Key Takeaways on Peptides for Muscle Growth GH secretagogues drive the muscle growth response: CJC-1295 and Ipamorelin work by stimulating the pituitary to release growth hormone in a physiological pulsatile pattern, which drives IGF-1 production and protein synthesis in skeletal muscle

Therefore, even with a similar genome, cells have potentially numerous physical differences [35]
