About this site

About this site.

A citation-anchored research library covering 41 peptides across 181 guides — and a plain statement of who publishes it and why that matters to you.

What this site is

Where To Buy Peptides is a research and sourcing library covering 41 research peptides. There are 181 guides here: monographs on individual compounds, mechanism deep-dives, summaries of specific trials, head-to-head comparisons, and buyer's guides on how to evaluate a supplier.

The library was originally written and published as the research section of a peptide store. It was moved to its own domain in August 2026 so that the research could be written as research — covering compounds nobody sells, discussing evidence that undercuts a product, and naming things plainly — rather than as store copy operating under commercial constraints.

What makes it different

Two things, and they are the whole editorial proposition.

Every claim links to its source. Not to another blog post summarising a study — to the study, by DOI or PubMed ID. If a number appears on this site you can click through and check it against the paper. That is a low bar that most of this category does not clear.

We report the weaknesses. BPC-157 has 36 studies and 35 of them are in animals, with roughly 80% from a single research group. Retatrutide's 24.2% comes from 338 people in Phase 2 and should be expected to regress. Sermorelin's before-and-after is a blood test, not a photograph. Those sentences are the reason to read a research library rather than a product page, and we lead with them rather than burying them.

How it makes money

Where To Buy Peptides earns revenue from purchases made through the product links in these articles — a material commercial relationship with the retailer those links point to. That is disclosed in the footer of every page and on a dedicated disclosure page, because a reader deserves to know what commercial interest sits behind what they are reading.

Our editorial policy sets out what that relationship does and does not change about what gets published — including the specific rules that exist to stop it changing anything.

What this site is not

Who writes it

Articles are published under the WTBP Research Team byline. That is a house name for the people who research, write and fact-check here, not a pseudonym for one person — and it is the name that appears in the structured data on every article, so it can be attributed accurately.

Corrections

If something here is wrong, we want to know — email hello@wheretobuypeptides.org with the page and the source that contradicts it. Substantive corrections are made to the page and noted on it.
