In this episode, I explain the major categories and types of peptides currently in use for therapeutic purposes. I discuss peptides for improving tissue rejuvenation and repair, promoting longevity, improving muscle growth and fat loss, and boosting mood, vitality, and libido. I explain the biology of how these peptides work and both their potential benefits and risks. I also discuss peptide sourcing, dosages, cycling, routes of administration, and how peptides work in combination. This episode will help you better understand the rapidly expanding landscape of peptide therapeutics and how to evaluate if specific peptides might be advantageous towards achieving your physical or mental health goals.
