During molecular dynamic simulations with GLP-1 bound, the N-terminal helix was oriented vertically (black and blue arrows), whereas in the apo-form the ECD N-terminal helix was more dynamic and experienced both open and closed conformations (this is analogous to the suggested ECD dynamics for the glucagon receptor)

However, several considerations apply: Melanocortin receptor agonists could theoretically fall under prohibited substance categories if evidence of performance enhancement emerged Athletes should consult with sports medicine physicians and anti-doping officials before use Lack of current prohibition does not indicate WADA endorsement or recommendation Future regulatory status could change based on emerging evidence Availability and Compounding Considerations FDA-approved Vyleesi available only by prescription through licensed pharmacies Some compounding pharmacies offer PT-141, though quality, purity, and dosing accuracy may vary Research-grade PT-141 available from peptide suppliers for laboratory use only International regulatory status varies by country Research Classification: PT-141 is available in FDA-approved form (Vyleesi) for one specific medical indication by prescription only
