SKO Compounds Review: 33 Freedom Diagnostics COAs Verified Straight Out of the App's Own Bundle

An independent SKO Compounds review covering 29 normalized price rows and 35 recovered Freedom Diagnostics COA PDFs pulled directly from the storefront's own JavaScript bundle — 33 verifying live at the lab's public lookup, plus 11 products the vendor itself marks Coming Soon.

---

SKO Compounds is now a curated vendor on PeptideBenchmark. It runs a custom app rather than Shopify or WooCommerce, which usually means less to scrape from the outside — but SKO’s own front-end ships its entire product catalog, including a direct COA PDF link for almost every dosage, as one JavaScript array inside a public bundle. That let us pull and verify testing evidence for the whole catalog in one pass.

A gate on the page, not on the data

SKO Compounds’ storefront requires clicking through a 21+/research-use researcher-verification overlay before the rendered /products or /coas page shows anything. That overlay, though, only gates the rendered DOM. The /products HTML references a content-hashed index-*.js bundle, and that bundle embeds the entire 33-product catalog — name, category, tags, dosage ladder, per-dosage price and compare-at price, and a COA PDF path for nearly every dosage — as a single array literal, reachable with a plain unauthenticated fetch. A public Supabase remote-procedure endpoint, called with an anonymous key sitting in that same bundle, supplies live per-dosage stock overrides on top of it. Together, that let PeptideBenchmark read pricing, stock, and testing links without needing to automate the gate at all.

What actually verifies

SKO’s product bundle links a direct COA PDF for the current batch, plus one or more retained prior-batch PDFs, on nearly every dosage row. PeptideBenchmark downloaded and text-extracted all 35 recovered PDFs — 25 tied to the current batch, 10 retained from prior batches — rather than sampling just the newest one per product.

Every single PDF prints the same FreedomDiagnosticsTesting.com letterhead, a ten-digit Accession #, and an SKOC{accession}-format Search Code. Submitting each code to Freedom’s own public certificate lookup, gated on the “SKO Compounds” client name, resolved 33 of the 35 live:

Result	Count	What it means
Provider-verified	33	Resolves live at coas.freedomdiagnosticstesting.com under the SKO Compounds client name
Named-lab, unresolved	2	Prints the same Freedom letterhead but the accession now 404s at the live lookup

A sample of what resolved:

Compound	Dosage	Accession	Purity	Reported
GLP-3 RT (retatrutide)	10MG	SKOC2607070516	99.84%	2026-07-09
GHK-Cu	50MG	SKOC2607070536	99.78%	2026-07-09
CJC-1295 No DAC + Ipamorelin	10MG	SKOC2607070512	99.95%	2026-07-09
Tesamorelin	10MG	SKOC2607070504	99.86%	2026-07-09
BPC-157	10MG	SKOC2607070524	99.39%	2026-07-09

Average purity across all 35 documents is 99.7%, and every document reports HPLC purity, identity, and net-content together — 25 of the 35 (the current-batch documents) add an endotoxin pass/fail on top. None report heavy-metals or sterility panels.

The two unresolved documents are older, generically named files (semax-coa.pdf, selank-coa.pdf) rather than the newer SKOC{accession}.pdf naming SKO uses on its current batch. Both still print a Freedom Diagnostics letterhead and an accession number, but that accession now returns an HTTP 404 at Freedom’s live public lookup — the kind of drift that happens when a lab’s own archive ages out an older record. PeptideBenchmark keeps both as named-lab, vendor-hosted evidence rather than crediting them with a verification they didn’t earn live.

The testing gap SKO owns itself

Eleven products carry no COA at all: MT-1, KPV, the TESA/IPA Blend, Cagrilintide, Sermorelin, Thymosin Alpha-1, Kisspeptin, PT-141, ARA-290, ADAMAX, and AOD-9604. This isn’t something PeptideBenchmark inferred — SKO’s own /coas page lists each of them under a “Coming Soon” badge. We recorded all eleven as explicit no-document evidence gaps rather than omitting them from the count, so the testing-coverage figure reflects the real state of the catalog rather than just the products that happen to have a document.

Pricing

29 in-stock dosage rows normalize to a per-mg comparison on the pricing board. A few things needed care:

Every dosage is its own row. SKO’s product pages expose a dosage selector (10MG, 20MG, 30MG, …) rather than one price per product, so a multi-dosage product like GLP-3 RT produces one catalog row per strength.

Five branded names needed mapping. GLP-3 RT is tagged LY3437943 — Eli Lilly’s development code for retatrutide — directly in SKO’s own product data, and its description names the same 39-amino-acid triple-agonist mechanism. SKO-TRZ similarly maps to tirzepatide on tag and category evidence. Wolverine Blend, GLOW, KLOW, the CJC-1295/Ipamorelin pairing, and the TESA/IPA blend are house names the vendor’s own titles or tags spell out in full, mapped to their labeled components.

