Project Theo is a research resource for people running peptide protocols or thinking about starting one and not getting the clarity the data should provide. The work here is built around one question: what is actually limiting progress right now.

Ask anything about your protocol
Compounds, stacking, side effects, reconstitution, timing. The answer comes from the research, not a forum.

Before you start
Do you know what your protocol should actually look like before you run it?
Most protocols are built by adding compounds and hoping the stack works. The Protocol Builder checks your foundations first, assigns compound layers based on your actual inputs, runs a conflict map across everything in the stack, and builds a timing framework so nothing overlaps where it should not. One tool. Complete protocol framework.
Build Your Protocol
While you are running
Do you actually know what your protocol is running at right now?
Most researchers know what they injected. Almost none know what their compound is doing between doses. See the curve, the math, and a plain English read of what your protocol is producing. 26 compounds. Free.
Calculate Your Protocol
When one compound is off
Running a compound that is not doing what the research says it should?
Pick the compound you are running, then answer a few quick questions about your dose, your timeline, and what you are seeing. The tool finds the one variable most likely driving your result and points you straight to the research that covers your exact situation. 21 compounds. Free.
Diagnose My Compound
When it stops working
Has your protocol stopped working and you do not know why?
Most stalls come down to one variable that is not being addressed. The Protocol Check identifies where your breakdown is most likely happening before you change anything. Takes about three minutes.

Decision Guides
Questions most researchers cannot answer before they change anything.
Every guide is built around one research decision. Short reads. No filler. Each one walks through the variables that actually matter, what the data shows, and what to look at before adjusting anything in a protocol. All free. One email gets you the full set.

Deep Dives
36 research guides, organized by decision.
There are patterns in this research that most people do not find until they have already spent months going in the wrong direction. Start with the section that matches where you are stuck.
Guides Library
The research behind how protocols are actually built.
Stack compatibility, retatrutide from first dose forward, the growth hormone layer, intake against output, the full protocol framework, and the mitochondrial compounds. Every guide opens as a guest so you can read what it covers before you decide.

Membership
Six products, sold separately. Each one answers a different question, so you only pay for the part you are actually stuck on. Full Access is the only annual plan and it carries all three tools.
Research Search Engine$5.99 / month
Ask anything about your protocol and get a direct research answer in seconds. Unlimited questions, saved history, and any answer exported as a full document.
Stack Visualizer$12.99 / month
Several compounds on one timeline. See where a stack overlaps, where it works against itself, and where the timing needs to move.
Search and Visualizer$15.99 / month
Both tools on one subscription. On their own they are $5.99 and $12.99 a month.
Protocol Builder$39.99 / month
The detailed layer on the free builder. Week by week dosing steps per compound, the reconstitution math, and an overlap map for your stack.
Guides Library$19.99 / month
Seven research guides on protocol design, sequencing, reconstitution, and dose logic. Included with the Protocol Builder and with Full Access.
Full Access Membership$199.99 / year
All three tools on one subscription, plus the full guides library. 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. The only annual plan.
