| +18 | Public lot-level COAs on product pages: sampled current product pages for L-theanine, Bacopa 24%, Cognance, Magtein, Cistanche, Berberine Phytosome, and Lion's Mane; each displayed lot-number COA links or a COA/lab-testing section. Rubric range is +15 to +20 for a public COA portal in Quality. Applied +18 rather than +20 because this was a broad sample, not a verified all-SKU audit. 1, 8, 9, 10, 12, 13, 14, 38 Current product pages crawled 2026; 100% weight. · full weight |
| +10 | ISO/IEC 17025 testing capability: Omnient Labs states it is ISO/IEC 17025:2017 accredited, and its certificate identifies Chemical Testing accreditation at 8370 S. Kyrene Rd., Tempe, AZ. Rubric range is +8 to +12 for ISO 17025 testing; applied +10 because the lab is accredited and technically relevant, but it is owner-linked rather than a fully arm's-length consumer certifier. 2, 3, 39 Current accreditation evidence includes a 2024 update; 100% weight. · full weight |
| +8 | cGMP manufacturing certification and facility-control signal: Nootropics Depot discloses Supplement Logistics as its dedicated manufacturing company in Tempe, and Supplement Logistics publishes a cGMP certificate page. Applied +8 as a facility-quality positive, below the NSF/USP facility certification range because no NSF/USP registration for Nootropics Depot or Supplement Logistics was verified. 1, 4, 5, 20 Current official pages; 100% weight. · full weight |
| +8 | Third-party and partner-lab testing disclosed: Nootropics Depot says Omnient coordinates finished-lot COAs and works with partner labs; sampled COAs list analytical methods and pass/fail results. Rubric range is +8 to +12 for third-party independent testing disclosed; applied +8 because testing is strongly documented, but the primary lab is within the founder-controlled ecosystem. 5, 6, 7, 16, 26 Current pages and recent COAs; 100% weight. · full weight |
| +4 | Heavy-metals testing disclosed: official support materials say incoming batches are tested for dangerous and toxic compounds such as heavy metals; sampled COAs include heavy-metal result lines. Rubric range is +3 to +6; applied +4 because the practice is visible across sampled COAs, though not independently audited across the whole catalog in this review. 6, 7, 16, 40 Current/recent COAs; 100% weight. · full weight |
| +4 | Microbiological and contaminant testing disclosed: Omnient advertises microbial, pesticide, residual-solvent, heavy-metal, identity, and assay testing services, and Nootropics Depot states finished-lot COAs consolidate testing. Rubric range is +3 to +6; applied +4 because scope is well described but not all raw data were audited. 3, 5, 16 Current pages; 100% weight. · full weight |
| +5 | Ingredient identity and potency testing: Nootropics Depot states each incoming batch is tested for identity and purity, Omnient describes identity and assay testing with advanced instrumentation, and sampled COAs show assay/identity-style methods. Rubric range is +3 to +6; applied +5 for unusually detailed testing infrastructure relative to typical supplement brands. 3, 6, 7, 40 Current/recent evidence; 100% weight. · full weight |
| +5 | In-house/sister analytical lab with professional staff and instrumentation: Omnient reports 17 full-time laboratory scientists and quality-control personnel and describes UPLC-QDa, HPTLC, Agilent, Thermo, Mettler Toledo, Anton Paar, and other instruments. Rubric range is +3 to +6; applied +5 because the staffing/instrumentation detail is stronger than normal in the supplement market. 2, 3 Current official pages; 100% weight. · full weight |
| −5 | Independent quality-testing caveat: ConsumerLab's public brand report says 2 Nootropics Depot products were tested, with 1 Approved and 1 Not Approved. This is not enough to generalize across the catalog, but it is a direct independent quality signal. Applied a limited -5 penalty, equivalent to 25% of a -20 quality-failure pattern penalty, because the sample is only 2 products and details are behind ConsumerLab's member wall. 15 ConsumerLab report current in 2026; 100% weight. · full weight |

