Muscle and Fat (Insulin Sensitivity): GLP-1 RAs enhance glucose uptake in muscle and adipose tissue via the PI3K/Akt pathway, improving overall insulin sensitivity (Zheng et al., 2024)
Activation of nucleus tractus solitarius GLP1 neurons leads to an attenuation of metabolic rate and a reduction of food consumption in both fed and fasted states in mice (Table 1) (Cheng et al., 2020
Product quality
Their normal function is to regulate the microtubule assembly, which helps axonal transport, neuronal outgrowth, and polarity [26, 43, 53]
Since 1ml is typically 100 units on an insulin syringe, each unit would contain 10 mcg of IGF-1 LR3 (1000 mcg / 100 units)
While Western clinical trial data on the specific combination is limited, the individual evidence bases for each peptide are substantial, and their mechanisms are complementary rather than redundant
