The difference is medical oversight and pharmacy quality.
Gray-market "research use only" peptides come with no physician, no dosing guidance, and no quality accountability. They are not intended for human use, and there is no one reviewing whether they are safe or appropriate for you.
Every Live Vital protocol is physician-prescribed by Dr. Taylor after a medical intake, and it is prepared by a licensed US compounding pharmacy that is regulated by state boards of pharmacy and required to comply with applicable USP standards. You also get a personalized protocol, administration guidance, and an ongoing relationship with a care team you can message through the portal.
In short: this is prescription medicine delivered through telehealth, not a product you buy off a website.
