# About Peptide Medicine NY

> About Peptide Medicine NY: an independent editorial digest of published research on GHK-Cu, PT-141, retatrutide, and semaglutide. Not a clinic, not a pharmacy, not a store.

An independent literature digest — not a clinic, not a pharmacy, not a sales page.

## What this site is

Peptide Medicine NY is an independent editorial digest of published research on four peptides — GHK-Cu, PT-141, retatrutide, and semaglutide. It exists because these four keep coming up in the same conversation: a patient reads something online, brings it to a clinician, and the clinician needs a straight, sourced answer faster than a literature search allows. This site is that answer, written down.

It is not a clinic. It does not diagnose, prescribe, dispense, or sell any of the compounds it covers. It does not recommend a dose for anyone, under any circumstance — that decision belongs to a licensed clinician working with an actual patient, not a website. Every factual claim on this site traces to a specific study, trial, or regulatory document, listed by number on the [references page](/references). Where a claim is community-reported rather than clinically studied, it is labeled **anecdotal, not clinical evidence**, plainly, every time.

## How to read this site

Each compound page follows the same arc: what it is, structurally; how it works, mechanistically; what the actual trial or study data shows, with citations; what people report experiencing outside of clinical settings, labeled as anecdotal; and what the literature specifically flags as a safety concern, also cited. The [comparison page](/compare) puts all four side by side on the dimensions that actually distinguish them — mechanism, evidence depth, regulatory status, and biggest caution.

A study result and a forum post are not the same kind of evidence, and this site never blends them without saying which is which. A Phase 2 trial and an FDA-approved label are not the same kind of evidence either, and the difference matters more than most marketing acknowledges. Reading in that order — mechanism, then evidence, then reported experience, then caution — is the fastest way to actually understand one of these compounds rather than just absorb someone else's conclusion about it.

## Editorial stance

This site takes no position on whether any individual should use any of these compounds. That is not editorial neutrality for its own sake — it is a recognition that the right answer depends on a specific person's medical history, which a website cannot know and should not guess at. What this site will do is state plainly when evidence is strong, when it is thin, when it is Phase 2 instead of Phase 3, and when a claim is coming from a forum instead of a trial.

None of the compounds discussed here are sold, linked to a vendor, or promoted in any way on this site. No competitor brand names are referenced. This is a reading desk, not a storefront — and it stays that way on every page.
