Peptides for Muscle and Strength
Beginner peptide guide
The peptides people research for muscle mostly raise your own growth hormone or work through IGF-1, the downstream growth signal. They support training and recovery rather than replace it, and the gains come from the work you put in next to them.

• GH secretagogues (CJC-1295, Ipamorelin, MK-677) raise your own growth hormone.
• IGF and follistatin peptides act on the growth and muscle-building pathways more directly.
• Training, protein, and sleep still drive the results, these are support.
