Why Don't I Build Muscle? Your Genetics May Have Answers
Struggling to build muscle despite consistent training? Genetics may be the missing variable. MSTN, ACTN3, IGF1, GHSR, and VDR variants all influence how your body responds to resistance training stimulus — from hypertrophy ceiling to anabolic signal strength to fiber architecture. The Precision Peptide Genetic Test analyzes 15 Muscle Growth insights across 14 pathways, 49 peptides, and 150+ genetic insights.
ACE Gene: Endurance vs Power Athlete Genetics
The ACE gene’s I/D polymorphism is one of the most replicated findings in sport genetics — separating endurance-optimized physiology (I allele) from power-optimized physiology (D allele) through cardiovascular architecture rather than fiber structure alone. The Precision Peptide Genetic Test analyzes ACE as one of 15 Muscle Growth insights across 14 pathways, 49 peptides, and 150+ genetic insights.
