How to Choose the Right Compound for Your Injury
1. Identify Your Primary Injury Type
Different compounds show varying efficacy across injury categories. Wound healing compounds (zinc, magnesium, vitamin D3) differ from compounds targeting muscle recovery (curcumin, collagen peptides) or neurological injury (cerebrolysin, cortexin).
2. Assess Evidence Consistency
Even within Tier 3, some compounds show more consistent results across multiple studies. NAC, magnesium, and zinc have been replicated across multiple human trials in similar injury contexts. Compounds like ibutamoren show inconsistent results even in their primary indication.
3. Consider Safety and Drug Interactions
Zinc supplementation above 40 mg daily may cause copper depletion with long-term use. Curcumin may interact with blood thin
