Compound IQ has an affiliate relationship with ZC Labs and may earn a commission from the clearly identified partner link on this page. That relationship does not change the document score or the limitations we report. We did not purchase or independently test this lot; this is a review of the supplier's public record and linked laboratory information.

The reported net content is 1.28 mg, or about 8.5%, above the 15 mg product description. The public record reports the measurement but does not show a numerical content acceptance range or a separate content pass/fail decision.
WHAT THE HEADLINE DOES NOT SAY
Four limits that belong beside the score.
Three evidence categories are absent
The public record reviewed does not report sterility, quantitative endotoxin, heavy metals, residual solvents, or another broader contaminant panel.
The result applies to one submitted lot
The 99.89% purity and 16.28 mg content results apply to lot ZC-RT15-101. They should not be extended to another lot or to current inventory without a lot match.
A public record is not chain-of-custody proof
The supplier and laboratory fields support document traceability, but the public record does not establish that the laboratory independently selected the sample from saleable inventory.
Analytical coverage is not suitability
Identity, purity, and content results do not establish safety, efficacy, regulatory approval, or suitability for human or veterinary use.
COMPOUND IQ VERDICT
Useful lot-specific core data—not a complete quality profile.
This public record earns 4/7 document coverage for identity, purity, measured content, and lot traceability. Its strongest feature is the alignment of a named lot with quantitative purity and content results. Its central weakness is the absence of sterility, endotoxin, and contaminant panels, which keeps a strong purity headline from becoming a complete quality claim.
