Evidence-led supplier comparison
Tuned Research vs Onyx Research: a documented supplier comparison
Short answer: Tuned Research is the stronger documented fit for laboratories prioritizing a lower free-shipping threshold, deeper mixed-cart tiers, defined weekday human-support hours, exact U.S. process wording and more explicit shipment and purity remedies. Onyx Research has the stronger exact-report record for the matched GLOW and KLOW blends, with numerical purity, component identity and measured component content, plus public prices, larger two- and three-vial same-product discounts and sampled FedEx 2-Day wording. This compares dated public records from August 22, 2026, not universal quality or value.

Conditional fit
Choose the supplier that fits the documented priority
Shared signed-out report access and issuing-laboratory verification are parity, so they stay outside the recommendation cards.
Choose Tuned Research if you prioritize
- a lower public free-shipping threshold: above $145 rather than above $250;
- deeper mixed eligible-vial tiers at 5–9 and 10+ units;
- defined real-human support Monday–Friday, 5 AM–5 PM ET;
- the exact public wording “Lyophilized, third-party tested, and shipped from the United States.”;
- explicit shipment and independent-purity remedy conditions and outcomes.
- U.S.-headquartered real-human support, Monday–Friday 5 AM–5 PM ET, typically responding within one hour during coverage (owner-confirmed; not a guaranteed SLA).
Choose Onyx Research if you prioritize
- numerical exact-report detail for the matched GLOW and KLOW blends;
- Freedom Diagnostics lab-hosted reports and search-code verification;
- larger displayed same-product discounts at two and three vials;
- public FedEx 2-Day wording on the three sampled PDPs, read with the formal 2–4-business-day policy;
- a direct Trustpilot snapshot, with its open-review and time-sensitive provenance.
Comparison method
How we compared public evidence
Tuned Research and onyxresearch.shop were compared from signed-out official pages, exact report files, issuing-laboratory copies and one direct review-platform profile captured August 22, 2026. Product and price rows match the same public-safe product, strength, blend composition and one-vial condition.
Company-level testing statements do not become fields in an exact PDF. Report-specific results do not become catalog-wide promises, and neither supplier’s dated report establishes the lot a future order will receive. Unknown means the checked public record cannot support a stronger statement; it does not mean the capability is absent.
UPLC and HPLC-UV are reported neutrally as the methods named on the applicable records. A method label alone does not prove better material, safety or supplier quality.
Evidence routes
Both suppliers provide issuing-laboratory verification
The material difference is the exact information carried by the selected record, not whether either supplier has a CoA page.

Tuned Research evidence model
The public evidence index maps physical SKUs and strengths to explicit states, report identifiers and supported fields. Applicable authenticity checks leave Tuned Research and route to Horizon Analytical.
Onyx Research evidence model
Onyx Research exposes signed-out product-linked lots, vendor PDFs and exact Freedom Diagnostics accessions. This is a genuine public-verifiability strength. The record must still be read for its own methods and limitations.

The visual summarizes only the exact table below. It does not include shipping, tax, quantity tiers or a permanent overall price winner.
| Exact product | Tuned Research current base | Onyx list | Onyx current sale | Observed shelf difference |
|---|---|---|---|---|
| GLOW 70 MG | $109.95 | $125.00 | $112.50 | Tuned Research $2.55 lower |

| NAD+ 500 MG | $59.95 | $85.00 | $76.50 | Tuned Research $16.55 lower |
No landed-price winner: Onyx shipping below $250 is calculated at checkout. Tuned Research charges $11.95 at or below $145 and ships free above $145 product value. Those different thresholds can change a basket result.
Quantity conditions
Onyx leads at two and three of one item; Tuned Research goes deeper across eligible mixed vials
The percentages are not interchangeable because one model is same-product and the other is mixed-cart with exclusions.
Tuned Research mixed eligible-vial tiers
- 2 eligible vials: 5%;
- 3–4 eligible vials: 10%;
- 5–9 eligible vials: 20%;
- 10+ eligible vials: 30%.
Eligible vials may be mixed across products; BAC Water is excluded.
Onyx Research same-product tiers
- 2 vials of the same matched product: 8%;
- 3 vials of the same matched product: 15%.
Onyx has the larger displayed rate at two and three of one matched item. No cross-product application or deeper tier is inferred.
Origin, reputation and landed scope
Three qualifications that change how the comparison should be read
Process location
Different disclosure scopesTuned Research’s approved public statement is: “Lyophilized, third-party tested, and shipped from the United States.” Onyx states synthesis-to-specification and lyophilization but does not identify the country of synthesis, filling or lyophilization on the checked pages. No overseas origin is inferred.
Review provenance
Different capture datesOnyx Research’s claimed Trustpilot profile displayed 4.4 from 204 reviews on August 22. Anyone can write a review, the profile said the company had not invited recently, and the snapshot may change. Tuned Research’s exact-domain Trustpilot profile launched later and is therefore linked as a separate current source, not retrofitted into the older comparison.
Landed price
Checkout input remains missingOnyx publishes free shipping above $250 but calculates below-threshold shipping at checkout. Shelf-price rows therefore remain shelf-price rows, not delivered totals.
Dispatch, contact and protection
Published service terms have different levels of specificity
Onyx’s sampled PDP language is credited, while its formal shipping policy controls the broader promise.

