    Decay curves and Apple Health on the same axis.

  • PinPal Daily Insights reading the week's biomarkers against the published literature — a resting-heart-rate rise interpreted as on-profile for retatrutide, citing Eli Lilly's Phase 2 trial.

    Reads your week. Cites the trial.

  • PinPal Tirzepatide detail page showing the FDA Approved Phase 3 RCT evidence badge and Conservative / Standard / Aggressive dose ranges, each sourced to Eli Lilly's SURMOUNT-1 trial.

    Evidence tier and dose ranges, all sourced.

Everything between your doses.

  • Pharmacokinetic decay curves

    See the active level of every compound between doses — not just the day you injected.

  • Apple Health on the same axis

    Resting heart rate, HRV, sleep, glucose and weight overlaid directly on the decay curve.

  • Cited daily insights

    Your week, read against the literature — every claim sourced to a published trial.

  • A library that cites its work

    31 peptides, each with an evidence tier and the trial it rests on.

  • Chat that knows your stack

    Ask anything about your protocol; answers stay grounded in the peptide literature.

  • Reconstitution math

    Convert a vial's mg strength into syringe units in seconds. Units, not dosage advice.

  • Decay curves for every protocol you run, with your Apple Health biomarkers (HRV, RHR, weight, sleep) overlaid on the same axis. Tap a dose; see what changed.

  • No. It's a tracking and information tool. Doesn't diagnose, treat, or prescribe.

  • 31 curated peptides covering GLP-1s, healing, growth, and cosmetics, with cited dose ranges and half-lives. Custom protocols like TRT, HCG, and HGH work too.

  • Yes. Paste your protocol history straight from Apple Notes, a Google Doc, or any other tracker. PinPal extracts the doses, dates, weight checks, and BP readings, and turns them into a live timeline. Free accounts import one protocol. Pro replays the rest from staging the moment you upgrade.

  • Yes. Log your cycle alongside doses and biomarkers and see them on the same chart. Useful for anyone running GLP-1s, BHRT, or aesthetic peptides who wants to spot timing patterns.

  • Yes. Food and macros from Cal AI and MyFitnessPal land on the same axis as your decay curve, alongside HRV, weight, and sleep from Apple Health.

  • It stays on your device. PinPal reads HRV, RHR, weight, and sleep locally to overlay on your decay curves. Biomarker values are never sent to our servers.
