Questions about Peptira LLC
Answers based on the published evidence—not a vendor endorsement.
Is Peptira LLC legit?
TitrateLab does not rank or recommend vendors; it reports what independent labs measured. Peptira LLC shows high measured purity (99.3% mean across 328 positive purity measurements). Dose accuracy is mixed and recent underfills are uncommon: in the last 12 months 107 of 230 dose results were on target, 4 under label and 119 over; all time 121 of 258 on target, 7 under and 130 over. These results describe tested batches, not every product or shipment.
What is Peptira LLC's average purity?
99.3% mean measured purity across 328 positive third-party lab results; 326 were at or above 90% and 2 were below.
How many Peptira LLC lab certificates has TitrateLab tracked?
361 third-party certificates from 2025-06-25 to 2026-09-14, covering 68 compounds.
How accurate are Peptira LLC's doses?
Dose accuracy is mixed and recent underfills are uncommon: in the last 12 months 107 of 230 dose results were on target, 4 under label and 119 over; all time 121 of 258 on target, 7 under and 130 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 Peptira LLC failed an endotoxin test?
Endotoxin was reported on 41 of 361 counted records (11.4%). No failures were recorded in those 41.
Sources, definitions & limits
361 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 2026-03-19 through 2026-09-19, 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 41 records have a classifiable result. Community sentiment describes reviews, not laboratory measurements or independently verified purchases. Results are not certification, medical advice or endorsement.
Missing measurements stay missing. Membership unlocks access, not additional testing.
