Questions about ERP

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

Is ERP legit?

TitrateLab does not rank or recommend vendors; it reports what independent labs measured. ERP shows high measured purity (99.4% mean across 128 positive purity measurements; 4 identity failures reported separately). Dose accuracy is mixed and no recent result was under label: in the last 12 months 5 of 8 dose results were on target, 0 under label and 3 over; all time 5 of 8 on target, 0 under and 3 over. These results describe tested batches, not every product or shipment.

What is ERP's average purity?

99.4% mean measured purity across 128 positive third-party lab results; 126 were at or above 90% and 2 were below. In 4 additional tests, the labeled compound was not detected.

How many ERP lab certificates has TitrateLab tracked?

141 third-party certificates from 2025-09-30 to 2026-09-09, covering 16 compounds.

How accurate are ERP's doses?

Dose accuracy is mixed and no recent result was under label: in the last 12 months 5 of 8 dose results were on target, 0 under label and 3 over; all time 5 of 8 on target, 0 under and 3 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 ERP failed an endotoxin test?

Endotoxin was reported on 34 of 141 counted records (24.1%). No failures were recorded in those 34.

Sources, definitions & limits

141 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 2026-03-16 through 2026-09-16, 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 34 records have a classifiable result. Community sentiment describes reviews, not laboratory measurements or independently verified purchases. Results are not certification, medical advice or endorsement.
