MyProtocolStack
Protocol + biomarker tracking software for serious peptide and longevity users.
The software platform that finally gave peptide and longevity protocols proper instrumentation.
Most people running serious peptide protocols are tracking them in Notion docs, Google Sheets, or worse. MyProtocolStack is the purpose-built alternative: dose logs, cycle tracking, biomarker history, lab uploads, side-effect tracking, AI-driven protocol coaching.
The product covers the workflows that matter for the longevity-curious operator: stacking multiple peptides with overlapping cycle plans, correlating biomarker movement with protocol changes, sharing read-only dashboards with a clinician or coach, and StackAI — a longevity-tuned chat that knows your protocol history and lab data.
Disclosure: MyProtocolStack is the publisher of Lifespan Vault. We feature it because it's genuinely the only purpose-built tracker for this audience — not because of the relationship. Free tier is meaningful (single protocol + basic tracking); Optimizer ($39/mo) unlocks unlimited stacks, lab uploads, and StackAI.
Anyone running 2+ peptide protocols, tracking biomarkers across cycles, or wanting protocol-aware AI coaching.
You only run a single simple protocol and prefer paper logs, or you don't track biomarkers.
