The Apex Protocol
GLP-3 RT
Apex marks the highest point and protocol the most exacting procedure: the flagship of the collection, held to the strictest standard Obsidian sets.
$219.00
GLP-3 RT is studied for its interaction across three receptor pathways simultaneously, a structural complexity that has made it one of the most closely examined compounds in current metabolic peptide research. Laboratories continue to investigate its multi-receptor behavior as a distinct category within GLP-1 adjacent science.
Every batch entering the Obsidian collection is tested twice. First by the manufacturer. Then independently, by an accredited U.S. laboratory, before it ever earns the Obsidian name. Nothing ships on a single signature.
