Disclosure: Purgo Labs is our affiliate partner; we earn nothing from Mile High Compounds. Scores come from the public rubric, which has no partnership input.
Research use only. Compound Review scores vendors on documentation — laboratory certificates, lot records, pricing and company identity. Nothing on this page is guidance on human or veterinary use, dosing or health outcomes.

What we found at Mile High Compounds
Read 24 September 2026 on the vendor's own pages
Strong certificates — lab-portal verification and measured net content — sitting next to marketing copy that overstates its own review record and an FDA warning letter. The score reflects both. Not an affiliate partner — the vendor closed our affiliate account on 18 Sep 2026; we earn nothing from it.

Where Mile High Compounds ranks by compound
Mile High Compounds appears in 7 of our compound rankings. Each ranking orders every scored vendor that sells the compound by rubric score, then verified price per mg.
2026-08-146/8 — initial public baseline (rubric v1)
2026-09-067/8 — net-content awarded — Kovera report KVR-2026-9A59E7 (batch BPC-010-MH-04) read on koveralabs.com: 10.86mg vs 10mg label
2026-09-068/10 — re-issued under rubric v2 (was 7/8); not awarded: claims-consistent, clean-record
2026-09-118/10 — evidence refreshed, score unchanged — Trustpilot 4.8 / 485 (up from 4.7 / 441); on-site claims re-checked: '4.9 · 389 verified reviews' and '14x tested' vs product pages' '7x' — claims-consistent still withheld
2026-09-188/10 — PARTNERSHIP ENDED (vendor closed our affiliate account) — score unchanged; partnership is not a rubric input. Ordering effect only: no longer listed among partners on equal-score tiebreaks
Purgo Labs: the caveat
Smaller independent review base than several competitors (80 reviews). The catalog is peptide-focused, so researchers also working with SARMs or broader research chemicals will need a second supplier.
Mile High Compounds: the caveat
Its own pages overstate the checkable record — the homepage says ‘4.9 · 389 verified reviews’ and ‘14x tested’ while Trustpilot showed 4.8 across 485 reviews and its own product pages say ‘7x independent third-party testing’ (all read 11 Sep 2026) — and FDA Warning Letter 721600 (March 2026) remains on record. Its GLP-class products are sold as MHC-1 SM, MHC-2 TRZ and MHC-3 RT with no stated identity or CAS number, so they are excluded from our Price Index. A warning letter is not a shutdown; the discrepancies are worth knowing.

Where the evidence points
Where the evidence points
Purgo Labs 10/10
We earn nothing from Mile High Compounds. Purgo Labs holds every rubric point — certificates checkable at the lab, measured net content per lot — and is cheaper after codes on 8 of 8 like-for-like vials.
Purgo Labs, on the evidence: 10/10 rubric points against 8/10. Mile High Compounds is stronger on 4 points listed below. Every point is a fact you can check on either vendor's site; both are scored by the same published rubric.
Is Mile High Compounds legit?
Mile High Compounds scores 8/10 on our rubric, has an independently viewable rating of 4.8 (502 reviews), and names its lab (Kovera Labs · Chromate). Caveat: Its own pages overstate the checkable record — the homepage says ‘4.9 · 389 verified reviews’ and ‘14x tested’ while Trustpilot showed 4.8 across 485 reviews and its own product pages say ‘7x independent third-party testing’ (all read 11 Sep 2026) — and FDA Warning Letter 721600 (March 2026) remains on record. Its GLP-class products are sold as MHC-1 SM, MHC-2 TRZ and MHC-3 RT with no stated identity or CAS number, so they are excluded from our Price Index. A warning letter is not a shutdown; the discrepancies are worth knowing.
Which is cheaper, Purgo Labs or Mile High Compounds?
On the 8 compound-and-size rows where we have dated prices from both, Mile High Compounds lists lower on 0 and Purgo Labs on 6 (2 equal). Purgo's list prices drop 20% with code HEALTH.
Do you earn money from either vendor?
Purgo Labs is our affiliate partner and we earn a commission on referred orders; we earn nothing from Mile High Compounds. Scores come from the rubric, which has no partnership input, and the ordering rule on our scoreboard is disclosed.
Can Mile High Compounds COAs be independently checked?
Its public COA library names Kovera Labs and Chromate and links samples to lab-side verify-by-code portals. The library contains per-batch histories across roughly 70 products; a minority of older certificates use Google Drive links instead.
Is Mile High Compounds legitimate?
Mile High Compounds is operating at milehighcompounds.is and held a 4.8 Trustpilot score across 485 reviews when re-read on 11 September 2026. FDA Warning Letter 721600, dated 31 March 2026, remains relevant context; a warning letter is not a shutdown.
How does Purgo Labs pricing compare to Mile High Compounds?
Both vendors publish current prices. Mile High’s BPC-157 10mg sale price was $49.99 (12 August 2026 reading), versus Purgo’s $44.99 list price and $35.99 with HEALTH (20%). NAD+ 500mg was $59.99 at Mile High versus $47.99 at Purgo with HEALTH; GHK-Cu 50mg $49.99 versus $23.99. We hold no verified Mile High code as of 18 September 2026, so no discount is applied on its side.
