Therapeutic peptides
From approved medicines to research-use-only compounds — the science, the subculture, and the evidence gaps across the peptide universe.
"Peptide" now points at several different worlds — approved drugs, investigational candidates, compounded formulations, and a large research-use-only market bought by a wellness subculture. This hub holds those categories apart and labels which is which at every turn.

Peptide Purity vs Sterility
Chemical purity, sterility, and endotoxin are three independent properties measured by three different methods: purity by HPLC and mass spectrometry, sterility by USP <71>, and bacterial endotoxin by USP <85>. This explainer shows why a high purity percentage says nothing about whether a vial is sterile or pyrogen-free, and why a research-use-only powder — however pure — is not manufactured, filled, or released to the standards that make an injectable medicine sterile or lawful to inject.
What a Peptide COA Actually Tells You
A peptide certificate of analysis (COA) is a batch-specific record of laboratory tests — identity by mass spectrometry, purity by HPLC, net peptide content, water, counterion, and sometimes sterility and endotoxin. This explainer walks each line, shows why a purity percentage is not a statement of amount, sterility, or safety, and sets out what a COA cannot establish: that your vial matches the tested batch, that the document is authentic, or that the material is safe or legal to use.
Price per Milligram
In the research-use-only peptide market the same compound is sold in vials of very different sizes, so the sticker price compares nothing. This explainer shows how to reduce any listing to price per milligram, why bigger vials are almost always cheaper by it, how far the unit reaches across compounds and categories, and the one case — products sold by volume or units — where it cannot be computed at all.
What Is a Peptide?
A peptide is a short chain of amino acids — protein chemistry on a smaller scale. This explainer covers what a peptide is, where the fuzzy line with proteins falls, how peptides signal, why they are hard to turn into drugs, and how an approved peptide medicine differs from a 'research use only' chemical.
How the U.S. Research Peptide Market Works
Who sells research-use-only peptides, how the supply chain runs, what sellers actually compete on, where the demand really sits, and the legal frame that makes this a research-chemical market rather than a market in medicines.
Why Peptide Prices Vary
In the research-use-only peptide market the same compound, at the same dose, routinely varies severalfold in price between sellers. This explainer traces where that dispersion comes from and why a single average price tells a buyer almost nothing.
After the Weight Comes Off
A systematic, evidence-graded study of the second- and third-order effects of GLP-1 medicines across nineteen industries and the culture itself — grading, honestly, which consequences are real, which are exaggerated, and which are not yet proven.
From the Lab to the Feed
A South Beach Longevity intelligence report separating the peptide phenomenon into four distinct movements — a pharmaceutical revolution, a scientific field, a gray online marketplace, and a wellness subculture — and testing whether the boom is as broad as it looks.
Five things 'peptide interest' can mean — and why they're not the same
Search interest, social attention, media coverage, commercial availability, and clinical proof are five different signals. Confusing them is the most common error in the peptide conversation.
Peptide Buying Opportunities
A shareable market analysis of the research-use-only peptide retail market — pricing dispersion, seller consistency, and where value concentrates — built from a live retail-price corpus. Contains no internal cost or margin data.
Why the same peptide can cost several times more from one seller than another
In the research-use-only peptide market, price dispersion is the defining feature — not noise. Here is where it comes from, and why a headline average tells you little.
