What's not represented

  • · Fitness and bodybuilding communities driving gray-market demand
  • · Health insurance providers managing the cost of widespread peptide prescriptions

Why this matters

Peptide therapeutics are moving beyond simple weight loss to treat the root causes of metabolic syndrome, liver disease, and cardiovascular risk. Understanding this shift helps patients navigate an increasingly complex landscape of new treatments, delivery methods, and the risks associated with unregulated gray-market alternatives.
