RECONSTITUTION CALCULATOR — MATH-FREE Simply enter your vial size and desired dose. The calculator solves the optimal amount of BAC water and gives you the exact syringe draw. Supports mg, mcg, IU, and all standard insulin syringe formats. No more guessing your reconstitution math. DAILY DOSE TRACKER & INJECTION LOG Log every injection by time of day — waking, morning, evening, bedtime. Mark doses complete with one tap. See your full dosing history and protocol at a glance. Never miss a dose again. PROTOCOL MANAGEMENT & PEPTIDE STACK BUILDER Build custom protocols for any compound. Set frequency, duration, and dosing schedule. Track multiple peptides simultaneously and manage your full peptide stack without confusion. VIAL INVENTORY Know exactly how many doses remain in each vial. Track reconstitution dates, keep multiple vials per compound, and switch to a fresh vial without losing count. Never waste a vial again. WORKS WITH EVERY PEPTIDE & GLP-1 COMPOUND Whether you're managing a GLP-1 protocol, peptide cocktails like GLOW or KLOW, or a full biohacker peptide stack, compound-aware support is built in. BUILT FOR THE PEPTIDE COMMUNITY PeptideFox understands the real-life scenarios of compound reconstitution, injection tracking, and managing multiple vials and supply — the calculator, tracker, and inventory all work from the same data, so nothing needs entering twice. PRIVATE & SECURE All data stays on your device. No account required. No cloud. No trackigs to you. Terms of Use: https://www.apple.com/legal/internet-services/itunes/dev/

Serious tracking for peptides, GLP-1, TRT and HRT, with the bloodwork to see what actually changed. A precision instrument for people who run their own peptide, GLP-1, HRT and TRT protocols. Log a dose in a few taps or let scheduled protocols run on auto-pilot. See how much of each compound is in your system right now. Track a partner under the same roof, completely separately. Local-first and private. No efficacy claims, no gamification, no guilt. TRACK PROTOCOLS • The largest compound library in any tracker: peptides, GLP-1s, hormones and supplements • Dose logging in seconds, with titration schedules and cycle calendars • Injection-site rotation on a body map that counts every protocol you run, so a recently used site is marked before you pick it • Modeled Exposure: what's on board now, when your latest dose peaks, and where each blood draw fell on the curve • Adherence history and a verdict when a cycle ends CALCULATE • Eight calculators: dose and draw volume, BAC water, nasal spray, ester and pre-mixed oil, mix checker, half-life, steady state, daily burn • Transparent math. One tap turns a calculation into a protocol. KEEP INVENTORY • Vault: fridge, freezer and shelf zones, cap colors, and supply runway tied to your protocols • Photograph a kit's packing list to add vials in bulk; load a pen from a vial and keep the rest • Open what's known about a compound from the bottle itself TRACK YOUR HOUSEHOLD • Add a partner with their own protocols, logs, bloodwork and insights, kept separate, under one membership • One tap switches the whole app between people; a distinct color always shows whose data you're viewing • Reminders carry your partner's name; one shared Vault links vials to either person UNDERSTAND YOUR BLOODWORK • Import lab PDFs or photos; every value lands in a review queue where you confirm it before it counts • Trends across every report and every lab, units standardized, printed originals always preserved • Ranges shown are the ones printed on YOUR report. Optional Pro overlay: literature ranges, cited on screen, labeled educational • DEXA import: body fat, lean mass and more as baselines and trends • Doctor-Ready PDF: protocols, adherence, doses and labs in one document CONNECT YOUR BODY • Apple Health, Oura, WHOOP and Withings: sleep, HRV, resting heart rate and weight against your cycles • CGM glucose: time in range, and your glucose curve against your injections • A health score and biological age computed from your own labs LOG WHAT YOU EAT • AI food log: type or photograph a meal, review the estimate, correct it, approve. Nothing logs without your review. • One-tap repeat meals, recipes, unit conversion, and targets you set yourself PRIVATE BY DESIGN • Local-first: your data lives on your device, with optional encrypted cloud backup you control • Export as CSV anytime, free • No ads, no data sales, no social feed WHAT PEPTIDELAB IS NOT PeptideLab is a personal record-keeping and education tool. It is not a medical device and does not provide medical advice, diagnosis, or treatment. It never recommends, suggests, or adjusts doses, compounds, or protocols — every protocol in the app is one you enter yourself. Reference ranges displayed with your results are the ones printed on your own lab reports; optional educational ranges are cited to published literature and are clearly marked as non-diagnostic. Always consult a licensed clinician before you start, change, or stop any protocol or supplement. PeptideLab Pro (subscription) unlocks unlimited protocols, Modeled Exposure, the Lab Assistant, bloodwork trends and the Doctor-Ready PDF, Apple Health, Oura, WHOOP and Withings, CGM glucose reports, health score and DEXA body composition, household profiles, Food Log photos, protocol reports, and full history beyond 30 days. Core tracking, the calculators and CSV export are free, forever. Privacy Policy: https://peptidelabapp.com/privacy Terms of Use (EULA): https://peptidelabapp.com/terms

Verdict
The clearest difference is monetization model: PeptideFox at free against PeptideLab's freemium. PeptideLab's advantage is update cadence (daily vs weekly) and ratings volume (26 vs 3). On price, rating, review sentiment and ads there is nothing between them.
Scored on Price · Rating · Positive reviews · Number of ratings · Update frequency · Ads · In-app purchases · Monetization · Best chart rank · Devices · Requires iOS
Both are free to download. PeptideFox sells 2 in-app purchases, starting at $2.99 per month and PeptideLab sells 6 in-app purchases, starting at $4.99 per 7 days. Whichever you choose, the download price is not the number that matters.
PeptideFox holds the better App Store score, 5.0 against 4.8. That said, the two scores are not equally well evidenced: PeptideLab has 26 ratings behind it against 3, so its average is the more settled of the two. Written reviews point the same way: 100% of PeptideFox's written reviews are positive against 95% of PeptideLab's.
PeptideFox ships an update weekly, PeptideLab daily. The most recent releases landed on October 12, 2026 and October 20, 2026 respectively.
