PeptidePal is the most heavily marketed peptide tracker in the niche, and on iPhone it is genuinely capable. This is an independent look at what it does well, where the documented complaints are, what it really costs, and the naming confusion you should know about before you install it. We take no affiliate money from PeptidePal or anyone else.

The verdict
For an all-in-one GLP-1, peptide and TRT log on iPhone, PeptidePal delivers: dose logging, vial inventory, a reconstitution calculator, reminders and an AI advisor in one polished app. The catches are worth knowing. Its marketing ("Free", "5.0 on the App Store") reads rosier than the actual App Store listing, which shows a 4.7 average from about 4,200 ratings and paid tiers from $8.99 per month. Several unrelated apps share the name. And its headline vial inventory has drawn credible "it doesn't deduct my doses" complaints. Confirm the developer is Blank Labs LLC, and try the free tier before you pay.

What PeptidePal costs
PeptidePal is free to download with in-app purchases. As listed on the App Store in August 2026, the Pro subscription is shown in a range - roughly $8.99 to $19.99 per month, or $29.99 to $59.99 per year - depending on the plan surfaced at checkout. The free tier is limited; Pro unlocks unlimited stacks and the fuller feature set.
One thing to flag plainly: the marketing site leads with "Free", which is true of the download but not of the features most people actually want. The paid line is real, and it is in the store listing, not on the landing page.
What it does well
Credit where it is due - PeptidePal is the most complete and polished tracker marketed in this space, and several of its features are exactly what a serious protocol needs:
One app for GLP-1 shots (Ozempic, Wegovy, Mounjaro, Zepbound), research peptides (BPC-157, TB-500, CJC-1295 and more) and TRT.
Dose logging with one-tap entry and injection-site rotation.
A vial inventory with expiration tracking and low-stock alerts.
Built-in reconstitution, dose and dilution calculators.
Scheduling and customizable reminders.
An AI advisor described as stack-aware, with on-device storage and optional iCloud sync, and offline use.
The documented complaints
A fair review names the weak spots too. These are drawn from PeptidePal's own store reviews and listing, not from hearsay.
The vial inventory may not auto-deduct logged doses
The inventory feature is a headline selling point, so this is the complaint that stings. A verbatim App Store review:
"When I log a dose, it doesn't deduct it from my vial of medication. It just has a chart that estimates when I'll run out ... I could just write it down on a post it note too. If I'd known it didn't function as promoted, I'd never have purchased it."
In fairness, the developer replied that logged doses should deduct automatically when the vial is configured correctly, and offered to troubleshoot by email. So this may be a setup or edge-case issue rather than a missing feature - but it is a recurring theme, and it is worth testing on the free tier before you rely on it.
The advertised rating is higher than the store average
The marketing site claims "5.0 on the App Store". The App Store listing itself shows a 4.7 average from about 4,200 ratings as of August 2026. A 4.7 is a good score; the gap between it and the advertised "5.0" is the point. Our read (opinion, not fact): treat the on-page testimonials as marketing and weight the store's own written reviews, positive and negative, more heavily.
Platform claims are inconsistent
The App Store description calls it "the only iOS app" combining GLP-1, peptides and TRT, while the marketing site advertises Android and links a Google Play page. That may reflect a new Android build in progress, but if you are on Android, confirm the current listing and feature set before assuming it matches the iPhone version.
Read this before you install
More than one app is called PeptidePal
The name is crowded, and it is easy to install or pay for the wrong app. As of August 2026:
The app reviewed here is by Blank Labs LLC (App Store; Google Play id com.blanklabs.peptidepal). This is the heavily marketed one with about 4,200 ratings.
A different App Store app also named PeptidePal is published by Signalworks Labs Inc. - a separate product with far fewer ratings and different pricing.
A separate PeptidePal on Google Play comes from an independent developer (Jivesh Bhatti) and is unrelated to the above.
Before you install or subscribe, check the developer name on the listing. If it does not say Blank Labs LLC, it is a different app than the one in this review.
Who it fits
iPhone users running GLP-1s, peptides and TRT who want one polished app for all of it and do not mind a subscription.
People who value a built-in AI advisor and a single-app workflow over free and open tools.
It is a weaker fit if you are on Android and need parity, if you want a real free tier, or if you specifically need vial inventory that you can trust to deduct without fiddling with setup.
Alternatives worth a look
None of these pay us, and we include our own project openly:
PeptIQ - Full free tier across iOS, Android and web.
Shotlee - Free GLP-1 and peptide tracker on iOS and Android.
Regimen - Native apps plus free no-login web calculators.
PepTracker - iPhone dose log with a built-in reconstitution calculator.
Pepteca - our cited compound library and free calculators now; a tracker is in development.
Questions people ask
Is PeptidePal legit?
Yes, it is a real, actively updated app from Blank Labs LLC, with a 4.7 star average from about 4,200 App Store ratings as of August 2026. The things to know are that its marketing ('Free', '5.0 on the App Store') reads rosier than the App Store listing (a 4.7 average and paid tiers from $8.99 per month), and that several unrelated apps share the PeptidePal name, so confirm the developer is Blank Labs LLC before you install or pay.
How much does PeptidePal cost?
The app is free to download with in-app purchases. As listed on the App Store in August 2026, the Pro subscription runs about $8.99 to $19.99 per month or $29.99 to $59.99 per year, depending on the plan shown at checkout. The free tier is limited; the paid tier unlocks unlimited stacks and the fuller feature set.
Does PeptidePal work on Android?
It is primarily an iPhone app - the App Store listing itself describes it as 'the only iOS app' combining GLP-1, peptides and TRT. The marketing site advertises Android and links a Google Play page, so an Android build may exist or be rolling out, but iOS is where the reviewed, established version lives. Check the current store listings before assuming feature parity.
What are the best PeptidePal alternatives?
If you want a genuinely free tier, look at PeptIQ or Shotlee. Regimen pairs native apps with free web calculators. Pepteca (our own project) offers a cited compound library and free calculators now, with a tracker on the way. See our roundup of the best peptide tracker apps for the full comparison.
Pepteca is for education and information only. It does not provide medical advice, diagnosis, or treatment, and its calculators perform unit math only. Always verify with a licensed provider before starting, changing, or stopping any protocol. Many peptides are not approved for human use and may be regulated differently where you live.