| +13 | Effective dosing pattern in sampled products: 8 of 10 sampled products appeared plausibly or directly clinically dosed or strongly standardized: L-theanine 200 mg, Bacopa 300 mg at 24% bacosides, Magtein 2001 mg/144 mg elemental magnesium, Tongkat Ali 10% eurycomanone, Cistanche standardized to echinacoside/acetoside, Berberine Phytosome 550 mg, Alpha-GPC 300 mg, and Caffeine + L-theanine ratio options. Rubric range is +10 to +15 for effective doses in a majority of the line; applied +13 because sampled evidence is strong but not a complete catalog audit. 8, 9, 11, 12, 13, 14, 27, 28, 29, 30, 41 Current labels plus clinical literature; 100% weight. · full weight |
| +10 | Bioavailability and delivery technologies: sampled line includes Magtein magnesium L-threonate, Berbevis Berberine Phytosome, Cognance's hydrolysis/ebelin-lactone approach, and Lion's Mane dual extract. Rubric range is +8 to +12; applied +10 because this is a repeated formulation theme across sampled specialty products. 10, 12, 14, 30 Current product pages; 100% weight. · full weight |
| +6 | Branded or premium ingredients: sampled products include Magtein and Berbevis, and Nootropics Depot also sells branded Bacognize Bacopa. Rubric range is +5 to +8; applied +6 because branded ingredients are present but not universal across the broad catalog. 12, 14, 42 Current product pages; 100% weight. · full weight |
| +7 | Proprietary formulation/research innovation: Cognance is presented as a patented Bacopa-derived ebelin-lactone extract, and Nootropics Depot explains the extraction/hydrolysis rationale. Rubric range is +7 to +10; applied +7 because it is an identifiable formulation innovation, but no finished-product human clinical trial on Cognance was found in this review. 10, 43 Current product pages; 100% weight. · full weight |
| +6 | Full dose disclosure/no proprietary blends in sampled products: sampled product pages disclose per-serving actives such as 200 mg L-theanine, 300 mg Bacopa, 100 mg Cognance, 2001 mg Magtein, 700 mg Cistanche, and 550 mg Berberine Phytosome. Rubric range is +5 to +7; applied +6 based on 10/10 sampled products, with no claim of a full catalog audit. 8, 9, 10, 12, 13, 14 Current product pages; 100% weight. · full weight |
| +5 | Synergistic combinations and evidence-grounded ratios: Caffeine + L-theanine product options mirror commonly studied caffeine/theanine pairings, and research supports the 200 mg L-theanine + caffeine concept for attention. Rubric range is +5 to +8; applied +5 because this is strong for that product but only one sampled combination. 28, 44 Current label plus clinical literature; 100% weight. · full weight |
| −5 | External testing caveat for formulation/potency: ConsumerLab publicly reports that 1 of 2 tested Nootropics Depot products was Not Approved. Using pattern detection, 1/2 would be 50%, but because the public page does not show the underlying reason and the sample is only two products, applied only 25% of a -20 underdosing/failed-quality pattern penalty = -5. 15 ConsumerLab report current in 2026; 100% weight. · full weight |

| +23 | Public COA access: sampled current product pages expose lot-specific COA lists, instructing shoppers to match the lot number on the bottle. Rubric range is +20 to +25 for public COA portal; applied +23 because access is unusually strong, but this review did not verify every SKU and every historical lot. 8, 9, 10, 12, 13, 14, 38 Current product pages; 100% weight. · full weight |
| +15 | Regular test-result publication: multiple sampled product pages publish many lot IDs, and COAs appear as downloadable PDFs.

| +9 | Testing labs and methodology disclosed: Nootropics Depot names Omnient Labs and partner labs, while Omnient provides accreditation and capability details. Rubric range is +8 to +12 for third-party testing disclosed; applied +9 because the lab and methods are disclosed, but the primary lab is within the founder-controlled ecosystem. 2, 3, 5 Current official pages; 100% weight. · full weight |
| +8 | Ownership/manufacturing structure disclosed: official pages say founder Paul built Supplement Logistics and Omnient Labs, and a company representative on Reddit identifies Nootropics Depot and Natrium Health as sister companies under Centera Bioscience. Rubric range is +8 to +12 for ownership disclosure; applied +8 because the structure is mostly findable, but the official retail site could state the Centera parent relationship more plainly. 1, 25 Current/2025 discussion and official page; 100% weight. · full weight |
| +8 | Manufacturing location disclosed: the brand identifies Tempe, Arizona, approximately 80,000 sq. ft. of operations, and product pages list U.S.-based cGMP/FDA-registered facility messaging. Rubric range is +6 to +10; applied +8. 1, 8, 12 Current official pages; 100% weight. · full weight |
| +7 | Facility certifications shared: Nootropics Depot links to ISO/cGMP certificate material for Omnient Labs and Supplement Logistics.

