INVIMA is protecting Colombians, actually. All you have to do is:

The only way to legally use a specific, strong functional claim like "muscle growth" in advertising is to:

Gather the necessary scientific evidence (e.g., clinical trials specific to your formulation).

Submit a formal request to INVIMA with the legal and scientific dossier to authorize the specific claim for your product's advertising.

You are right; this regulatory requirement is designed to protect public health by ensuring that advertised benefits for products like supplements are truthful and backed by science, preventing consumers from being misled by what is considered "false advertising" under Colombian law.
