Mechanism-focused overviews grounded in peer-reviewed literature. Each article traces the pharmacological evidence behind the compounds we carry.
BPC-157 (Body Protection Compound-157) is a synthetic pentadecapeptide derived from a protective protein found in gastric juice. Decades of preclinical research point to a broad regenerative profile spanning tendon, ligament, muscle, gut, and neural tissue.
Tirzepatide's dual agonism at GLP-1 and GIP receptors gives it a mechanistically distinct profile from semaglutide's selective GLP-1 activity. Here we compare receptor pharmacology, published trial outcomes, and the synergistic mechanisms of the twincretin class.
GHK-Cu is a naturally occurring tripeptide-copper complex with remarkable research activity: it stimulates collagen and glycosaminoglycan synthesis, modulates TGF-β signaling, suppresses NF-κB inflammatory cascades, and regulates gene expression in aging tissue.
Ipamorelin and CJC-1295 (No DAC) represent two complementary classes of growth hormone secretagogues — a ghrelin receptor agonist and a GHRH analog — that act on distinct receptor populations to produce synergistic, pulsatile GH release.
Epithalon (Ala-Glu-Asp-Gly) is a synthetic tetrapeptide best known for its ability to activate telomerase and extend telomere length in somatic cells — a finding with significant implications for cellular aging research.
TB-500 is a synthetic peptide fragment corresponding to the active region of Thymosin Beta-4 (Tβ4), a ubiquitous protein with a central role in actin dynamics, cell migration, and tissue repair.
Retatrutide (LY3437943) is a single molecule that simultaneously agonizes the GLP-1, GIP, and glucagon receptors. Phase 2 data published in 2023 reported dose-dependent body-composition endpoints, establishing triagonism as a distinct pharmacological class.
The Glow Blend pairs GHK-Cu and TB-500 in a combination that addresses tissue repair and skin regeneration through complementary, non-redundant mechanisms — collagen induction and gene-level remodeling from GHK-Cu, cell migration and angiogenesis from TB-500.
A research-focused summary of recently published literature across the compounds in our catalog, from large late-stage GLP-1 programs to preclinical work on regenerative and mitochondrial peptides, with primary sources cited throughout.
Semax and Selank are synthetic regulatory neuropeptides developed in Russian neuroscience as stable analogs of endogenous sequences. This overview surveys their receptor and neurotrophic mechanisms as studied in preclinical CNS models.
MOTS-c is one of a small class of mitochondrial-derived peptides encoded within mtDNA. This overview surveys its origin, AMPK-linked signaling, and the preclinical models in which it is studied.
KPV is the C-terminal tripeptide of α-melanocyte-stimulating hormone. This overview surveys its melanocortin-independent modulation of inflammatory signaling and the epithelial-transport research that distinguishes it.
NAD+ is a central redox coenzyme and a substrate for sirtuins and PARPs. This overview surveys the pathways in which it is studied, from the salvage cycle to mitochondrial and DNA-repair research.
DSIP is a small neuropeptide first isolated for its association with delta-wave EEG activity. This overview surveys its neuroendocrine research profile and the mechanistic questions that remain open.
Tesamorelin is a stabilized analog of growth-hormone-releasing hormone. This overview surveys its secretagogue mechanism, the GH/IGF-1 axis it engages, and the structural changes that extend its stability.
A practical, laboratory-focused guide to interpreting peptide COAs without confusing purity, identity, content, or method suitability.
Modern synthetic peptides are commonly assembled one amino acid at a time on a solid support. Here is what each stage contributes, and where impurities can arise.
Lyophilization is more than making a powder. It is a controlled freezing and drying process whose outcome depends on formulation, temperature, pressure, and residual moisture.
Peptides do not share one universal stability profile. Their sequences create different vulnerabilities to oxidation, deamidation, hydrolysis, adsorption, and aggregation.
