Precision Standards for Peptide Research
American Top Lab is an analytical biotechnology provider specializing in ultra-pure peptide reagents. Every single vial is cataloged, verified for mass integrity, and searchable on our open analytical authentication network.
Certified Analytical Purity
Synthesized via Solid Phase Peptide Synthesis (SPPS) with rigorous multi-column purification ensuring absence of truncated sequences and heavy metal contaminants.
HPLC & Mass Spec Validated
We do not rely on standard internal claims. Each production batch undergoes independent High-Performance Liquid Chromatography and Electrospray Ionization Mass Spectrometry.
Direct Batch Traceability
Every vial and carton is equipped with a digital batch signature and dual-layer scratch-off PIN. Research teams can instantly verify serialization and COA logs.
Peptides Research Portfolio
Ultra-pure laboratory reference standards synthesized via SPPS with RP-HPLC and mass spectrometry certification.
Retatrutide (Reta)
Triple GIP / GLP-1 / Glucagon Receptor Agonist
Engineered tri-agonist activating GIP, GLP-1, and Glucagon receptors concurrently. Elevates hepatic mitochondrial energy oxidation while suppressing metabolic intake signaling.
Tirzepatide
Dual GIP / GLP-1 Receptor Agonist
Synthetic dual incretin peptide enhancing glucose-dependent insulin dynamics, gastric transit slowing, and central hypothalamic satiety modulation.
Semaglutide
Selective Long-Acting GLP-1 Receptor Agonist
Modified GLP-1 analog with Aib-8 substitution and hydrophilic spacer fatty diacid for high albumin binding affinity and extended in-vitro stability.
BPC-157 (Pentadecapeptide)
Angiogenic & Cytoprotective Repair Pathways
Stable 15-amino acid sequence that upregulates VEGFR2 (Vascular Endothelial Growth Factor Receptor 2) and triggers the FAK-paxillin focal adhesion pathway.
TB-500 (Thymosin Beta-4)
Actin Regulation & Cellular Tissue Remodeling
Synthetic fraction of the actin-sequestering protein Thymosin Beta-4. Binds monomeric G-actin, accelerating endothelial migration and tissue remodeling.