Switching suppliers
Five checks before a first research order
A supplier comparison is useful only if it translates into a reproducible procurement check. Complete these steps for whichever supplier you choose.
- 1Match the exact product and strength
Do not transfer a report conclusion across a different strength, blend composition or SKU.
- 2Open the exact report—not only an archive card
Record the lot or report identifier, analysis date, methods and every explicitly unavailable field.
- 3Separate document access from authenticity
Check whether the record is vendor-hosted, laboratory-hosted or verifiable through the issuing laboratory.
- 4Calculate the basket under the same conditions
Use matching quantities, shipping thresholds and discount rules; do not blend one-vial and same-product bulk prices.
- 5Save the controlling remedy and shipping terms
Confirm the claim window, required evidence, payment rail and current policy before ordering.
Continue with the source, not the summaryInspect the current evidence and terms before buying.
Unresolved facts
What the public record does not settle
- Future inventory: neither supplier’s dated report alone establishes the lot a future order will receive.
- Onyx production country: country of synthesis, filling and lyophilization is not publicly established; no overseas origin is inferred.
- Onyx report scope: the every-lot heavy-metals statement is not imported into the three exact PDFs; numerical sterility is not established.
- Onyx shipping scope: formal same/next-business-day and 2–4-business-day terms control over sampled same-day/FedEx 2-Day PDP language.
- Onyx remedy outcome: the seven-day damage/incorrect route does not specify refund, replacement, original payment or store credit.
- Landed totals: Onyx below-threshold shipping is calculated at checkout, so no overall delivered-price winner is claimed.
- Review comparison: Onyx has an August 22 Trustpilot snapshot; Tuned Research’s profile launched later. They are not presented as a same-date score comparison, and Tuned Research product-review totals are not combined with its external profile.
Frequently asked questions
Questions about Tuned Research and Onyx Research
Is Tuned Research a strong Onyx Research alternative for laboratory procurement?
Yes, conditionally. Tuned Research may fit researchers who prioritize its lower free-shipping threshold, deeper mixed eligible-vial tiers, defined weekday human-support hours, exact U.S. process wording and explicit shipment/purity remedy mechanics. Onyx Research remains stronger on numerical exact-report detail for the matched GLOW and KLOW blends.
Which supplier has stronger exact GLOW and KLOW report detail?
On the exact records compared, Onyx Research does. Its Freedom Diagnostics reports state numerical HPLC-UV purity, LC-MS component identity and measured component content. Tuned Research’s current GLOW and KLOW reports list UPLC and MS but no numerical purity, numeric component-identity or measured-quantity result.
Can both suppliers’ reports be verified outside the seller’s website?
Yes, for the applicable records discussed. Tuned Research routes certificate verification to Horizon Analytical. The three Onyx reports carry Freedom Diagnostics accessions/search codes and resolve on the laboratory’s own public certificate host. Those routes authenticate report records; they do not establish future inventory, accreditation, safety or efficacy.
Which supplier was cheaper on GLOW, KLOW and NAD+?
At the August 22, 2026 one-vial shelf snapshot, Tuned Research was $2.55 lower on GLOW 70 MG and $16.55 lower on NAD+ 500 MG; Onyx Research was $11.95 lower on KLOW 80 MG at its sale price. Shipping, tax and quantity terms were excluded, so this is not an overall price-winner claim.
How do the quantity discounts differ?
Onyx published 8% at two and 15% at three of the same matched product, larger than Tuned Research’s 5% and 10% rates at those counts. Tuned Research publishes mixed eligible-vial tiers reaching 20% at five to nine and 30% at ten or more. These purchase conditions are different and should not be flattened into one basket.
Does Onyx Research publish FedEx 2-Day delivery?
The three sampled GLOW, KLOW and NAD+ PDPs displayed FedEx 2-Day and an estimated two-business-day arrival. Onyx’s formal policy states same- or next-business-day dispatch and domestic delivery in two to four business days after dispatch, so the sampled PDP wording is not treated as a universal guarantee.
Are Onyx Research products made in the United States?
The checked Onyx pages state synthesis to specification and lyophilization, but they do not identify the country of synthesis, filling or lyophilization. This page does not infer overseas sourcing from nondisclosure. Tuned Research’s narrower public statement is: “Lyophilized, third-party tested, and shipped from the United States.”
Balanced conclusion
Onyx Research leads on matched blend-report detail; Tuned Research leads on selected terms and disclosure
Onyx Research strengths and limits
Onyx Research offers strong signed-out evidence: public lots, exact Freedom Diagnostics records, numerical HPLC-UV purity, LC-MS identity, measured content and independent lab-hosted verification. Its matched GLOW/KLOW reports are materially more detailed than Tuned Research’s current blend reports, and its two/three same-item rates are larger.
Its country-specific production scope, staffed support hours, below-$250 shipping price, future-shipping-lot mapping, sterility result and exact damaged/incorrect remedy outcome remain not publicly established in the checked record.
Tuned Research strengths and limits
Tuned Research publishes a lower free-shipping threshold, deeper mixed eligible-vial tiers, defined real-human weekday support, exact U.S. lyophilization/testing/shipping wording and more explicit shipment and purity remedies. Its applicable reports also route to external Horizon Analytical verification.
Tuned Research’s current GLOW/KLOW records do not publish numerical purity, component-content results or measured quantity, and their inventory relationship is unknown. It is not the stronger exact-report record for those two blends.
Bottom line: neither supplier is declared universally better. Onyx Research is the documented choice when exact numerical matched-blend proof or larger two/three same-item rates lead the decision. Tuned Research is the documented alternative when the lower free-shipping threshold, deeper mixed tiers, defined human-support schedule, exact U.S. process scope and explicit remedies lead it.