| −5 | Independence-language caveat: Nootropics Depot repeatedly uses 'third-party' or 'independent' lab language, but also discloses that the same founder owns and oversees Nootropics Depot, Omnient Labs, and Supplement Logistics. Applied -5 for potential shopper confusion about arm's-length independence; this is far below the -15 to -22 refusal/no-testing penalty because COAs and ISO accreditation are real transparency positives. 1, 2, 5, 25 Current official pages; 100% weight. · full weight |

| −26 | Recent federal criminal/regulatory misbranding case: On October 30, 2023, Centera Bioscience d/b/a Nootropics Depot and CEO Paul Eftang pleaded guilty to introduction of misbranded drugs into interstate commerce. On February 5, 2024, the company was sentenced to 3 years of probation, the CEO to 1 year of probation, and the defendants paid $2.4 million forfeiture and surrendered seized drugs. DOJ stated the conduct involved tianeptine, adrafinil, phenibut, and racetams sold between 2017 and 2021. Rubric has no exact 'criminal misbranded unapproved drug distribution' line, so this is scored analogously to a severe FDA warning/regulatory action. Base penalty selected: -35 due to guilty plea, unapproved drug distribution, national sales, and probation. Temporal discount: sentencing occurred 2024-02-05, which is 2-5 years before 2026-06-14, so 75% weight = -26.25, rounded to -26. 16, 17, 18 Sentencing 2024-02-05 is 2-5 years old as of 2026-06-14; 75% weight applied. · 75% weight |
| −6 | Import/seizure component within the same federal case: DOJ sentencing release states Customs detained shipments addressed to Centera Bioscience or subsidiaries and that defendants surrendered drugs seized by FDA and Customs and Border Protection. Rubric range for import alert/refusal is -15 to -22; to avoid double-counting the same case, applied a limited -6 contextual penalty: base -8 for import/seizure signal × 75% recency weight = -6. 17 Same 2024 sentencing case, 2-5 years old; 75% weight applied. · 75% weight |
| +4 | The case involved drug-like synthetic/nootropic compounds that Nootropics Depot no longer appears to feature in its current mainstream supplement catalog, while current sampled products are botanicals, nutrients, mushrooms, and standardized extracts with COAs. This does not erase the guilty plea, but it reduces the relevance of the legacy conduct to today's sampled supplement SKUs. 8, 9, 12, 13, 16, 17 Exceptional · Industry Context |

| Value baseline 50 → 77 Adequate |
| +15 | Premium justified by quality/testing infrastructure: Public COAs, ISO/IEC 17025 lab accreditation, cGMP manufacturing disclosure, and standardized actives justify some premium pricing. Rubric range is +12 to +18 for premium justified by quality/certs; applied +15 because the quality evidence is strong, although NSF/USP finished-product certification was not verified. 1, 2, 4, 8, 9, 12, 13 Current pricing/quality pages; 100% weight. · full weight |
| +10 | Price matches quality in specialty products: For complex products such as standardized Tongkat Ali 10%, Magtein, Cistanche, Cognance, and Berberine Phytosome, the higher price is paired with standardized actives, COAs, or branded delivery technologies. Rubric range is +10 to +15; applied +10 because this is clearest for specialty products, not commodity amino acids. 10, 11, 12, 13, 14 Current product pages; 100% weight. · full weight |
| +6 | Transparent pricing and no hidden subscription trap found: sampled pages show one-time prices and size options; no forced subscription model or cancellation-trap pattern was found.

| +4 | Bulk/free-shipping value: Nootropics Depot advertises free 2-3 day FedEx shipping on domestic orders over $50 and larger count sizes on several products. Rubric range is +2 to +4 for reasonable free shipping and +3 to +6 for bulk discounts; applied +4 combined because availability is useful but not unusually generous. 43, 8, 12 Current pages; 100% weight. · full weight |
| −8 | Commodity-product price premium: sampled commodity/basic comparisons show Nootropics Depot L-theanine at $15.99 for 90 capsules, while Nutricost 200 mg L-theanine is listed by Vitacost at $20.39 for 240 capsules ($0.09/serving). Magtein is $39.99 for 90 capsules at Nootropics Depot versus Life Extension Neuro-Mag at $31.50 for 90 capsules. This is a 2-of-4 sampled value concern for commodity/branded comparables. Rubric range is -12 to -18 for 20-50% overpriced; applied -8 because only some sampled products are above-market and quality/COA differences partially justify the premium. 8, 12, 31, 33 Current 2026 prices; 100% weight. · full weight |
