Independent vendor review
Review profile checked 2026-08-18 · Independently fact-checked
HEEZ Research scored across our four rubric factors — COA practices (40%), reputation, transparency, and operations (20% each).
Weighted factor result: 6.3/10. The published score follows the weighted result after rounding.
Direct answer
HEEZ Research appears to be an operating vendor, but its COA coverage is incomplete. PeptidePrices confirmed three real Chromate reports; those same examples repeat across unrelated product pages and do not establish batch-specific catalog coverage. Fast domestic shipping, flexible checkout, and public contact details are positives. Its new domain, unverified ownership and legal entity, strict returns, and seven-review Trustpilot record keep it below top-tier vendors. The evidence supports a 6.5/10 rating.
Buying details
The site states same- or next-business-day dispatch from Florida and 2–4 business day domestic delivery. Sales are generally final, with a limited Terms exception for verified manufacturing defects reported within seven days.
Trust signals
The checked product pages repeated the same three Chromate certificates labeled as examples: Retatrutide 10mg report 36277, GHK-Cu 100mg report 36488, and Melanotan II 10mg report 37509. PeptidePrices confirmed all three report codes in Chromate's registry. They are useful issuer-confirmed examples, but they are not batch-specific coverage for the full catalog and do not include endotoxin, sterility, or heavy-metals panels.
Evidence summary
HEEZ has a functioning storefront, fast stated fulfillment, flexible payments, public contact details, and three independently confirmed Chromate examples.
The key limitation is report coverage: the same examples repeat across unrelated products and are not batch-specific evidence for the catalog. The very short operating history, thin mixed reviews, strict returns, and undisclosed ownership keep the score in the middle of the scale.
What we reviewed, with the limits of that evidence kept explicit.
HEEZ Research operates at heezresearch.com. The domain was registered May 5, 2026. The site publishes a Fort Lauderdale mailing address, phone number, and support email, but PeptidePrices did not verify an owner or legal entity. The address should not be read as proof of a laboratory or fulfillment facility.
Retatrutide, KLOW, GLOW, and BPC-157 pages repeated the exact same three certificates labeled as examples: Chromate 36277 for Retatrutide 10mg, 36488 for GHK-Cu 100mg, and 37509 for Melanotan II 10mg. PeptidePrices confirmed all three codes in Chromate's registry. They are real issuer records, but they do not prove that every product or received lot has a matching report.
Trustpilot showed 3.6/5 from seven reviews, while vendor-hosted reviews are excluded from the reputation score. The site states same- or next-business-day dispatch and 2–4 business day domestic delivery, supports cards, wallets, bank payments, and cryptocurrency, and generally makes sales final. Code PEPTIDEPRICES gives 15% off an eligible first order and must be entered manually.
Decision guide
Customer reputation
Customer reviews describe service and order experiences. They do not prove identity, purity, vial content, sterility, or manufacturing standards. We keep them separate from COA and independent-testing evidence.
PeptidePrices confirmed Chromate reports 36277, 36488, and 37509 in the issuer registry. The same examples repeat across checked product pages and are not exact-lot evidence for the full catalog.
