The two vendors directly below Purgo Labs on our scoreboard, tied at 9/10 verified points each — but they earn the score on different criteria, which is exactly what makes this comparison worth reading. Below: the criterion-by-criterion diff, the review records, the honest negatives on both sides, and the one verified code.
Verdict
It's a genuine split decision, and the tiebreaker is what you value. Mile High Compounds has the stronger COA practice — certificates that verify through the testing labs' own portals — and the larger independent review base (4.8 (502 reviews)). Amino Club has the cleaner record: no FDA warning letter, and the only claims history of the two that held up without contradiction when we cross-checked it (4.6 (573 reviews)).
Choose Mile High if lab-side verifiability is your top criterion and the documented caveats don't move you. Choose Amino Club if a consistent claims record and acknowledged-rather-than-hidden weaknesses matter more. Both trail Purgo Labs (10/10) on the same rubric.
Rendered directly from the scoreboard's evidence records — the same data behind the vendor scoreboard. A check means the point was awarded on independently verifiable evidence; a dash means it wasn't.
| Criterion | Amino Club | Mile High |
|---|---|---|
| Names its testing laboratory | ILS Laboratories (San Diego, CA) named on certificates; 8-assay panel per batch | Kovera Labs and Chromate — both named via lab verification links on the public COA library (verified 12 Aug 2026) |
| Certificates verifiable at the lab, not just the vendor | Certificates carry an ILS access code for lookup at ils-lab.com (e.g. COA-2026-Y_PBKT, code NZHW9KJZ) — same standard applied to Kovera/Janoshik verify codes (read 6 Sep 2026) | COAs resolve through lab-side verify-by-code portals (koveralabs.com/#/verify, chromate.org/verify) serving COA + endotoxin + 14-day sterility reports per sample; a minority of older COAs are Google Drive links |
| Batch-specific COAs matched to lots | Lot-numbered certificates in a 103-certificate public library (e.g. lot SBPC0001) | Public COA library covers ~70 products with per-batch certificate histories (for example, ‘3 previous batches’ per product) |
| Publishes measured net content vs label | Certificate reports Net Peptide Content 15.85mg vs 15mg label (BPC-157 Spray, lot SBPC0001, ILS, 20 Aug 2026) | Kovera report KVR-2026-9A59E7 (BPC-157 batch BPC-010-MH-04) states Batch Avg Net Content 10.86mg vs 10mg label, 99.857% purity — read on koveralabs.com verify portal 6 Sep 2026 |
| COAs and pricing viewable without an account | COA library and pricing viewable without account | COA library, catalog, and product pages viewable without account |
| Independent review base (50+ on an external platform) | 4.6 / 573 on Trustpilot (re-read 2 Oct 2026; was 4.6 / 550 on Trustpilot) | 4.8 / 502 on Trustpilot (re-read 2 Oct 2026; was 4.8 / 503 on Trustpilot) |
| No contradictions among its own claims | No contradictions found (checked Aug 2026) | |
| Vial sizes stated with prices | Sizes stated with prices | Sizes stated in product names, product-page specs (for example, ‘BPC-157 10MG’, ‘Vial Size: 10mg in 3mL glass vial’) and throughout the COA library |
| Publishes a legal entity and street address | Mile High Compounds LLC · 16055 Old Forest Pt. Suite 301, Monument, CO — on-site (6 Sep 2026) | |
| No misleading trust signals or buyer-protection workarounds | No on-site review badge contradicting the independent record; card payment accepted; no regulator action found (checked 6 Sep 2026) | |
| Score | 9/10 | 8/10 |
The two differences that decide this comparison: Mile High earns the lab-hosted verification point — its certificates resolve through koveralabs.com and chromate.org rather than only the vendor's site — while Amino Club earns the claims-consistency point that Mile High loses to its own marketing figures. Everything else is closer to even.
No legal entity name appears anywhere on the site — brand name only, with a street address buried in the SMS terms — which is the one rubric point it does not hold. A minority of recent reviews report shipping delays, which the company has publicly acknowledged. GLP-1 class selection is narrower than Purgo Labs.
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.
We only publish prices read on a vendor's own pages on a stated date. We currently hold 8 verified price rows for Mile High Compounds and none yet for Amino Club — so we won't call a price winner here, and any page that does without dated evidence is guessing. Amino Club's pricing is fully ungated, so checking a specific compound takes seconds. Verified rows across vendors live on the price comparison.

They tie at 9/10 on our verification rubric, but earn the score differently. Mile High's certificates verify through the testing labs' own portals (Kovera Labs, Chromate) — the stronger COA practice — while Amino Club was the vendor whose own claims held up without contradiction when we cross-checked them, and it carries no FDA warning letter. Mile High has the larger review base (4.8 (502 reviews) vs 4.6 (573 reviews)). If lab-side COA verification matters most, Mile High; if a clean claims record matters most, Amino Club. Amino Club is our disclosed affiliate partner; Mile High is not (the partnership ended 18 September 2026), and the scores on this page were computed by the same rubric before and after that change.
Yes — that already puts both ahead of most of the industry. Amino Club attributes testing to ILS Labs with a stated seven-plus tests per compound. Mile High names Kovera Labs and Chromate, and goes a step further: its certificates resolve through the labs' own verify-by-code portals rather than only the vendor's website.
FDA Warning Letter 721600 (March 2026) is on record for Mile High Compounds. A warning letter is not a shutdown and the company continues to operate, but it belongs in any honest comparison — as does the fact that some figures on Mile High's own pages overstate its independently checkable record (a '4.9-star Trustpilot' claim against a verified 4.7, and '8x testing' against its own product pages' '7x'). Amino Club has no equivalent letter, and its claims were consistent when we checked them.
We only publish prices we've read on a vendor's own pages on a stated date. We hold verified price rows for Mile High but not yet a like-for-like set for Amino Club — its pricing is fully ungated, so you can check any price without an account. Until we've captured comparable rows, we won't call a price winner. Our verified price comparison covers the pairs we can stand behind.
One. WELLNESS at Amino Club (20% off) is our disclosed partner code, confirmed to apply on every order (verified 23 August 2026). We no longer hold a verified Mile High Compounds code: that partnership ended 18 September 2026 and we do not print codes we cannot test at checkout.
As of 6 September 2026 the rubric no longer does, on points: Under rubric v2 (ten criteria, 6 September 2026) Purgo Labs scores 10/10, Amino Club 9/10 and Mile High 8/10. Amino Club loses exactly one point: it does not publish a legal entity name anywhere on its site. Among equal scores the scoreboard lists our affiliate partners first, then independent rating, and says so on the page. Mile High scores 7/8, held back only by contradictions among its own marketing figures. Purgo remains our primary partner and the vendor whose certificate chain we have read most deeply; the evidence for every point on all three is on the scoreboard, and the dates each point was awarded are in the score history.
Where the evidence points
Neither vendor holds every rubric point; Purgo Labs does, and it is where we point readers who want the full verification loop. Publishes per-lot COAs naming the testing laboratory — SteriGenix and Freedom Diagnostics — with lot numbers, test dates, measured net peptide content and direct verify-at-lab links. HPLC and mass spectrometry testing, US-based fulfilment from Scottsdale, Arizona, same-day dispatch on weekday orders before 2PM EST, and a 60-day money-back guarantee.
Purgo Labs is our primary affiliate partner; we earn a commission on that link. The score is computed from published evidence and does not read partner status.
