Structured tracking for a protocol you already run

Not medical advice, and not a place to get compounds

This module does not tell you what to take or how much. It does not source, sell, or recommend compounds, and nothing in the catalog or the interaction check substitutes for a conversation with a physician or endocrinologist. It exists for people already using these compounds under their own medical guidance, who want a better record than a note on their phone.

Every flag it raises is informational, never prescriptive, the same line MuscleBuddy holds on supplements and bloodwork. If a flag surfaces something that concerns you, the next step is a qualified clinician, not the app.

Cycle phases and post-cycle therapy, with a shape

A phase gives a protocol its outline: a blast, a PCT phase, a recovery phase, a contest-health phase, or one you define yourself, each with a start date and, once you close it, an end date. The protocol attached to that phase is the plan: each item names a compound, its dosage, unit, and frequency, and optionally its route and schedule. Your daily log is what actually happened.

Anyone who has tried to reconstruct a cycle from memory three months later knows why those are two different records. The protocol is the plan, the log is the reality, and keeping both is how you see where they came apart.

Compounds you run continuously (HRT and TRT, most often) are tracked as an ongoing baseline instead of a time-boxed cycle. The same module holds a defined blast-and-PCT and an indefinite maintenance protocol without forcing either into the other's shape.

Interaction and contraindication flagging

Every compound in the catalog carries interaction metadata: warnings, meaning things worth knowing when you stack it, and contraindications, meaning combinations flagged more seriously. Check a stack and the module compares every pair in it, raising any shared contraindication as a high-severity flag and surfacing the warnings that apply to the stack as a whole. Anything flagged as a controlled substance carries an explicit informational-use-only marker wherever it appears.

This is not a clinical interaction database and does not pretend to be one. It's a second look at a stack you already assembled: the check a careful person runs by hand, run every time instead of some of the time.

How an active compound shows up elsewhere

An active compound doesn't stay in the health module. MuscleBuddy watches your active stack for a few specific categories and raises a note in the place the compound actually touches. An active GLP-1 agonist flags appetite suppression that may affect how easily you hit your calories, in nutrition. An active anabolic or SARM flags that volume tolerance may run high and recovery is worth watching, in training. An active peptide flags that bloodwork monitoring is worth keeping up, in health. An active controlled substance carries its informational-use-only marker everywhere the stack appears.

These are notes, not adjustments. Nothing rewrites your program because of a flag. You see it and you decide what it means, the same as you would with a dip in your recovery score or a marker outside its range.

Plain-language explanations, generated on demand

For any compound in the catalog you can pull a short explanation of what it is, how it works, and what's worth being careful about, generated against the catalog entry rather than served from a static blurb. Entries carry citations to the source literature, so you can go and read it yourself.

It's a starting point for understanding something you are already taking. It is not a recommendation to take it, and it is not dosing guidance.
