Stack Builder
Start with a real health picture, not a guess
The Stack Builder begins the way a good annual checkup does: your goals, your medications and supplements, and recent blood work if you have it. That context grounds a research-cited peptide stack you can review with a licensed provider.

What the intake covers
-
About you
Date of birth, biological sex, and any diagnosed conditions. This is the baseline any careful review starts from.
-
Medications & supplements
Everything you currently take, so nothing gets considered in a vacuum.
-
Goals & symptoms
What you want to improve and what you are trying to fix, in your own words.
-
Blood work (optional)
Upload recent labs as a PDF or image if you have them. Entirely optional and skippable.
Your health data stays yours
Everything you enter is encrypted at rest. You can delete your health data at any time, from inside the intake. It is never sold, and it is never used for advertising, audience building, or profiling.
One exception, and it is how the tool works: when you ask for a stack, your intake answers and any blood work you uploaded as a PDF, JPG, PNG, or WebP file go to two outside companies: OpenRouter, a routing service that carries the request, and the AI model provider whose model generates it. That model provider is currently Anthropic's Claude. Your date of birth, name, email address, phone number, and state are not sent.
The Stack Builder is an educational tool. It does not diagnose, treat, or prescribe. It prepares a better conversation with a licensed provider. Using it is subject to our Terms of Use.
