For a researcher running two or more compounds who is not getting the result the data says to expect, and who has never seen the half-lives and receptors on one timeline. The Subscribe button is above this page. $12.99 a month. Cancel anytime. The units and water calculator stays free for everyone. Example stack read Retatrutide, about a 6 day half-life Tesamorelin, half-life under an hour Ipamorelin, about a 2 hour half-life GLP-1 receptor: retatrutide active across the whole week. GHRH receptor: tesamorelin active only around the injection. No shared receptor between the growth hormone peptides and retatrutide. Timing note: GLP-1 activity slows how fast the stomach empties, so a meal can take longer to clear, and an ipamorelin injection timed on the usual fasted clock may not land in a fasted state. Example only. Your stack, your curves, and your flags are generated from the compounds you enter. The calculator and a single compound read are free. Adding a second compound opens the receptor overlap curves, the conflict map, injection day optimization, and the 7 day schedule. Subscribe above to unlock it. You already have access Your subscription covers the Stack Calculator. Open it and run the full stack. Open the Stack Calculator The problem it solves Running two compounds at once is not the same as understanding how they run together. A half-life, meaning how long a compound stays active, decides when a receptor is occupied and when it is free, and two compounds can work at cross purposes without the researcher knowing it. The Stack Calculator puts every compound on one shared timeline, flags where two land on the same receptor at the same time, where the timing creates a problem, and which injection day lowers the peak. It is the check that runs before the stack does, not after something stops working. What membership adds The free tool is the proof. The paid layer is the reason. Free Units to draw, water to add, doses per vial, and blends, with no email asked Single compound analysis with its half-life curve Titration ladder and frequency impact for that compound Save this research Two or more compounds at once Receptor overlap curves Conflict map Injection day optimization 7 day schedule and calendar export Member Everything in the free tool Up to 8 compounds on one timeline Receptor overlap curves across the full stack Conflict map with receptor, timing, and pairing flags Injection day optimization with the best available offset 7 day schedule with calendar export The full stack read saved to Your Research, where it prints Printing and PDF live on Your Research, not inside the tool. How it works 1 Enter the compounds you run Pick each one from the reference set with its dose and frequency. One compound is free. Two or more is the member layer. 2 Read the timeline Each compound is plotted across a 7 day window. Shared receptors, timing conflicts, and pairing flags show up in one place with the reason behind each one. 3 Move the injection day and watch the numbers The day offset view shows how the combined load at a shared receptor changes across every schedule, so the choice is made before the week starts. Export the schedule to a calendar. Pricing Standalone, bundled with the Search Engine, or the full year. Six products, sold separately, so you only pay for the part you are stuck on. Every row below opens that product. Research Search Engine$5.99 / month Ask anything about a protocol and get a research grounded answer in seconds. Unlimited questions, threaded follow up, saved history, and answer export. Stack Calculator$12.99 / month Units to draw and water to add, free for everyone. Members put up to 8 compounds on one timeline and see where half-lives overlap and where the timing needs to move. This page. Subscribe above Search + Calculator Bundle$15.99 / month Both tools on one subscription. On their own they are $5.99 and $12.99 a month, so the bundle is $2.99 a month less. Protocol Builder$39.99 / month The full layered protocol with a week by week titration calendar, the reconstitution math, the receptor map, and the if it stalls path. Includes the Protocol Check member layer and the full Guides Library. Guides Library$19.99 / month Seven research guides on protocol design, sequencing, stacking, and dose logic. Included with the Protocol Builder and with Full Access. Full Access Membership$199.99 / year All three tools plus the full Guides Library on one subscription. Bought separately for a year the four come to $947.52. The only annual plan. The math, run plainly. A year of the Stack Calculator at $12.99 is $155.88. Full Access is $199.99 for the year, $44.11 more, and it adds the Research Search Engine, the Protocol Builder ($479.88 a year on its own) and the full Guides Library. The Bundle at $15.99 adds the Search Engine for $3.00 more a month than this page, which is $2.99 less than buying both. Questions What is free in the peptide stack calculator?The reconstitution calculator is free with no email: vial size, water, syringe type, units to draw, doses per vial, and blends where several peptides come out of one vial. A single compound read, with its half-life curve and titration ladder, is free with an email. Saving a result is free for everyone.What does the $12.99 subscription add?The stack itself. Two to eight compounds on one timeline, receptor overlap curves for every pair that shares a receptor, the conflict map with receptor, timing, and pairing flags, injection day optimization, and the 7 day schedule with a calendar export. The full stack read saves to Your Research and prints from there.Which email unlocks it?The email you use at checkout. Enter the same address in the tool and the gate reads the subscription. If another Project Theo tool in this browser already holds your email, the calculator offers it first.Can I cancel?Yes, anytime, from the Manage Subscription page. Month to month. Full Access is the only annual plan.Does this include the Guides Library?No. The Guides Library is $19.99 a month on its own and is included with the Protocol Builder and with Full Access. The Stack Compatibility Guide in the library covers the same decision this tool runs the numbers on.My stack looks fine on the timeline and results still stalled. What next?A clean timing picture does not rule out the blood. The free Bloodwork Diagnostic Tool turns goals and symptoms into a panel to take to a doctor, and the free Protocol Check, about 5 minutes, names the most likely bottleneck before anything changes. Your Research keeps everything you save from every tool in one place and opens all of it. Any active subscription opens every saved entry, so a result you ran before you subscribed is waiting when you come back. For educational and research purposes only. Not medical advice.
