The table below compares kisspeptin to major peptide classes across mechanism, receptor target, half-life, and primary research applications. Kisspeptin-10 Stimulates GnRH neuron depolarization to trigger LH/FSH release GPR54 (KI…
HPLC (High-Performance Liquid Chromatography) Purity percentage, deletion sequences, aggregates 0.1% relative area $150–$300 Standard verification for all peptides; primary purity metric Required baseline. Without HPLC data, puri…
Most research peptides function through receptor binding or signaling modulation. BPC-157 activates VEGF (vascular endothelial growth factor) pathways to promote angiogenesis and tissue repair. Growth hormone-releasing peptides (…
VIP (Vasoactive Intestinal Peptide) VPAC1/VPAC2 receptor agonist; inhibits NF-κB and pro-inflammatory cytokines Neuroinflammation, autoimmune disease, sepsis, circadian rhythm Subcutaneous, IV, intranasal ~2 minutes (plasma); eff…
503B-Registered Supplier HPLC-verified ≥98% per batch <1.0 EU/mg documented on CoA Full synthesis batch tracking Required for reproducible research. Only option with verifiable quality control Generic Peptide Vendor Self-reported…
Storage Temperature Room temp (15–25°C) acceptable 2–8°C refrigeration required −20°C freezer required Temperature excursions above 8°C denature reconstituted peptides irreversibly. Neither appearance nor potency testing at home …
GLP-1 receptor agonists (semaglutide, tirzepatide, liraglutide) belong to the incretin mimetic class. They bind GLP-1 receptors in pancreatic beta cells, gut tissue, and hypothalamic satiety centers to reduce appetite, slow gastr…
Growth hormone secretagogues. Ipamorelin, GHRP-2, GHRP-6, CJC-1295. Bind to ghrelin receptors (GHS-R1a) in the pituitary gland, triggering pulsatile release of endogenous growth hormone. That release elevates plasma IGF-1 (insuli…
BAC water isn't a research peptide. It's the sterile solvent that makes lyophilised peptides injectable. And confusing the two is the single most common error we see in peptide research protocols. According to a 2023 review publi…
Lipo-C (Lipotropic Formulation) Substrate provision for phosphatidylcholine synthesis Hepatocyte methionine cycle and Kennedy pathway enzymes Stable at 2–8°C; tolerates brief ambient exposure Hepatic steatosis models, methylation…
Oxytocin acts as a cyclic nonapeptide hormone synthesized in the hypothalamus and released into circulation or directly into brain regions via axonal projections. Its primary binding target is the oxytocin receptor (OXTR), a G-pr…
VIP binds VPAC1 and VPAC2 receptors primarily expressed on immune cells, vascular endothelial cells, and neurons. Triggering cAMP elevation that inhibits pro-inflammatory transcription factors like NF-κB and AP-1. This is mechani…
Molecular Weight ~527 Da ~4113 Da ~4813 Da ~3751 Da Small-molecule structure allows oral bioavailability; peptides require injection Route of Administration Oral (daily) Subcutaneous (weekly) Subcutaneous (daily) Oral route intro…
ARA-290 EPOR-βcR tissue-protective receptor activation Neuropathy, autoimmune cytoprotection, metabolic stress 1–8mg SC 3×/week 8–12 hours Anti-apoptotic, not regenerative. Best for cell survival under metabolic stress BPC-157 VE…
Cartalax (bioregulator) Gene transcription modulation in gastric mucosa Stomach lining epithelium Oral or subcutaneous Gastric ulcer healing, mucosal barrier restoration, age-related digestive decline Tissue-specific with no syst…
ARA-290 binds to a receptor complex most peptides don't interact with. The heterodimeric tissue-protective receptor formed by the erythropoietin receptor and the beta common receptor (EPOR-βcR). This is fundamentally different fr…
5-Amino-1MQ and GLP-1 receptor agonists (semaglutide, tirzepatide, liraglutide) both produce fat loss in research models—but through entirely different biological cascades. GLP-1 agonists bind to GLP-1 receptors in the hypothalam…
Tirzepatide (Mounjaro, Zepbound) is also a dual agonist, but it targets GIP (glucose-dependent insulinotropic polypeptide) and GLP-1 receptors instead of glucagon. GIP enhances insulin secretion and promotes fat storage in adipos…
Direct head-to-head trials between mazdutide and other peptides are limited, but cross-trial comparison using equivalent BMI populations provides actionable insight. The table below compares mean weight reduction, trial duration,…
Here's the honest answer: SS-31 isn't a better or worse peptide than BPC-157, thymosin beta-4, or growth hormone secretagogues. It solves a completely different problem. Comparing SS-31 to GHRPs is like comparing a structural eng…
