Chapter one · A plain-language care guide
Learn what a peptide is, how to check a claim about aging, and what to ask before choosing care.
Make my starting sheetYou can be curious without being ready to choose.
What do I
want to ask?
Medicine name.
Studies in people.
The full cost.
A little space to think.
The short version
Small parts called amino acids join in a short chain to make a peptide. Proteins are made from these same parts.
The name of the medicine is still unclear if an offer says only “peptide”. Ask for its name, what it is meant to do, and what studies in people show.
Make aging well specific
Insulin is one example of a peptide.
For a broad goal like aging well, ask about a specific change: what do I hope to improve, and how would we measure it?
Ask for research in people with that same goal. Ask what remains unknown. An answer can be useful even when it leaves you undecided.
Check the kind of product
Check which medicine an offer names and what it promises.
Ready-made medicine
Semaglutide (Ozempic, Wegovy) holds FDA approval for specific medical uses, as of September 2026.
Ask which health problem this medicine is intended to treat. For a claim about aging, ask for studies in people with that goal.
For one patient’s need
Compounding is making a medicine for one patient’s particular need; a doctor or pharmacist prepares it.
Compounded medicines had no FDA approval as of September 2026. Before sale, the FDA does not check a compounded medicine’s safety, how well it works, or how well it is made.
As of September 2026, US law allows compounding only when the legal requirements are met.
Research label
FDA advice reviewed in September 2026 warns against semaglutide and tirzepatide offered for human use under a “for research” label. The FDA says their quality is unknown, and people may be harmed by using them.
A “for research” label does not make a product suitable for medical care.
Write down the medicine’s name and ask a health professional about it.
Epitalon and MOTS-c are names of peptides sold online.
Neither epitalon nor MOTS-c had a US FDA approval as of September 2026.
Lack of FDA approval alone does not prove that a substance causes harm.
If an offer names either peptide for aging, ask what change it promises and what studies in people support that claim.
Human growth hormone is the name of a peptide medicine also called somatropin.
If it is offered for aging, this rule matters:
As of September 2026, distributing human growth hormone for anti-aging is a federal crime.
