PeptIQ is a sharp mobile-native dose tracker. MyProtocolStack adds blood work, calculators, and clinic plans. An honest comparison for serious peptide users.
Quick Take PeptIQ is a polished mobile-native peptide and injection tracker that launched January 2026. It logs doses beautifully, gamifies adherence with streaks, and ships native iOS and Android apps. If your protocol is straightforward and you only want a dose log on your phone, PeptIQ is a clean choice. MyProtocolStack covers more ground. We do dose logging too — but our reason for existing is the layer above it: connecting what you inject to what your bloodwork shows. We accept lab PDFs from Quest, LabCorp, Function Health, and most major US labs, parse them with AI, and analyze each marker in the context of the protocols you're running. We also serve clinics and practitioners, ship 16 calculators (vs PeptIQ's 5), and have published 122 educational articles on peptide and longevity protocols. If you want a phone app for dose tracking and nothing else, PeptIQ is the lighter pick. If you want bloodwork in the same dashboard as your protocol — or you're a practitioner managing multiple patients — MyProtocolStack is the more complete answer. Pricing tilts the same way: MyProtocolStack Optimizer is $14.99/month versus PeptIQ Premium at $19.99/month, and MyProtocolStack's free tier includes lab tracking, which PeptIQ's free tier does not offer.
Honesty first. PeptIQ ships a few things genuinely well, and we recommend them where the fit is right.
Native mobile presence. PeptIQ has real iOS App Store and Google Play listings. MyProtocolStack is a Progressive Web App — fast and installable, but not browseable in App Store search. For users who discover apps by browsing categories on their phone, PeptIQ has an organic acquisition channel we don't yet match.
Streak and adherence gamification. PeptIQ's UI rewards consistency with badges, milestones, and streak counters. The behavioral science on streak-based gamification in health apps is solid — small dopamine hits from a 7-day or 30-day streak can meaningfully improve protocol adherence. MyProtocolStack tracks adherence (we surface a 30-day adherence percentage) but we don't gamify it. If gamification keeps you logging, that's a real reason to prefer PeptIQ.
Clean consumer UX for simple protocols. The PeptIQ dashboard is uncluttered, the dose log is fast, and the cycle scheduler handles common patterns (continuous, on-off, ramp-up) well. For a user running one or two peptides on a simple cycle, PeptIQ is genuinely pleasant to use.
Claim Auditor. PeptIQ ships a feature where you can paste an influencer's claim about a peptide and get an AI-generated verdict with credibility score and references. It's a smart, share-friendly tool. MyProtocolStack doesn't have this yet — it's on our 2026 roadmap.
3-day free Premium trial. PeptIQ offers a 3-day free trial of Premium with no credit card required up front. Lower friction for fence-sitters who want to try the paid features before committing.
We say this all sincerely. PeptIQ's founder Kris Chase has built a focused, well-designed product, and the iOS rating reflects that. Our comparison is not "PeptIQ is bad" — it's "PeptIQ and MyProtocolStack solve overlapping but distinct problems."
Same honesty.
No blood work layer. This is the biggest structural gap. PeptIQ has no lab PDF upload, no biomarker tracking, no reference range visualization, no AI lab analysis. Their AI Coach reads your protocol context and your dose history, but if you want to know what your IGF-1 actually did over your last GH peptide cycle, you can't. MyProtocolStack was built around this gap — extracting a Quest or LabCorp PDF, normalizing 150+ biomarkers, and reading your panel in the context of what you're running is our core wedge.
Five calculators vs sixteen. PeptIQ ships Reconstitution, Dosing, Unit Converter, Vial Duration, and Cost Calculator. MyProtocolStack ships those plus Reverse Calculator, Half-Life Decay, GLP-1 Titration Schedule, BAC Water Calculator, Insulin Syringe Unit Converter, IGF-1 Optimal Range Calculator, Body Fat % from circumferences, TDEE estimator, Protein Target by lean mass, and protocol-stack interaction screener — 16 total. For users who want their tracker to also handle the math around their protocol, this is a meaningful gap.
Mobile-only. No web app for serious data work. PeptIQ has a web preview at app.peptiq.io, but the product is designed for the phone. MyProtocolStack is a real web application that also works on phones — and there's a reason: serious longevity work involves spreadsheets, lab PDFs, and screen real estate that a phone can't comfortably surface. If you've ever tried to compare three lab panels side by side on a 6-inch screen, you understand the problem. MyProtocolStack handles both modalities.
No B2B surface. PeptIQ has no clinic plan, no practitioner plan, no multi-patient view, no white-label option, no HIPAA-adjacent infrastructure for clinical contexts. MyProtocolStack has all of these — Clinic and Practitioner tiers exist, and 14 partner clinics are currently using the platform. If you're a clinician evaluating tools for your practice, PeptIQ doesn't compete in this category.
Limited free tier. PeptIQ's free tier caps at 3 active peptides, 2 active protocols, and 7 days of injection history. After 7 days your dose log starts disappearing unless you pay. MyProtocolStack's free Explorer tier is unlimited for the core tracking and lab tools — no cap on lab draws, no cap on dose logs, full biomarker dashboard. We monetize the AI analysis layer; we don't lock the basic tracking.
Smaller content library. PeptIQ's blog has approximately 15-25 posts. MyProtocolStack has 122 educational articles spanning peptides, GLP-1s, hormones, biomarkers, and clinic-side topics. Content depth matters when you're learning a new protocol — there's a reasonable chance the question you have is already answered on our blog with citations and bloodwork context.

|---|---|---|
MyProtocolStack is 25% cheaper at every billing interval. The annual plan saves you about $10/year over PeptIQ's annual plan, and our free tier removes the time-pressure of PeptIQ's 7-day history limit.
It's reasonable to use PeptIQ for the on-phone dose logging if you've built that habit, and use MyProtocolStack for the lab work, calculator suite, and weekly bloodwork-aware coaching. The data layers don't currently sync between the two products, but for users who value the gamification of one and the depth of the other, running both is a workable pattern.
PeptIQ is a focused consumer dose tracker built well by a solo founder. MyProtocolStack is a broader platform built around the bloodwork layer that PeptIQ doesn't have. The choice depends on what you're tracking.
If your protocol question is "did I inject today" — PeptIQ.
If your protocol question is "what did my IGF-1 actually do over the last 8 weeks of my GH stack, and how does my SHBG explain the free testosterone drop, and is my hs-CRP trending in the right direction now that I added GHK-Cu" — MyProtocolStack. PeptIQ's coach can't read those numbers because PeptIQ doesn't store them.
For users serious enough about their protocols to be reading a comparison post in the first place, the bloodwork layer is usually the right tiebreaker. We built MyProtocolStack because we believed the dose-only trackers were leaving the most important question — "is this protocol actually working" — unanswered.
You can try the MyProtocolStack free Explorer tier (unlimited lab uploads, dose logging, biomarker dashboard) at [myprotocolstack.com](https://myprotocolstack.com), or take a 14-day free trial of Optimizer ($14.99/month after) to test the AI bloodwork analysis on your own panels.
