Understand peptides.
Follow the evidence.
A clearer place to explore the research, understand testing, and ask better questions. Start with the basics. Keep the sources close.

Evidence about a compound and testing of a sample answer different questions. We help you keep them separate.
Start with a question.
No jargon required. Choose the part you want to understand first.
What am I looking at?
Learn the language, find a compound profile, and separate a proposed mechanism from a measured result.
Understand the basics Learning path 02What does this report prove?
Read a certificate of analysis, check the sample identifiers, and see what each test can and cannot tell you.
Learn to read testing Learning path 03How strong is the evidence?
Tell a study registration from a result, spot the source type, and read an announcement without skipping the caveats.
Build your research skillsA certificate is a starting point.
Not the whole story.
One percentage cannot answer every quality question. Learn how to read the methods, match the report to the sample, and identify the missing information.
Explore testing & COAsFive separate questions
- 01Identity
What supports the claimed compound? - 02Chromatographic purity
What proportion of detected peak area is assigned? - 03Net peptide content
How much was measured in the sample? - 04Endotoxin
What did this assay detect, at what limit? - 05Microbial screening
Which targets were tested, using which method?
These tests do not, by themselves, establish sterility or suitability for human use.
Headlines worth opening.
Sources worth checking.
Recent agency developments and clearly dated methods explainers. No shortcut from a headline to a product claim.
Peptides reached an FDA agenda. That is not an approval.
What a July 2026 FDA agenda can tell you about peptide compounding discussions, and why it cannot establish approval.

Two August 2026 FDA letters show why a research-use disclaimer cannot be read apart from the surrounding claims.

Why matching the quantity, method, sample, and uncertainty matters more than comparing two purity percentages.
