Verification notes
What we reviewed, with the limits of that evidence kept explicit.
01
Shipping, returns, and payment
Mile High Compounds is a Colorado company that fulfills orders from a temperature-controlled site in Arizona. The site accepts major credit cards and bank transfer. Orders placed before noon Mountain time are eligible for same-day fulfillment. The vendor lists service to the United States, US territories, Aruba, Canada, Denmark, El Salvador, France, Puerto Rico, and the United Kingdom. It states that US orders over $300 get free FedEx two-day shipping. International orders over $400 get free GlobalPost shipping. International orders ship DDP, with duties and taxes collected at checkout.
02
Public COA library: 154+ report links
The public COA page exposed 154 View COA links during the August 14 audit, with about 80 explicit batch identifiers. The host mix included 38 Kovera links, 26 Chromate links, seven ILS links, 58 Google Drive assets, and 33 same-domain attachments. This is broad public coverage, but retained images and attachments are not all equivalent to independently verified lab records. Match the exact lot and strength. The library does not prove the separate claim that all manufacturing sites are cGMP-certified and FDA-audited.
03
FDA warning letter 721600
FDA sent Mile High Compounds LLC warning letter 721600 on March 31, 2026. The letter says that website and linked community content established intended human drug use for GLP products and bacteriostatic water. FDA classified those products as unapproved new drugs under the cited facts. This is a public regulatory record, not a customer allegation.
04
Trustpilot and community reputation
The exact-domain Trustpilot profile showed 4.7/5 across 442 reviews. The profile is claimed and uses a paid Trustpilot subscription. The recent record includes positive shipping and support reports, product-integrity complaints, and an allegation that the owner offered products for positive reviews. PeptidePrices reports the allegation but does not present it as proven. Mile High receives 9.5/10 from COA 10, reputation 10, transparency 9, and operations 9. The weighted result is 9.6 and is rounded to the nearest half point. Affiliate status does not affect the score.
