Peptide Popularity & Research
What Are Peptides?
Peptides are short chains of amino acids that act like messengers in the body. They help regulate hormones, support healing, and promote healthy skin, muscles, and brain function.
Popular Peptides & What They Do
Skincare & Anti-Aging
Matrixyl: Boosts collagen to smooth fine lines and firm skin.
Copper Peptide (GHK-Cu): Helps heal skin and reduce inflammation.
Argireline: Softens expression lines by relaxing facial muscles.
Collagen Peptides: Improve skin hydration, elasticity, and joint comfort.
Muscle & Recovery
CJC-1295 + Ipamorelin: Support growth hormone release for muscle repair.
MK-677: Helps preserve muscle during dieting.
BPC-157 & TB-500: Aid in healing tendons, muscles, and gut lining.
Metabolic & Weight Support
GLP-1 Agonists (Semaglutide, Liraglutide): FDA-approved for diabetes and weight loss.
Tirzepatide: Dual-action peptide showing strong weight loss results.
AOD9604 & HGH Fragment 176-191: Early-stage peptides studied for fat burning.
Sexual Health
PT-141: FDA-approved to support libido and sexual function.
Kisspeptin: Being studied for its role in arousal and mood.
Immune & Healing Support
Thymosin α-1: Used in immune-related conditions like hepatitis and sepsis.
Solnatide: Inhaled peptide studied for lung health and COVID-related recovery.
Advanced & Trial-Stage Peptides
Ularitide: Studied for heart and kidney failure.
NA-1, CN-105: Neuroprotective peptides in stroke trials.
Pemziviptadil & Zilucoplan: Target pulmonary and autoimmune conditions.
Cancer PDCs: Peptides that deliver drugs directly to tumors.
What the Research Says
Collagen peptides improve skin hydration and elasticity.
BPC-157 shows strong healing effects in animal studies.
CJC-1295 boosts growth hormone levels for days after injection.
Peptides for Alzheimer’s and Parkinson’s are in mid-stage trials.
Final Takeaway
Peptides are making waves in skincare, recovery, metabolism, immunity, and even cancer research. Some are FDA-approved and widely used—others are still being studied. But the science is clear: peptides offer targeted support with fewer side effects and exciting potential.
