The Protocol Engine — $19
Stop guessing when to take your stack. Tell the Protocol Engine your supplements, your fasting window and your training, and it builds your exact daily timing schedule — personalised to you, in under a minute.
What you get:
- Stack Audit — flags absorption clashes, upper-limit overlaps and synergies across your stack, each with the mechanism, the fix and the source.
- Cited evidence layer — 67 ingredients and branded products with sourced dosage ranges, labelled so you can see which are backed by a published intake level and which reflect common practice.
- The Protocol Engine — your personalised daily timing schedule, built around your stack and your wake, eat, train and sleep windows. Yours to keep and re-run whenever your stack changes.
- 14-Day Tracker — run your new protocol and see what is actually working.
- Training-aware timing — enter your session and the Engine builds pre- and post-training blocks, flags fasted sessions and late caffeine, and sets out the evidence on protein timing.
One-time payment. Prices shown in USD; international buyers are charged in their local currency at checkout. Payments are processed securely by Gumroad, our Merchant of Record, which handles all applicable taxes.
