- Testing transparency27/40
Public 7-category testing rubric grade plus disclosed testing methods plus a named third-party lab. The full range is gated on the vendor publicly naming the tests they run; a high rubric grade without disclosure caps at 18 of 40.
- Operational & regulatory standing22/25
Reflects FDA actions, payment-processor issues, ownership uncertainty, closures, and editorial audit notes the vendor-risk monitor has surfaced. A recent published COA earns a small bonus on top of the operational base.
- Operational stability15/15
Vendor age. 5+ years of operation earns full points; 1 year or less earns minimal credit. Absent foundedYear earns a neutral default; absence of data is not proof of risk.
- Verification tier10/10
Editorial tier assignment based on documentation completeness, response to corrections, and presence of verifiable business address. Tier 1 vendors meet the highest bar.
- Price discipline10/10
Heuristic check on aggressive discounting. Reasonable codes (<=25%) earn full points; 25-40% earns half; >40% off list often signals inventory clearance or churn and earns zero.
Modern Aminos has been operating since 2020 with a US-based catalog that emphasizes active customer reviews and mid-tier pricing across a broad SKU set. The A grade of 84 reflects six years of continuous trading, an HPLC purity disclosure, and a clean regulatory standing as of May 2026. The Trust Score is built from a 27-of-40 testing component, a full 22-of-25 regulatory standing with no audit notes, and the maximum 15-of-15 stability bonus that five-plus-year vendors earn. Pepticker docks 1 of 1 on heavy metals because the disclosed HPLC reporting does not cover the lead/cadmium/mercury/arsenic panel. Naming the underlying testing laboratory publicly would lift the testing component by roughly 6 points and likely push the composite into A+ territory. Buyers should confirm batch COAs match the lot number on the shipped vial — the rubric credits HPLC purity but cannot independently verify lot-level conformity from the storefront alone. Modern Aminos is frequently cross-shopped against Research Peptides and Pure Rawz for buyers comparing mid-tier US retailers with HPLC disclosure. The 10% discount code (MA10) sits within the price-discipline window and applies cleanly at checkout across recent crawl cycles.

Editorial read of how this vendor lands today
Phase-1 community-sentiment write-up — Pepticker editorial's read of forum activity (r/Peptides, our Discord, prior incidents) at the date below. Not a user-submitted review. The 7-category rubric scoring and trust score are computed separately.
Modern Aminos has built genuine community credibility behind its HPLC-verified catalog, with active customer reviews reinforcing testing claims — a combination that separates it from peers who test similarly but market more aggressively.
Why we recommend Modern Aminos
Modern Aminos launched in 2020 and has accumulated a community review record that corroborates its HPLC testing claims — a combination that is rarer than it sounds. Many vendors in our registry test adequately but have thin or unreliable community feedback; others have community hype that outpaces their testing documentation. Modern Aminos occupies a believable middle: testing score 6.0 out of 7, backed by organic customer review volume that tracks consistently with the claimed quality level. Tier-1 US vendor, discount code MA10 (10% off). We assess Modern Aminos against Pepticker's 7-criterion methodology (https://pepticker.com/methodology); the convergence of HPLC documentation and corroborating community signals earns the recommended verdict.
Testing & COA practices
HPLC purity testing is documented for the catalog. No mass-spec identity or additional panels — the same single-panel standard that places Modern Aminos alongside several other 6.0-scoring US vendors. The differentiation here is not in the number of testing panels but in the corroborating community signal: when independent user reviews consistently describe expected experimental outcomes at stated concentrations, that's meaningful secondary evidence even if it doesn't substitute for laboratory testing. COA links were confirmed active as of our April 2026 verification.
Shipping, quality, and customer service
Shipping is $9.95 domestic flat. Customer service reputation is one of the brighter spots in Modern Aminos' profile — the same active community that produces corroborating quality reviews also surfaces customer service interactions, and the pattern is consistently positive. Fulfillment speed and communication quality appear consistent with a vendor that has invested in the retail experience rather than purely in product. No international warehousing is available.
Product range and pricing
Modern Aminos operates a broad mid-tier catalog covering recovery peptides, GLP-1 compounds, and longevity SKUs. Pricing is competitive for a tier-1 HPLC-verified vendor. The MA10 discount code is straightforward — 10% off, no expiry conditions noted as of our last check.
Where they fall short
Single-panel HPLC is the ceiling on testing documentation. No international warehousing. Community reviews, while genuine, are a soft signal compared to named-lab certification. For researchers who need mass-spec identity confirmation, Peptide Partners or QSC Peptides are the step up.
Bottom line
Modern Aminos is a reliable, community-validated choice for mainstream US peptide research. Its value lies in the convergence of testing documentation and organic community credibility — a combination that justifies the recommended verdict.
