KPV (Lys-Pro-Val) is the C-terminal tripeptide of alpha-MSH studied for anti-inflammatory activity in gut epithelial models. Unlike full-length alpha-MSH, KPV acts via PepT1 transport — not MC1R/cAMP — to inhibit NF-kB and MAP kinase at nanomolar concentrations. DSS colitis models show ~50% MPO reduction.

Tesamorelin is a full 44-amino-acid GHRH analog with an N-terminal hexenoyl modification conferring DPP-4 resistance. Phase III data in HIV-associated lipodystrophy demonstrated −27.8 cm² VAT reduction vs. +5.1 cm² in placebo. Research models characterize GHRH-R → pulsatile GH → hepatic IGF-1 → visceral lipolysis pathway. Independent research compilation for scientific and educational reference only.
Thymosin Alpha-1 (Tα1) is a 28-amino-acid thymic peptide studied for TLR-9 agonism on plasmacytoid dendritic cells. Preclinical models document Th1 cytokine polarization (↑IL-12, IFN-γ; ↓IL-10), NK cell activation, and IDO pathway modulation. Independent research compilation for scientific and educational reference only.
SLU-PP-332 is a synthetic pan-ERR agonist studied as an exercise mimetic in preclinical models. Rodent data shows 70% increase in treadmill endurance, 10× less fat gain in obese models, and cardiac function improvement in heart failure models — all ERRα-dependent. Thin but active literature; 6-8 primary papers as of 2026. Independent research compilation for scientific and educational reference only.
SS-31 (Elamipretide) is a Szeto-Schiller tetrapeptide that selectively binds cardiolipin at the inner mitochondrial membrane (KD = 1.87 μM). Preclinical models document cristae preservation, ETC supercomplex stabilization, and restored ATP production in aging and ischemia models.

Essential information about our research-grade peptides and quality standards.
Peptides are short chains of amino acids linked by peptide bonds, typically consisting of 2-50 amino acids. They serve as the building blocks of proteins and play crucial roles in biological processes.
Research peptides are synthesized versions of naturally occurring peptides, manufactured to precise specifications for use in scientific studies.
Peptide purity refers to the percentage of the target peptide present in a sample, determined by third-party analytical testing and reported on the batch Certificate of Analysis.
Higher purity is critical for research because impurities can interfere with experimental results and compromise the reproducibility of studies.
