Questions about CRC

Answers based on the published evidence—not a vendor endorsement.

Is CRC legit?

TitrateLab does not rank or recommend vendors; it reports what independent labs measured. CRC shows high measured purity (99.7% mean across 77 positive purity measurements). Dose accuracy is mixed and recent underfills are uncommon: in the last 12 months 33 of 66 dose results were on target, 2 under label and 31 over; all time 33 of 66 on target, 2 under and 31 over. These results describe tested batches, not every product or shipment.

What is CRC's average purity?

99.7% mean measured purity across 77 positive third-party lab results; 77 were at or above 90% and 0 were below.

How many CRC lab certificates has TitrateLab tracked?

90 third-party certificates from 2026-03-27 to 2026-09-29, covering 40 compounds.

How accurate are CRC's doses?

Dose accuracy is mixed and recent underfills are uncommon: in the last 12 months 33 of 66 dose results were on target, 2 under label and 31 over; all time 33 of 66 on target, 2 under and 31 over. A dose result compares the measured amount with the amount printed on the label: under is more than 10% below, over is more than 10% above, on target is everything in between. Finnrick results are excluded because that lab measures against the vendor's batch claim. Missing values are never counted as passes.

Has CRC failed an endotoxin test?

Endotoxin was reported on 25 of 90 counted records (27.8%). No failures were recorded in those 25.

Sources, definitions & limits

90 published records are attributed to this vendor. The current certificate index excludes 0 repeated records using file hashes and supported lab verification links. Missing identity keys can leave repeated certificates. Recorded name groups can include variants, mixtures and unclassified names.

Evidence dates describe the tested samples, not when the vendor was founded, current stock, or a performance trend. Purity uses positive measurements only. Exact-zero purity is a not-detected identity outcome, not proof of an empty vial. A zero measured amount requires an explicit numeric amount result; missing amounts are not zero.

Underfills and overfills here exceed 15% in either direction against the printed amount. Vendor batch claims are not used; Finnrick quantity comparisons are excluded. Recent outcomes cover 2026-04-03 through 2026-10-03, inclusive. The older published ±10% partition may appear in the existing FAQ and is a different, explicitly labelled threshold. Missing tests are not passing results.

Endotoxin failures, borderline outcomes and passes use the recorded lab verdict. A pass is not proof of no endotoxin. Only 25 records have a classifiable result. Community sentiment describes reviews, not laboratory measurements or independently verified purchases. Results are not certification, medical advice or endorsement.
