The Science of Looking and Feeling Your Best After 30

If you're a man over 30 who trains consistently, you've noticed the shift. Recovery takes longer. Body composition changes despite the same effort. Energy and drive aren't what they were at 25. This isn't in your head — it's endocrinology.

Growth hormone production declines ~1% per year after 30. Testosterone drops ~1–2% annually after 35. These hormonal shifts compound over decades, affecting muscle maintenance, fat metabolism, sleep quality, libido, and overall vitality. The good news: the science of managing these changes — through training optimization, targeted supplementation, and emerging clinical therapies — is advancing rapidly.

Ripped Science covers this landscape: HGH secretagogues, testosterone optimization, the emerging world of peptide therapy, and the foundational training and recovery strategies that make everything else work better.
