TitrateLab has 7 lab test records for Helixbridge, tested from to , covering 3 product names. Median measured purity is 99.7% across 7 purity tests, and none was below 90%. In the last 6 months, 2 fill tests compared the measured amount with the label: 0 were more than 15% under and 1 was more than 15% over. None of the 3 classified endotoxin tests failed. Lab results describe the batches that were tested, not every product or order.

TitrateLab does not rank or recommend vendors; it reports what independent labs measured. Helixbridge shows high measured purity (99.7% mean across 7 positive purity measurements). Dose accuracy is mixed and no recent result was under label: in the last 12 months 1 of 2 dose results were on target, 0 under label and 1 over; all time 1 of 2 on target, 0 under and 1 over. These results describe tested batches, not every product or shipment.
99.7% mean measured purity across 7 positive third-party lab results; 7 were at or above 90% and 0 were below.
7 third-party certificates from 2026-07-01 to 2026-09-07, covering 3 compounds.
Dose accuracy is mixed and no recent result was under label: in the last 12 months 1 of 2 dose results were on target, 0 under label and 1 over; all time 1 of 2 on target, 0 under and 1 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.
Endotoxin was reported on 3 of 7 counted records (42.9%). No failures were recorded in those 3. Coverage is too limited for a vendor-wide conclusion.
Names on reports; vendor role unverified. A test record is not necessarily a unique certificate.
The reports describe the batches that were tested, not an untested vial or an offer from this vendor.
7 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 2026-04-10 through 2026-10-10, 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 3 records have a classifiable result. Community sentiment describes reviews, not laboratory measurements or independently verified purchases. Results are not certification, medical advice or endorsement.
