What to ask when you call

Do you prescribe peptide therapy? Not every listing here will.
Where does the product come from? A licensed compounding pharmacy — ask which.
Is it FDA-approved for this use? A good clinic says plainly when something is off-label or unapproved.
What monitoring is included? Baseline labs and follow-up, especially for anything affecting blood glucose or IGF-1.
What is the total cost? Consultation, medication, labs, and follow-up — not just the headline price.

Listings are informational, not endorsements. We do not verify credentials, outcomes, or pricing, and inclusion implies no recommendation. Confirm licensure with the Illinois medical board. Corrections and removals are free.
