Is Mile High Compounds legit?
Mile High Compounds is operating and surfaces credible public signals (composite 55/100), but we have not placed a first-hand test order yet — this is a public-data audit. 53 Kovera records, no FAIL marks, 99.93% median purity; the 3 GLP products in FDA letter 721600 still sell under MHC code names. Public-data audit, 55/100. The signal table below shows what we verified and what is still open.

What we mean by "legit"
We do not use "legit" as a single yes-or-no signal. A vendor is legit when four things hold: identifiable corporate operator, third-party or independently-mirrored COAs, shipping and payment infrastructure that consistently delivers, and a complaint history that surfaces real issues rather than vanishes them. Our composite score is the weighted average of those four — shipping, pricing, support, COA quality — and you can read the full rubric at /methodology.
For Mile High Compounds the audit is "public-data tier" — we aggregate vendor disclosures, third-party COA mirrors, operating-history evidence, and complaint patterns. A first-hand test order is still pending and the page will be upgraded when that lands.
Verdict
53 Kovera records, no FAIL marks, 99.93% median purity; the 3 GLP products in FDA letter 721600 still sell under MHC code names. Public-data audit, 55/100.
