Growth hormone levels decline with age, which is why supporting the GH axis has become a focus for longevity-minded individuals

published in Frontiers in Physiology confirmed that BPC-157 dose- and time-dependently increased GHR expression in isolated rat Achilles tendon fibroblasts at both mRNA and protein level, and that GH added to BPC-157-treated fibroblasts produced significant, dose-dependent increases in cell proliferation establishing GHR upregulation as a specific molecular mechanism through which BPC-157 enhances local tissue sensitivity to growth hormone signalling
