Direct answer
True Research Labs review: 7.5/10
True Research Labs is an operating research-material store with public Horizon Analytical purity and endotoxin reports, card and Apple Pay checkout, and a substantial independent review record. Trustpilot showed 4.3/5 from 141 reviews, although recent critical reviews reported dispatch, refund, support, and product concerns. The COA library is useful but partial, and one sampled GLOW report has impossible chronology. The combined evidence supports a 7.5/10 rating.
Domain check
This review covers trueresearchlabs.com only.
Similarly named research laboratories and storefronts are separate entities unless they use this exact domain.
Domestic checkout showed $14.99 2-3 day FedEx, $29.99 expedited FedEx, and $49.99 overnight. Shipping is free over $250. The policy allows international orders where permitted, with customs risk on the customer. All sales are final.
The public library listed purity and endotoxin reports for 21 named products on 2026-08-14, while the store API listed 37 product records. PeptidePrices opened the latest Horizon Analytical reports for Selank lot TRL-9907743 (99.22%, 9.8mg; endotoxin 0.06 EU/mL), Tirzepatide lot TRL-9887337 (99.29%, 10.22mg; endotoxin <0.05 EU/mL), PT-141 lot TRL-9495443 (99.36%, 9.75mg; endotoxin <0.05 EU/mL), GLOW lot TRL-9377026 (three-component purity report; endotoxin <0.05 EU/mL), and GHK-Cu lot TRL-9372216 (99.58%, 97.5mg; endotoxin <0.05 EU/mL). The reports name Horizon, the client, lot, dates, UPLC/MS methods, measured content, purity, and a QR validation mark. Horizon has a public verification form, but the certificates do not print a separate report number and a lookup using the numeric portion of the Selank lot returned no match. The GLOW purity report also has an impossible chronology: received 2026-05-26 but analysis conducted 2026-05-12. The sampled reports do not include sterility or heavy-metals results; Horizon labels both services as coming soon.
True Research Labs has public, lot-linked Horizon purity and endotoxin reports, a live card checkout, and a substantial independent review record.
Do not treat the documentation as fully verified. The library is partial, the certificates omit Horizon's required report number, and one sampled GLOW report has impossible dates. Match the exact product, strength, and lot before relying on a report.
Verification notes
What we reviewed, with the limits of that evidence kept explicit.
01
Company and checkout
True Research Labs is a young United States research-material store. The domain was created on January 24, 2026. The site publishes 30 N Gould St Ste R in Sheridan, but that address is not confirmed as its operating location. The site does not name an owner. Checkout supports cards, Apple Pay, and bank payment with a 5% discount. Shipping is free above $250, and paid FedEx options include two-to-three-day, expedited, and overnight service. A PeptidePrices customer coupon is not available yet.
02
Public COA coverage
The public COA page showed purity and endotoxin reports for 21 named products. PeptidePrices checked report pairs for Selank, Tirzepatide, PT-141, GLOW, and GHK-Cu. The Horizon Analytical reports include lot linkage, identity, measured content, purity, and endotoxin results. Coverage remains partial. The certificates omit the report number required by Horizon's lookup form. The GLOW purity report also says the sample was analyzed before it was received.
03
True Research Labs reviews
Trustpilot listed 4.3/5 from 141 reviews. Positive samples praised fast delivery and packaging. Recent critical reviews reported unshipped orders, delayed refunds, unresponsive support, and product concerns. A Reddit thread was mixed. Customer reviews are not laboratory evidence. The evidence supports a 7.5/10 score.
