Peptide Comparisons
Detailed head-to-head analysis of commonly compared peptides. Each comparison covers key differences, when to consider each option, and whether they can be stacked.
The two most prescribed weight loss peptides compared. Semaglutide (Ozempic/Wegovy) is a GLP-1 agonist, while tirzepatide (Mounjaro/Zepbound) is a dual GIP/GLP-1 agonist producing greater average weight loss.
The two most popular tissue repair peptides compared. BPC-157 promotes local healing through angiogenesis, while TB-500 works systemically through actin regulation and cell migration. They are commonly stacked together.
Two popular growth hormone secretagogues compared. Ipamorelin acts through ghrelin receptors (GHRP), while sermorelin acts through GHRH receptors. They work through different pathways and are often combined.
Two Russian-developed nootropic peptides compared. Semax is primarily a cognitive enhancer (focus, memory, BDNF), while Selank is primarily an anxiolytic (anxiety reduction, calm focus). Both are nasal peptides often used together.
Two popular anti-aging skincare peptides compared. GHK-Cu stimulates collagen production and tissue repair from within, while Argireline reduces wrinkles by relaxing facial muscles (topical "Botox alternative").
Current champion vs next-generation challenger. Semaglutide is the FDA-approved GLP-1 agonist, while retatrutide is Eli Lilly's investigational triple agonist (GLP-1/GIP/glucagon) showing even greater weight loss in trials.
Two anti-aging peptides with fundamentally different approaches. Epitalon activates telomerase to maintain telomere length, while FOXO4-DRI selectively kills senescent cells. Both target core mechanisms of biological aging.
The most commonly combined GH peptide pair, also compared as alternatives. CJC-1295 is a GHRH analog (amplifies GH release), while ipamorelin is a GHRP (triggers GH release). Together they are synergistic.
