About this site
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.
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.
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.
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.
