How the fills compare
21 fill tests · All timeMeasured against the printed amount. Finnrick quantities are excluded.
Beyond the purity average
124 positive testsMean 99.6% · Median 99.8%. The 90% grouping is not a safety threshold.
Test coverage & missing results
5 records have no usable purity outcome. 108 do not have a comparable fill test. 125 lack a classified endotoxin result. A classified pass does not mean no endotoxin was detected.

Questions about DSP
Answers based on the published evidence—not a vendor endorsement.
Is DSP legit?
TitrateLab does not rank or recommend vendors; it reports what independent labs measured. DSP shows high measured purity (99.6% mean across 124 positive purity measurements). Dose accuracy is mixed: in the last 12 months 4 of 17 dose results were on target, 1 under label and 12 over; all time 6 of 21 on target, 3 under and 12 over. These results describe tested batches, not every product or shipment.
What is DSP's average purity?
99.6% mean measured purity across 124 positive third-party lab results; 124 were at or above 90% and 0 were below.
How many DSP lab certificates has TitrateLab tracked?
129 third-party certificates from 2025-07-16 to 2026-09-11, covering 33 compounds.
How accurate are DSP's doses?
Dose accuracy is mixed: in the last 12 months 4 of 17 dose results were on target, 1 under label and 12 over; all time 6 of 21 on target, 3 under and 12 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 DSP failed an endotoxin test?
Endotoxin was reported on 4 of 129 counted records (3.1%). No failures were recorded in those 4. Coverage is too limited for a vendor-wide conclusion.
Sources, definitions & limits
129 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 2026-04-02 through 2026-10-02, 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 4 records have a classifiable result. Community sentiment describes reviews, not laboratory measurements or independently verified purchases. Results are not certification, medical advice or endorsement.
