Peptides and regenerative medicine are everywhere online — most of it unregulated and unsupervised. RegenTherapy MD offers the opposite: a physician-directed, honest library of what these therapies are, what the evidence and FDA status actually say, and how a medically supervised program works.
Quick answer: This library organizes physician-directed peptide and regenerative therapies by goal — weight loss, recovery, anti-aging, and hormone optimization — with honest profiles of individual therapies and side-by-side comparisons. Every therapy here is consultation-gated and medically supervised by Dr. Hootan Zandifar.
Why physician-directed matters
The internet is full of peptide vendors selling unregulated 'research chemicals' with DIY dosing. That carries real quality and legal risk. Everything here is different: evaluated, sourced responsibly, and monitored by a physician — with honest guidance on what is and isn't FDA-approved.

Frequently asked questions
Are peptides safe?
Under physician supervision with appropriate evaluation and monitoring — yes. Unsupervised online products are a different, riskier story.

Some (like semaglutide and tirzepatide) are approved; others are not, and we tell you honestly on each page.
Do I need a prescription?
The therapies we use are physician-directed and consultation-gated.
