Cerebrolysin is a process-defined peptide mixture, not a single molecule. A review of the blinded rodent MCAO record, the function-versus-infarct dissociation, and what neurotrophin measurement actually shows.
Selank and Semax are studied together in preclinical models for complementary mechanisms — enkephalinase inhibition and GABAergic signaling versus BDNF induction. A review of the rodent and in vitro record.
Sermorelin (GHRH 1-29) is the shortest fully active GHRH fragment, studied for pulsatile GH release via GHRH-R/Gαs/cAMP/CREB signaling. Rodent models show pulsatile delivery doubles GH mRNA while continuous infusion has no effect. GHRH-R mRNA declines significantly in aged rat pituitary.

BPC-157 and TB-500 (Thymosin Beta-4) are two peptides studied separately in tissue repair models with distinct mechanisms: BPC-157 via NO/eNOS/VEGFR2 signaling; TB-500 via G-actin sequestration and directed cell migration. No published co-administration studies exist. Independent research compilation for scientific and educational reference only.
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.

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.
