A muscle gain protocol is a stack architecture template for testing whether a stable supplement roster supports a hypertrophy or strength block without obscuring the training variables that drive most of the outcome. It fixes the stack, timing, review window, and proxy pair so the user is not changing supplements every time a workout feels better or worse.
Training context comes first
The protocol is only readable when the training block is readable. A changing split, changing effort target, changing food intake, and changing stack create too many explanations for the same result.
Unfair treats the stack as one layer inside a larger block. The protocol therefore starts with a stack goal, a named training proxy, and a review cadence that fits the training plan.
Stack shape
The stack uses a small core tier and a narrower optional tier. Core items are stable choices the user already tolerates. Optional items are tested one at a time, with a written reason for entry and a written exit rule.
Pre-training additions belong in a pre-training dose window rather than scattered across the day. Recovery-oriented additions belong in a separate window so the user can tell whether the change is tied to training output, recovery, or sleep.
Proxy pair
The primary proxy can be total weekly volume, estimated top-set strength, bodyweight trend under stable intake, or another training metric collected the same way each week. The secondary proxy should protect against over-reading the primary, such as soreness, sleep quality, or readiness.
A useful protocol does not chase every good session. It reads block-level movement and compares it with adherence, training load, and recovery markers.
Review rules
The review asks three questions in order. Was the training block consistent enough to read? Was the stack taken with enough adherence to matter? Did the proxy pair move in a direction that justifies keeping the optional item?
That sequence matches the broader stack composition idea: the roster is judged by its role in the stack, not by a single impressive workout.
How this appears in Unfair
In Unfair, a muscle gain protocol would prefill the builder with a training-focused goal, pre-training and recovery windows, and a block review that separates core items from optional tests. The app can then ask whether to keep, drop, or retest the optional tier without rewriting the whole stack.
Clinical safety note
A muscle gain protocol is not a medical or athletic-performance prescription. New pain, unusual shortness of breath, fainting, persistent sleep disruption, or major changes in blood pressure should pause stack changes and prompt clinician review.
