Everything PepStack does - and why each piece matters for running a serious peptide protocol.
Track every peptide cycle from start to finish. Set planned durations, log washout periods, and keep a complete history of every compound you have run.
Log every injection with compound, dose, administration site, and timestamp. Frequency patterns are derived automatically from your log - no manual schedule setup required.
Track vials by peptide, concentration, and volume remaining. Doses drawn are calculated automatically and low-stock vials are flagged before they run out.
Run multiple peptides simultaneously in a single stack. Each compound is tracked independently with its own dosing schedule and vial inventory.
Log results from any standard panel - CBC, metabolic, lipids, hormones, and custom markers. Values are stored against the draw date for trend tracking across cycles.
Submit your lab results for AI analysis correlated to your active stack. Identifies out-of-range markers and flags potential compound interactions.
See how key markers move across multiple draws alongside your protocol history. Track CBC, lipids, hormones, and liver markers over time.
A research assistant for compound-specific queries. Ask about dosing, interactions, or bloodwork - answers include inline PubMed references you can verify yourself. Pro plan.
AI evaluation of your current stack: compound synergies, potential concerns, and goal alignment based on your actual protocol data and bloodwork.
Describe a goal and get a protocol recommendation with compound selection, dosing rationale, and cycle structure tailored to your profile.
Every AI response that references research links directly to the source PubMed paper. You always see where the information comes from.
Curated templates spanning recovery, performance, cognitive, metabolic, and longevity goals. Each includes compound selection rationale and dosing guidance.
Dosing ranges, half-life, administration route, evidence tier, and research notes for every supported peptide - BPC-157, TB-500, CJC-1295, Ipamorelin, GHK-Cu, and more.
Each compound is rated from Tier 1 (clinical evidence) to Tier 5 (observational only) so you always know how strong the evidence base is before making protocol decisions.
Stack data, injection logs, and bloodwork markers are stored in a private database tied to your account only. No data is shared with third parties or used for advertising.
Sign in on any device and your full protocol history, vial inventory, and bloodwork records are available immediately. No manual export or import required.
Bloodwork documents are processed locally in your browser. The raw image is never sent to or stored on the server - only the extracted marker values are synced.
Free plan available. Pro unlocks AskPep, advanced bloodwork analysis, and unlimited AI queries.
