Peptide Classification: Main Groups and How They Work
Published: 2026-03-02 11:25:00 | PEPTEX Research

Peptides are a heterogeneous group. Each class works with its own body system, solves its own tasks and has its own logic of use. These classes are described below:GHRH (Growth Hormone Releasing Hormones)
This class mimics the body's natural signal, stimulating the pituitary gland to produce growth hormone on its own. It doesn't cause a sharp spike, but supports the natural pulsatile rhythm of secretion.
Representatives: CJC-1295, Sermorelin, Tesamorelin
Used for: muscle gain, fat loss, recovery, anti-agingGHRP / Secretagogues
These work a bit differently, through ghrelin receptors, also stimulating growth hormone release, but additionally affecting appetite and GI motility. Often used in combination with GHRH.
Representatives: Ipamorelin, GHRP-2, GHRP-6, Hexarelin
Used for: enhanced growth hormone release, improved recovery, appetite stimulation (GHRP-6)GLP-1 (Glucagon-like peptide-1)
This class of peptides regulates blood sugar levels, suppresses appetite and slows gastric emptying. GLP-1 became the predecessor of other weight loss drugs.
Used for: weight loss, blood sugar control in type 2 diabetes, cardioprotectionHealing peptides (BPC-157, TB-500)
These are among the most popular types of peptides in sports and regenerative medicine. They accelerate tissue regeneration, reduce inflammation, restore tendons, ligaments and mucous membranes. Applied directly to the injury site.
Representatives: BPC-157, TB-500
Used for: recovery after injuries, treatment of joints and ligaments, GI protection (BPC-157)Skin peptides
This group stimulates collagen synthesis, accelerates healing, reduces inflammation and slows age-related changes. Can be supplied as blends, like KLOW or GLOW, including not only GHK-Cu for example, but also related peptides that work great in synergy.
Representatives: GHK-Cu, Matrixyl (Palmitoyl Tripeptide-1), Argireline
Used for: skin rejuvenation, wound healing, improved tone and elasticity.Sleep peptides
This group of peptides affects the depth and quality of sleep, acting through the body's own mechanisms.
Representatives: DSIP, Epithalon
Used for: improving sleep quality, normalizing circadian rhythms, anti-aging (Epithalon)
