Test coverage & missing results
54 records have no usable purity outcome. 223 do not have a comparable fill test. 635 lack a classified endotoxin result. A classified pass does not mean no endotoxin was detected.

Questions about Simple Peptide
Answers based on the published evidence—not a vendor endorsement.
Is Simple Peptide legit?
TitrateLab does not rank or recommend vendors; it reports what independent labs measured. Simple Peptide shows high measured purity (99.4% mean across 597 positive purity measurements; 1 identity failure reported separately). Dose accuracy is mixed and recent underfills are uncommon: in the last 12 months 160 of 322 dose results were on target, 6 under label and 156 over; all time 217 of 429 on target, 15 under and 197 over. These results describe tested batches, not every product or shipment.
What is Simple Peptide's average purity?
99.4% mean measured purity across 597 positive third-party lab results; 595 were at or above 90% and 2 were below. In 1 additional test, the labeled compound was not detected.
How many Simple Peptide lab certificates has TitrateLab tracked?
652 third-party certificates from 2025-01-01 to 2026-09-05, covering 101 compounds.
How accurate are Simple Peptide's doses?
Dose accuracy is mixed and recent underfills are uncommon: in the last 12 months 160 of 322 dose results were on target, 6 under label and 156 over; all time 217 of 429 on target, 15 under and 197 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 Simple Peptide failed an endotoxin test?
Endotoxin was reported on 17 of 652 counted records (2.6%). No failures were recorded in those 17. Coverage is too limited for a vendor-wide conclusion.
Sources, definitions & limits
652 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 2026-03-17 through 2026-09-17, 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 17 records have a classifiable result. Community sentiment describes reviews, not laboratory measurements or independently verified purchases. Results are not certification, medical advice or endorsement.
