Read document reviewPEPTIDE NEWS · SUPPLY-CHAIN WATCH
FDA updated its GLP-1 import alert. One COA is not the whole quality system.
The September 21 revision describes border detention, a Green List, and the evidence FDA expects beyond a single lot certificate—including validated methods, specifications, stability, and manufacturing records.
THE NUMBER IS NOT THE WHOLE STORY
“99% pure” answers one question. Not seven.
A polished certificate can still leave the most important questions unanswered. Compound IQ helps readers separate reported results from assumptions.
Purity is not identity
A strong purity result does not independently confirm that the material is the compound named on the label.
Label is not quantity
A labeled amount is a claim. Look for a measured content result before treating it as verified.
One lot is not every lot
A report applies to the tested sample and lot. It should not be stretched into a promise about future inventory.

“Not detected” is not proof of zero.
Learn how the reported limit changes what a lab result can establish, and which questions to ask before interpreting a contaminant screen.
THE COMPOUND IQ FRAMEWORK
Seven checks. Fewer assumptions.
Use the checklist as a repeatable first pass before accepting a supplier claim, ranking, or recommendation.
Identity
Does the report confirm what the tested compound actually is?
Purity
Which method produced the percentage, and is the chromatogram included?
Quantity
Was net content measured, or is the report repeating the label claim?
Lot match
Does the tested lot match the product and supplier record being reviewed?
Sterility
When sterility is claimed, are the method, specification, and result reported?
Endotoxin
Is there a quantitative result with units, method, and stated limit?
Contaminants
Which metals or other analytes were tested, and at what reporting limits?
INDEPENDENCE BEFORE INCOME
The review stays useful only if the limits stay visible.
Compound IQ may earn commissions through clearly identified partner links. That relationship is disclosed near each relevant link, and it will never turn missing evidence into a passing score.
- 01Verify the source
Open the laboratory verification record, not only the supplier screenshot.
- 02Match the lot
Connect the report to the specific product and lot being discussed.
- 03Separate fact from assumption
Report only the methods, analytes, and results actually present.
- 04Disclose the relationship
State commissions and document-review limitations where readers will see them.

STRAIGHT ANSWERS
What this framework can—and cannot—do.
Does a passing COA prove a compound is safe?
No. A COA speaks to the tested sample, methods, and analytes. It does not establish every possible contaminant, ongoing supplier practices, future lots, or suitability for any use.
Is Compound IQ providing medical advice?
No. Compound IQ provides research education and document-analysis tools. We do not diagnose, prescribe, recommend dosing, or establish suitability for human use.
Do you independently test every supplier?
Not currently. Reviews based on supplier or public documents are labeled as document reviews. We state what the evidence establishes and what remains untested or unknown.
Will affiliate partnerships affect a score?
No. Any commission relationship will be disclosed clearly near the relevant recommendation. A partnership does not replace evidence or change the review framework.