Eight in-stock-looking rows are actually sold out. SKO’s live Supabase stock endpoint marks 8 dosage rows — including the 100MG GHK-Cu, the Wolverine Blend, 1000MG SKO-NAD, and Cagrilintide — sold out even though their prices remain listed. Those prices are recorded but withheld from the pricing board rather than shown as available.

Bacteriostatic water is out of scope. It’s a reconstitution solution sold by volume, not a peptide vial, so it carries no mg-normalized price and stays off the board entirely.

Access

skocompounds.com’s rendered pages sit behind a researcher-verification overlay, but the overlay protects the DOM rendering, not the underlying data. The index-*.js bundle referenced from the /products page, and the public Supabase get_stock_overrides remote procedure called with the bundle’s own embedded anonymous key, both resolve with a plain unauthenticated request — no browser automation or gate-clicking was needed to read the catalog or the COA links.

Outside reviews (Trustpilot)

SKO also has a claimed Trustpilot profile. On August 1, 2026, Apify’s company-details sync recorded a 4.7 TrustScore from 259 reviews for skocompounds.com (claimed profile; not Trustpilot-verified business status in that snapshot).

That is useful customer-service and fulfillment context for a young storefront, but it answers a different question from laboratory evidence. Review volume and star ratings do not independently establish what is in a vial, and PeptideBenchmark keeps the Trustpilot bonus separate from COA coverage and Freedom Diagnostics provider verification on the live profile.

Why SKO Compounds is curated

Curated does not mean endorsed. For SKO it means:

• an openly priced 29-row catalog with per-dosage pricing and live stock state;
• 35 recovered Freedom Diagnostics COA PDFs, 33 of them verifying independently at the lab’s own public lookup;
• five branded or blended product names mapped to their components on the vendor’s own tag and title evidence, not guessed; and
• 11 untested products disclosed as an explicit gap rather than silently omitted, because SKO’s own /coas page says so.

The live SKO Compounds profile carries the current score and trust band; the COA database carries the preserved certificates.

Bottom line

SKO Compounds’ own front-end handed over more structured evidence than its 21+ gate might suggest — a full catalog and a COA PDF link for nearly every dosage, all inside one public JavaScript bundle. 33 of 35 recovered certificates check out live at Freedom Diagnostics, and the vendor is upfront about the eleven products it hasn’t tested yet. Its claimed Trustpilot profile (4.7 / 259 reviews on August 1, 2026) is an outside customer-service signal kept separate from that lab evidence on the live profile.

Common questions

Is SKO Compounds legitimate?

PeptideBenchmark does not issue binary legitimacy or product-safety endorsements. SKO Compounds is a West Hollywood, California storefront whose own product bundle exposes 35 Freedom Diagnostics COA PDFs, 33 of which resolve independently at the lab's own public certificate lookup under the SKO Compounds client name. That is a genuinely checkable evidence trail; it does not establish the identity, condition, or safety of a physical vial.

Does SKO Compounds publish COAs?

Yes, for most of its catalog. The public /coas page shows lot cards for current batches, and the underlying app bundle links a direct COA PDF for nearly every dosage — 25 current-batch and 10 retained prior-batch PDFs, 35 total. 11 products (including MT-1, KPV, Cagrilintide, and PT-141) are marked "Coming Soon" by the vendor's own /coas page and carry no COA yet.

Are SKO's COAs independently verifiable?

Most of them, yes. All 35 recovered PDFs print a FreedomDiagnosticsTesting.com letterhead with a ten-digit Accession # and an SKOC-prefixed Search Code. 33 of those resolve live at Freedom's own public certificate lookup gated on the "SKO Compounds" client name. The remaining 2 — both older, generically named PDFs for Semax and Selank — return an HTTP 404 at Freedom's live lookup and are recorded as named-lab, vendor-hosted evidence rather than provider-verified.

How does SKO Compounds gate its site, and does that block scraping?

The rendered /products and /coas pages sit behind a 21+/research-use researcher-verification overlay. That overlay protects the rendered page, not the data: the site's own content-hashed JavaScript bundle (which embeds the full product catalog, including COA PDF paths) and its public Supabase stock-override endpoint both resolve with a plain unauthenticated request, so PeptideBenchmark read the catalog and testing evidence without needing to click through the gate in an automated session.

Does SKO Compounds have a Trustpilot profile?

Yes. On August 1, 2026, the claimed Trustpilot profile for skocompounds.com showed a 4.7 TrustScore from 259 reviews. PeptideBenchmark treats that as a separate customer-service signal from laboratory evidence — it does not verify a vial or substitute for Freedom Diagnostics certificate checks.

Does PeptideBenchmark have an affiliate relationship with SKO Compounds?

As of August 4, 2026, yes — a disclosed affiliate relationship with referral link ?ref=635 and checkout code PEPTIDE10 for 10% off. The August 1, 2026 evidence findings in this review were written before that relationship existed and were not changed by it.
