They found that the combination of these growth factors displayed a more significant maximum load and tensile stress and inhibited scar formation compared to the IGF-1 alone group, suggesting that combination of IGF-1 and TGF- is more effective than IGF-1 alone in the treatment of tendon injury (Xiang et al., 2018)

IGF-1 Upregulation Downstream Anabolic Signaling Both peptides indirectly stimulate insulin-like growth factor-1 (IGF-1) production through sustained growth hormone elevation: Growth hormone binds to hepatic GH receptors activating JAK-STAT signaling pathways Increased transcription of IGF-1 gene in liver tissue Elevated plasma IGF-1 levels mediate anabolic effects in muscle, bone, and adipose tissue IGF-1 provides negative feedback regulation preventing excessive growth hormone secretion Studies report IGF-1 increases of 1.5- to 3-fold for 9-11 days following CJC-1295 administration, with the ipamorelin combination providing more sustained elevation
