◆ GOOD TO KNOW

Frequently asked questions

Who is Center for Peptide Research
CPR is a clinician-guided platform connecting patients with licensed providers and a 503A compounding pharmacy. We offer GLP-1 weight loss therapy, regenerative and longevity peptides, capsules, and over-the-counter wellness products — delivered to your door, 100% online.
Products marked “Rx Required” are dispensed only after a licensed provider reviews your medical intake and confirms the treatment is appropriate. Our over-the-counter products do not require a prescription.
Compounded medications are prepared for specific patient needs and have not been reviewed or approved by the FDA for safety or effectiveness. All formulations undergo third-party analytical testing to confirm potency as labeled, and our pharmacy operates under applicable state and federal regulations.
Once your intake is reviewed and approved, your prescription is filled and shipped in discreet packaging, typically arriving within 2–3 business days.
If a provider determines a prescription product isn’t right for you, you won’t be charged for that medication. Our team will notify you and walk you through any alternative options.
Providers often recommend at least three months for optimal results, and our multi-month packages are more cost-effective over time. You can choose your preferred option at checkout.
