Trust signals
At a glance
COA & lab verification
Mile High publishes an extensive lot-indexed library across peptides, blends, bioregulators, capsules, and other compounds. The current page links directly to Chromate, Kovera Labs, and ILS Labs verification records, plus retained report images. This supports broad public third-party coverage. The vendor states an eight-point panel for identity, purity, net content, endotoxin, sterility, heavy metals, and related checks. The library is evidence for the listed lots; it does not independently prove the separate vendor claims that all manufacturing is cGMP-certified or FDA-audited. Match the received lot and strength to a live lab record. Affiliate status does not influence the rating.
Our verdict on Mile High Compounds
Mile High has broad public lab records and established fulfillment infrastructure. The FDA warning letter and unsupported manufacturing-certification claims are material limitations.

FDA sent Mile High Compounds LLC warning letter 721600 on March 31, 2026.

FDA classified those products as unapproved new drugs under the cited facts. This is a public regulatory record, not a customer allegation.
The exact-domain Trustpilot profile showed 4.7/5 across 406 reviews. The recent record includes verified positive shipping reviews, product-quality 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.
