Project Theo Membership — Protocol Tools, Research Library, and Compound Intelligence
Six ways in. Take the one that matches what you are stuck on.
Each plan below opens the full version of one Project Theo tool. You have probably already used the free layer of at least one of them. The plans are sold separately so you only pay for the question you are actually stuck on, and Full Access carries all three tools on one annual price.
Research Search Engine
Ask it anything about your stack, your compounds, or your protocol and get a direct research answer in seconds. It reads across the full body of Project Theo research, so you get a straight answer instead of a page of links to dig through. Unlimited questions with no resets, follow up threads that remember the whole conversation, saved history, and any answer exported as a full research document.
Get the Search Engine →Stack Calculator
Units to draw and water to add stay free for everyone. The membership puts several compounds on one shared timeline so you can see how a stack actually lines up. It shows where two compounds land on the same receptor, which is the docking site on a cell that a compound acts on, where they can quietly work against each other, and where the timing may need to shift. It answers how compounds fit together, not just what each one does on its own.
Get the Stack Calculator →Search + Calculator Bundle
Both tools on one subscription. The Research Search Engine for the question you are asking right now, the Stack Calculator for how the whole stack fits together. On their own they are $5.99 and $12.99 a month, so this is one plan instead of two.
Get the Bundle →Protocol Builder
The free builder gives you the general protocol. This is the detailed layer on top of the same result: a week by week titration schedule for each compound, meaning how the dose steps up over time, the reconstitution math worked out per compound, an overlap map for your stack, and a clear path to adjust when a protocol stalls. The subscription also opens the Protocol Check member layer, meaning the full correction plan and your result history on every check you run, and the full Guides Library.
Get the Builder →Guides Library
The full set of paid research guides in one place, the ones that go deeper than the free guides at the level of full stacks and complete protocols. That includes the Research Protocol Bible, Retatrutide: First Dose to Full Protocol, the Retatrutide, Tesamorelin and Ipamorelin stack, the Stack Compatibility Guide, MOTS-c and SS-31, MOTS-c: The Signaling Compound, and Intake and Output: The Full Self Assessment. One subscription opens every one of them, and the Protocol Builder and Full Access include the library too. Every guide opens as a guest preview on the library page, so you can read what each one covers before you decide.
Get the Guides Library →Full Access Membership
All three tools on one subscription, the Research Search Engine, the Stack Calculator and the Protocol Builder, plus the full Guides Library. This is the only annual plan here. The Protocol Builder on its own is $39.99 a month, which comes to $479.88 over the same year that Full Access costs $199.99. Everything above it is month to month and stops whenever you say so.
