A plain-English primer on what peptides are, how the categories break down, and the most common questions we hear, so you walk into any conversation informed.
Peptides are small molecules made of 2 to 50 amino acids linked together, short chains of the same building blocks that make up proteins. In the body, they act as signaling molecules, directing cells to carry out specific tasks.
Because they closely resemble proteins and can interact precisely with cellular receptors, peptides have become a focus of research across areas like tissue repair, metabolism, energy, skin health, and hormonal regulation. The categories below group them by what they're most commonly studied for.
Studied for signaling fullness, slowing stomach emptying, and supporting blood-sugar balance.
Growth-hormone–releasing peptides researched for lean muscle, recovery, and sleep.
Explored for healing of tissues, tendons, and ligaments and for a faster return to activity.
Linked to mitochondrial function and overall vitality.
Researched for restful sleep and circadian-rhythm support.
Studied for supporting the body's defenses and immune regulation.
Explored for libido and sexual wellness in men and women.
Researched for collagen, elastin, wound healing, and age-related concerns.
Examined for cognition, memory, and healthy-aging pathways.
Studied for mood, focus, and stress resilience.
A good consultation leaves you with better questions. Here are a few worth bringing to your licensed physician before considering any therapy.
What is this peptide used for, and what does the research actually show?
What benefits should I realistically expect, and over what timeframe?
What side effects or precautions should I know about?
How would we monitor my progress and adjust along the way?
