Common Questions

Quick answers to the questions we hear most.

Where can I use Peptides.io?

Peptides.io is a free site for people in the United States. The providers we feature are licensed, and together they cover all 50 states.

What is available can change from state to state, because each state has its own rules.

When you pick a provider, their own sign-up checks if you qualify in your state before anything else happens.

Does Peptides.io sell peptides or take payments?

No. We are a free site that helps you learn and compare. We do not sell, prescribe, mix, or ship any medicine. We never take your payment.

Everything — checking if you qualify, ID checks, the prescription, and shipping — is done by the licensed providers we link to, not by us.

How does Peptides.io make money?

When you click over to a partner provider and sign up, we may earn a small commission. That does not change our ratings or what we suggest. See our Advertiser Disclosure to learn more.

How does Peptides.io rate providers?

We score them on a few things: clear pricing, which states they cover, real doctor oversight, good customer service, and what they offer. No one can pay for a better score. See our Editorial Policy for the full method.

Does Peptides.io give medical advice?

No. Everything here is for learning only. It is not medical advice, and it cannot diagnose or treat you. Always talk to a licensed doctor before you start any peptide therapy.

Who writes the content on Peptides.io?

Our writing team does — including Kelly Miller (health writer and educator) and Sarah Chen (health and wellness editor). Every article is checked for accuracy before it goes up. See Our Team to learn more.
