Past that window, peptide concentration drifts downward through chemical degradation pathways even though the bacteriostatic water's benzyl alcohol still suppresses microbial growth

Instead of supplying growth hormone directlya strategy associated with safety concerns and unpredictable effectstesamorelin prompts the bodys own pituitary gland to release growth hormone in a pulsatile, physiologic pattern (Theratechnologies, 2025)

These compounds can neutralize free radicals and reduce oxidative stress, mechanisms implicated in the pathogenesis of several neurodegenerative diseases, including Alzheimers disease and Parkinsons disease (404, 405)

Key properties: Stimulates GH release from the pituitary (not the hypothalamus) Does not significantly raise cortisol or prolactin Short half-life (~2 hours) produces a sharp, pulsatile GH release Does not block somatostatin (the hormone that inhibits GH release) Selective for GH minimal effect on other hormones The selectivity is what makes ipamorelin the preferred GHRP for most protocols

They are convenient for daily use and can help sustain antioxidant support
