Testosterone Drops 14% Per Decade After 30 — See Your Personal Hormone Decline Curve
Testosterone drops ~1% per year after 30, growth hormone declines ~14% per decade, and DHT changes accelerate with age. Enter your age to see where your hormones stand — and what can actually slow or reverse the decline.

Sermorelin stimulates your pituitary to produce more of your own growth hormone — the only oral peptide that targets this specific decline.

Common Questions About Hormone Decline
At what age do hormones start declining in men?
Testosterone begins declining approximately 1% per year after age 30, with steeper drops after 45. Growth hormone declines roughly 14% per decade starting around age 25. DHT also decreases with age but 5-alpha-reductase activity changes can accelerate hair follicle sensitivity even as systemic DHT drops.
What are the symptoms of declining growth hormone?
Declining GH typically manifests as slower recovery from exercise, decreased muscle mass, increased body fat (especially abdominal), lower energy, poorer sleep quality, and reduced mental clarity. Sermorelin stimulates the pituitary to produce more of your own GH — addressing the root cause rather than injecting synthetic hormone.
Can hormone decline be slowed or reversed?
Yes — Sermorelin stimulates natural GH production, regular resistance training boosts testosterone, sleep optimization supports both, and NAD+ supplementation supports cellular energy production that declines with age. A comprehensive approach targeting multiple pathways produces the best results.
