Common questions
What we cover, how we check it and where our role ends.
Is Designing Longevity a medical provider?
No. We are an informational resource only. We do not employ doctors, write prescriptions, or offer telemedicine services. Our goal is to provide research-backed education so you can have better conversations with your own healthcare team.
Do you tell me what dose to take?
Never. Dosing is highly individual and depends on your medical history, blood work, and tolerance. We may discuss standard protocols found in clinical literature, but this is for reference only and not a recommendation for you.
What do provider comparisons tell me?
They compare dated public prices, program terms and documented checks. They do not determine which treatment is suitable for you or guarantee clinical quality. Each page explains its review scope and gaps. We may earn a fee from links marked "We earn a fee". Our policy is to score providers using the published rubric and to disclose paid relationships beside the relevant links. Providers can be included without paying us. We do not accept payment for a higher ranking or per-prescription compensation.
Do you cover unapproved peptides?
We discuss emerging compounds and distinguish their research evidence from regulatory approval. Covering a compound does not mean we recommend using it. Our peptide guides explain evidence gaps and known risks.
