Is Nootropics Depot Legit? Reviews, Lab Testing and Returns

By , co-founder & editorial lead · Data updated

Nootropics Depot is an established supplement retailer with a substantial customer-review record and lot-specific certificates. Its Trustpilot profile showed 4.7 out of 5 from 2,782 reviews on October 15, 2026. The important testing distinction is who issues those certificates: Omnient Labs began as the retailer's in-house laboratory, and its reports have no public issuer lookup.

This guide helps readers assess customer feedback, read the supplement testing and understand shipping and return terms. Nootropics Depot is not a research-peptide vendor and is outside the PeptidePrices price index and vendor directory. PeptidePrices has no affiliate relationship with it. The findings below reflect sources checked October 15–16, 2026.

What Nootropics Depot sells, and what it does not

Nootropics Depot sells dietary supplements and nootropic ingredients as capsules, powders, tablets and blends. Its product sitemap listed 338 product URLs on October 16, 2026. Only about eight of them are peptide-related in any sense: six Glutathione products (a tripeptide) and two L-carnosine products (a dipeptide), sold as ordinary dietary supplements.

The sitemap lists no BPC-157, thymosin, GH secretagogue, GLP-1 or Semax product, and a site search for Semax returned no results. If you arrived here while comparing research-peptide vendors, this retailer is a different kind of business. Use the PeptidePrices vendor directory and the vendor vetting checklist for peptide suppliers.

The company's own tianeptine page says it does not carry that product.

Who runs it

The operating company is Centera Bioscience, which does business as Nootropics Depot. Paul Eftang is its president and chief executive. The company lists its headquarters at 8370 S Kyrene Rd, Tempe, Arizona, and a supplement logistics facility at 8380 S Kyrene Rd, which it puts at about 80,000 square feet and about 90 employees. The domain was registered on February 6, 2013. The company names its leadership, a scientific advisory board and its facilities on its own pages.

What customers say

Trustpilot. On October 15, 2026 the Trustpilot profile showed 4.7 out of 5 from 2,782 reviews: 2,461 five-star, 137 four-star, 57 three-star, 29 two-star and 98 one-star. The profile is claimed and uses a paid Trustpilot plan, and Trustpilot reported company replies to 97% of negative reviews, typically within 24 hours. PeptidePrices read the 20 newest reviews and the 20 newest one-star reviews, a 40-review window rather than all 2,782.

Recent praise describes quick delivery, clear communication and easy ordering. The critical reviews describe duplicate orders and charges, missing items, lost or misdelivered parcels, and difficulty reaching support by phone. Nineteen of the 20 one-star reviews had a company response. In one October 7 review about a duplicate order, the company replied that it had supplied a return label. A company reply shows that the company responds; it does not show that the problem was resolved.

Reddit. A Reddit search on October 16, 2026 returned the 100 newest matching posts, dated June 2 to October 15, 2026 apart from three older community pages. Fifty-one were in the company-run r/NootropicsDepot community, and the rest were mostly in r/Supplements, r/NootropicsHelp and r/NooTopics. The search covered post titles and text, not comments. Independent posters mostly praised the company's purity and testing. One August 23 poster called it the golden standard for both while doubting its claims of product innovation. Others reported side effects from specific supplements, and a few raised service points: heat exposure of a new product in summer shipping, a newsletter sign-up page that looped, and a question about four-year-old reviews showing on a brand-new product page. Posts in the company-run community are product announcements and customer discussion, so they are not independent evidence.

Product effects are individual reports, not laboratory findings.

The laboratory: Omnient Labs

Nootropics Depot links a certificate of analysis for supplement lots from its laboratory page. The certificates come from Omnient Labs, and Omnient is not independent of the retailer. In a message on the company site the CEO says he created Omnient Labs, and Omnient's own history says it began as an in-house laboratory for Nootropics Depot before it also served other supplement brands.

Omnient posts a three-page accreditation certificate that names ISO/IEC 17025 accreditation number 113861, certificate L25-392, issued May 19, 2025 and expiring May 31, 2027. Its scope includes FTIR identity, capsule mass and residual solvents. PeptidePrices could not confirm the accreditation in the accreditor's own directory, so the status rests on the posted document. The company also posts a cGMP certificate for its logistics facility; that is a company-supplied document PeptidePrices did not verify with the issuer.

