked example on a real compound are on the methodology page. The point is not that a letter is more accurate than an article. It is that a reader who disagrees can name the axis they think is wrong, and a compound with deep animal data and no human trials cannot hide that gap behind a well-written page.
The sourcing is checked by machine rather than by trust. Across 69 profiles there are 306 cited sources, and a generated research index of 274 unique PubMed records is pulled from NCBI and re-resolved against live PubMed by an audit script kept in the repo. A smaller library is easier to hold to that standard, which is part of why PepCue grows slowly.
The rest is practical. PepCue is free to use with no account, and the 9 calculators run in a browser with no install. Tracking data sits in a database on your phone rather than on a server. There are no affiliate codes, no vendor rankings and nothing for sale anywhere on the site, and no page tells anyone what to take.
Where Shotlee is stronger.
Shotlee does more than PepCue in several directions at once, and each is a real reason to choose it. The AI is the first. Both apps have an assistant, but Shotlee's writes weekly summaries and personalised insights for you, while PepCue AI answers questions about your log and turns away anything that reads as dosing advice. If you want the summaries written for you, PepCue does not do that.
Platform reach is the second. Both apps run on iPhone and Android, but Shotlee adds a web dashboard, so the same log can be reviewed on a laptop. PepCue keeps the log on your phone, which is better for privacy and worse if you want your history on a bigger screen.
The community chat is the third. A community of people on the same medications offers something no reference site can: other people's lived experience. On Apple Health the two are closer than they look, since both connect to it on iPhone.
Scope is the last. Shotlee's coverage runs past TRT into HRT, HCG and other injectables, and the app is offered in many languages. If your protocol leans on hormone therapy, or English is not your first language, that breadth may matter more to you than a grading model does.
FAQ.
Is Shotlee or PepCue better for GLP-1 tracking?
Both track GLP-1 medications alongside other compounds. Shotlee adds an AI companion, Apple Health integration, a community and a web dashboard. PepCue adds a graded evidence profile for each compound, built on a published model, and keeps the log on your phone. If GLP-1 tracking is the whole job, the extra features may matter more to you than the grade.
Is Shotlee free?
Shotlee is free to download and sells an optional Pro subscription in the app. We do not print its price because pricing changes and we would rather you saw it at the source. PepCue is free to use, and a full protocol can be run without paying.
Does Shotlee publish more articles than PepCue?
Yes, by a wide margin, and it says they are researched from primary sources. PepCue publishes fewer pages and attaches a computed S to F grade, a published scoring model and NCBI-audited citations to each compound. More pages and graded pages are different goals, and both have readers.
Does PepCue have an AI companion or Apple Health sync like Shotlee?
Both, in a narrower form. PepCue AI answers questions about what you have logged and turns away dosing, sourcing and diagnosis questions. On iPhone, PepCue reads weight, body composition, heart rate and sleep from Apple Health and can save weight back. Google Health Connect sync is not advertised.
