Where are you starting?
Start with a safe, plain-English walkthrough — what to take, how to source it, and your first protocol, step by step.
Start HereDial in exact doses, verify your vials, compare compounds, and track results against your bloodwork.
Explore the toolsCycle-synced timing, female-specific dosing, and fertility safety — built around your body, not a male template.
Open the women's hubThe real problem
You're spending real money on compounds — and trusting forums, screenshots, and strangers with the rest.
PepCompass replaces all of that guesswork with one calm, evidence-graded system.
How it works
Answer a few questions and get a peptide, dose, cycle length, and supply list matched to your goal — in plain English.
Score your Certificate of Analysis, calculate the exact units to draw, and follow photo-by-photo reconstitution and injection guides.
Log how you feel, watch the trends, run protocol-specific bloodwork, and let the engine flag what's actually changing.
What you get
The trust content is free. The daily-driver tools are a few dollars a month — pennies next to what you spend on the peptides themselves.
Paste your COA numbers and get an instant A–F confidence grade — purity, identity, endotoxins, lab accreditation — so you never inject a fake.
Enter vial size, water, and target dose — get the precise insulin-syringe units to draw, shown on a real syringe.
14 markers, side-effect tracking, and a signal engine that surfaces lines like 'recovery up 18% after your dose change.'
A lab panel built for your exact protocol, retest reminders, and plain-language interpretation of every result.
Check any combination of peptides, meds, and conditions for interactions before you run it — not after.
Phase-timed protocols, GLP-1 titration synced to your cycle, and a fertility safety checker no other app has.
No account needed — try the injection-site map, dose calculator, and COA checker free.
Every peptide rated Supported → Hypothesis with the human, animal, and safety data behind it.
We don't sell peptides and take no supplier commissions. Our only incentive is your trust.
From BPC-157 to the GLP-1s — dosing, timing, side effects, and references, all clearly explained.
Almost every peptide protocol was dosed and timed for men. We sync your protocol to your cycle, time GLP-1 increases to when nausea tolerance is highest, and check every compound against fertility and pregnancy — the things no other platform does.
