Questions about this site

What is humanpeptides.fyi?

An adult educational index of what has been studied, published and reported about 48 peptides and related compounds, searchable by name, brand, street name or goal.

Does humanpeptides.fyi make any health claims?

No. It makes no claims of its own. Every benefit, side effect, nickname and quote is attributed to and linked to the source that published or posted it.

Does the site sell peptides?

No. The site sells nothing and has no checkout, accounts or prices. Seller pages are cited only where a claim or a name first appeared, and are labelled as sellers.

How is the strength of evidence shown?

Every entry carries one of five labels: Approved (specific use), Trial-backed, Early human, Preclinical or Unstudied, so a mouse study never reads like an approved drug.

Is anything here medical advice?

No. Nothing on the site is medical advice or dosing guidance. Talk to a licensed clinician before making any health decision; in an emergency call 911.

How much is actually known.

Every entry carries one of five evidence labels, so a promising mouse study never reads like an approved drug.

  1. Approved (specific use)

    Approved by the FDA (or a major regulator) for at least one specific use. Approval covers that use only, not the other benefits listed.

    9
  2. Trial-backed

    Larger randomized human trials exist, positive or negative, but no US approval for the uses discussed.

    5
  3. Early human

    Small, short, old, unblinded or single-group human studies.

    14
  4. Preclinical

    Mostly cell and animal studies. Human effects unknown.

    10
  5. Unstudied

    No direct studies of this product or blend. Anecdote and component data only.

Before you go in

humanpeptides.fyi is an educational index for adults. It summarizes and links to what others have published and reported about peptides and related compounds studied or used in humans. It is not medical advice and gives no dosing guidance. Many listed compounds are not approved for human use, and listing one is not a recommendation. Anecdotes are unverified. Images are AI-generated. By continuing, you agree to the Disclaimer and Terms of Use and the Privacy Notice.