PeptidePrices retained 155 Omnient certificates dated November 2023 to September 2026. What they show:

  • Identity and metals. All 155 print a heavy-metals result. 149 report FTIR identity, two report NMR with polarimetry, and four Glutathione capsule sheets use specific rotation.
  • Quantities. 145 print a quantitative assay, usually per capsule, tablet or serving. Water activity appears on 153.
  • Glutathione. Ten of the certificates cover Glutathione, from March 4, 2024 to May 12, 2026. The 500 mg products measured between 515 mg and 517.7 mg per capsule.
  • No purity percentage. A 98% FTIR library match is an identity similarity score, not 98% chemical purity. Sterile-product tests such as endotoxin do not appear, and they would not normally apply to an oral supplement.
  • Paperwork conflicts. Three powder reports print package sizes that disagree with their own jar-fill weights: Cognizin ND-25-370 and Alpha-GPC 99% ND-25-788 print 30 g against 60 g, and Triacetyluridine ND-25-918 prints 25 g against 50 g.

Omnient offers no public lookup for individual reports, so a reader cannot confirm a certificate with the laboratory. PeptidePrices found no independent third-party test of Nootropics Depot's finished products, so the results above are the company's own laboratory describing the company's own lots.

Shipping, payment, returns and coupons

At a Massachusetts checkout on October 15, 2026, FedEx 2-Day was $10.50, USPS Priority Mail (3 to 5 days) was $10.60 and FedEx Home Delivery (3 to 7 days) was $25.42. Free U.S. shipping applies over $50, and standard international mail is free over $200. Orders placed before 4 p.m. Arizona time usually dispatch the same day. The checkout showed Visa, Mastercard, American Express, PayPal, PayLater and Google Pay, and the policy also lists Venmo.

Returns are limited. The company accepts unopened, sealed products within 30 days of delivery, with return postage paid by the buyer. Opened or used products and expedited-shipping fees are excluded, and replacement of a lost parcel is at the company's discretion.

Nootropics Depot says it no longer offers routine discount codes and that third-party codes are invalid. Its affiliate program excludes coupon and promotional-offer sites and prohibits non-exclusive coupon codes. For that reason PeptidePrices shows no coupon for this retailer.

Regulatory history: the 2017–2021 drug catalog

  • Case. A plea agreement for Centera Bioscience, doing business as Nootropics Depot, was filed on August 16, 2023, in the U.S. District Court for the District of New Hampshire (case 1:23-cr-00069). The company agreed to plead guilty to an information charging introduction of a misbranded drug into interstate commerce, a violation of 21 U.S.C. § 331(a). The agreement notes this is a strict-liability offense.
  • Conduct. The agreement says that between April 2017 and December 2021 the company and its CEO sold several drugs, including tianeptine, phenibut, adrafinil and racetam drugs. It names piracetam, aniracetam, coluracetam and phenylpiracetam. It says they were sold as nootropics intended to affect the structure or function of the body, that the labeling lacked adequate directions for use, and that they were marketed through Facebook, Google and a Reddit forum.
  • Penalty. The agreement provides for a $2.4 million forfeiture money judgment plus drugs seized by customs and FDA investigators. According to the Justice Department's releases, as hosted by the FDA, the company and the CEO pleaded guilty on October 30, 2023, and were sentenced on February 5, 2024: three years of probation for the company and one year for the CEO.

Read the primary documents yourself: the plea agreement, the plea release and the sentencing release.

The case concerned drugs sold from April 2017 through December 2021. None of the named drugs appeared in the October 16, 2026 product sitemap. Keep that historical enforcement record separate from the current supplement lot results discussed above.

What to check before ordering

Read recent customer reviews for the issues that matter to your order: delivery, missing items, duplicate charges and access to support. The 4.7 Trustpilot average summarizes thousands of reviews; the 40-review reading window above identifies specific reported service issues. Company responses and resolved complaints are separate evidence.

For testing, locate the certificate for the exact product and lot. Read identity, quantitative assay and heavy-metal results separately, and distinguish Omnient's relationship with the retailer from a laboratory independent of it. An FTIR library-match percentage describes spectral similarity, not chemical purity. The three package-size conflicts above are reasons to compare the report with the product label.

Check the unopened-only return rule before purchasing. The published lot reports and customer record provide useful evidence about the retailer; they do not establish how a supplement will affect an individual.
