Two peptides, one difference that decides it.
Every comparison starts with mechanism rather than marketing: what binds to what, how long it stays active, and how much research sits behind it. Where we cannot ship something, the card says so.
Metabolic & weight
The established single-agonist against the triple — the pairing our own stock actually supports.Read the comparison
- Semaglutide
An amylin analogue against a GLP-1 agonist. We do not stock cagrilintide; customers ask for it by name.In progress
The largest human dataset in the category against the most narrowly defined one.Compare the numbers
Receptor reach against a finished regulatory file.Compare the numbers
One characterised molecule against two co-lyophilised ones — and whose evidence applies to what is in the vial.Compare the numbers
The incretin route or the growth-hormone route — the two are not versions of each other.Compare the numbers
The incretin route against the growth-hormone route — the sharpest split in the catalogue.Compare the numbers
One receptor, two, or three — and how much evidence sits behind each.Read the comparison
Out of stock: Tirzepatide
The head-to-head the three-way article covers only in passing, and the highest-volume pairing in the category.Read the comparison
Out of stock: Tirzepatide
Growth hormone secretagogues
A GHRH analogue against a ghrelin-receptor agonist, and why they are usually paired rather than picked.Read the comparison
Supplying the hormone directly against prompting the body to release its own — the question underneath most of this category.Read the comparison
One vial contains the other — so the question is whether the GHRH component travels with it.Compare the numbers
The same GHRH analogue, with or without a second receptor family alongside it.Compare the numbers
Supplying the hormone, or asking the pituitary to release its own.Compare the numbers
Asking the pituitary to release the hormone, or supplying the hormone itself.Compare the numbers
The two mechanistic classes of secretagogue — GHRH analogue against ghrelin mimetic.Read the comparison
Three GHRH analogues separated mostly by half-life and by how much clinical data exists.Read the comparison
Out of stock: Sermorelin
Injectable and selective, against oral and long-acting with appetite effects.Read the comparison
Out of stock: MK-677
Acting downstream of growth hormone versus acting on its release.Read the comparison
Out of stock: IGF-1 LR3, MK-677
The most potent ghrelin-receptor agonist against the most selective one, and what potency costs.Compare the numbers
Out of stock: Hexarelin
Recovery & tissue repair
Angiogenesis and gut-derived repair against actin regulation and cell migration.Read the comparison
Whether the two recovery peptides are genuinely complementary or simply sold together.Read the comparison
Tissue-level repair signalling against the systemic growth-hormone axis.Compare the numbers
Fifteen amino acids with a preclinical file against 191 with a clinical one.Compare the numbers
A local repair signal against an endocrine one, and which body of evidence covers the vial.Compare the numbers
Cytoskeletal repair work against endocrine pharmacology — same shelf, no shared mechanism.Compare the numbers
A protein fragment acting where it is placed, against a hormone acting everywhere.Compare the numbers
Soft-tissue repair against dermal remodelling — both called repair, different tissue and different evidence.Compare the numbers
Longevity & cellular
Restoring a metabolic cofactor against supplying a hormone — and only one of them is a peptide.Compare the numbers
A cellular cofactor against an endocrine signal — the two answers people give to the same vague question.Compare the numbers
Cellular energy metabolism against telomere and circadian signalling — two different theories of ageing.Compare the numbers
Out of stock: Epithalon Premium
Two mitochondrial approaches: replenishing a cofactor against a mitochondrial-derived peptide signal.Compare the numbers
Out of stock: MOTS-c
Cognitive & sleep
Sleep architecture against daytime anxiety, and why that difference decides which one fits.Compare the numbers
A compound whose literature is about sleep, against one whose literature is about growth hormone.Compare the numbers
Anxiolytic against stimulatory — the two are searched together almost every time.Read the comparison
Out of stock: Semax
Skin
Copper-peptide remodelling against general tissue repair, applied to skin.Read the comparison
Dermal matrix work against melanocortin signalling — two questions, not two answers.Compare the numbers
Sexual health
A melanocortin agonist selected for one effect against one that produces several.Read the comparison
Out of stock: PT-141, Melanotan II
Selective against broad melanocortin binding, and what that predicts about side effects.Read the comparison
Out of stock: Melanotan II
