SKO Compounds holds one of the larger independent review records we cover —4.7 across 347 Trustpilot reviews — and states its vial size next to every price. It also displays review counts on products that have not shipped yet. All three facts belong in the same review.
Verified first-party on 14 August 2026: skocompounds.com (behind its researcher gate) and Trustpilot directly. Disclosure: SKO Compounds became one of our affiliate partners on 24 August 2026 — we earn a commission on orders referred through skocompounds.com, and reader code COMPOUNDREVIEW gives 10% off at checkout (confirmed 24 Aug 2026). Every finding in this review, including the pre-order review counts, predates the partnership and stands unchanged.
On 14 August 2026, SKO's homepage listed five "Research Spray" products marked pre-order with a stated ship date of 22 August 2026 — each already carrying a star rating and review count. A NAD spray showed 4.9 from 186 reviews more than two weeks before its first unit ships.
Reviews cannot precede shipment. We offer no theory about how those numbers came to be — the observation is checkable on their own homepage and it has one practical consequence: SKO's on-site product ratings should not be relied on. Its Trustpilot record is hosted independently, cannot be edited by the vendor, and is the number we use.
A large, real, independent review base. 4.7 across 347 Trustpilot reviews — more than four times Purgo's count and one of the larger records we cover. Oddly, SKO's own homepage cites only 209 of them; its self-citation is stale in the modest direction, which is the opposite of the usual failure.
Sizes stated beside every price. Every vial lists its milligrams on the catalog itself — a transparency point our rubric awards, and one that Purgo's own catalog page fails. It is what makes the honest price comparison below possible at all.
An accountable shipping promise. 24-hour dispatch, with a stated self-penalty — 50% off your next order — if missed. Most vendors promise speed; few attach a cost to failing.
The laboratory has no name. ">99% purity", SPPS synthesis, HPLC and mass spectrometry, a "COA Verified" badge on every product — and no identifiable laboratory anywhere we could find. The right methodology, unverifiable at the source. A certificate from a lab you cannot contact is a document you are trusting the vendor about.
Roughly half the vial catalog was sold out on the day we checked — including BPC-157, GHK-Cu, Tesamorelin, MOTS-c, NAD+ and the Wolverine blend. Worth knowing before planning research around a specific compound.
Both vendors state sizes on these products, so every row is a genuine like-for-like. SKO figures are its sale prices — its list prices are higher. Verified 14 August 2026.

Purgo is cheaper on all six verified pairs — by 23% to 45% before its recurring 20% code, and materially more after it.
SKO Compounds has earned a real reputation — 310 independent reviews at 4.7 is not an accident, and its size-labelled catalog and accountable shipping promise are genuinely good practice. But its testing cannot be traced to a named laboratory, its on-site ratings include reviews for products that have not shipped, and it costs substantially more than better-documented alternatives on every pair we could verify.
Purgo Labs remains our first choice — named labs, per-lot measured content with verify-at-lab links, lower verified prices, and code HEALTH for 20% off every order. Amino Club second.

Third-party rating as read 24 September 2026: 4.8 (535 reviews).
The testing laboratory is not named anywhere we could find, so testing claims cannot be looked up. Pre-order 'Research Sprays' displayed star ratings and review counts before their stated ship date — reviews cannot precede shipment, and on-site review counts are self-hosted and unverifiable. Roughly 15 of ~34 vial products were sold out on the day checked.

It is a real, operating vendor with one of the larger independent review bases we have checked — 4.7 across 347 Trustpilot reviews as of August 2026, more than four times Purgo Labs' count. It states >99% purity with HPLC and mass-spec testing and shows a COA badge on every product. Two findings temper that: the testing laboratory is never named, and its pre-order products display review counts before they have shipped — both covered below.
On the day we checked, SKO's homepage listed five 'Research Spray' products marked pre-order, shipping 22 August 2026 — each already displaying a star rating and a review count, for example a NAD spray at 4.9 from 186 reviews. Reviews cannot precede shipment. We are not asserting an explanation; the observation is checkable on their own homepage, and it means SKO's on-site product ratings should not be relied on. Its Trustpilot record is a separate, independently hosted matter and remains genuine.
Unknown. The site states independent third-party laboratory analysis with HPLC and mass spectrometry, and every product carries a 'COA Verified' badge, but the laboratory is not named anywhere we could find. As with Northline Labs, the methodology described is the right methodology — and an unnamed lab cannot be contacted, so the claim rests on the vendor's word. Interestingly, its own Trustpilot citation on the homepage (209 reviews) undercounts its current independent record (347), which suggests stale copy rather than inflation on that particular number.
SKO states sizes on every product, which allows real comparisons — and Purgo is cheaper on every verified pair, usually by 30–45% even against SKO's sale prices. Ipamorelin 10mg: $79.99 vs $54.99. BPC-157 10mg: $69.99 vs $44.99. GHK-Cu 50mg: $54.99 vs $29.99. Tesamorelin 10mg: $114.99 vs $69.99. Purgo's recurring 20% code widens all of those further. SKO's list prices before sale are higher still. Verified 6 August 2026; several SKO items were sold out when checked.
Three things genuinely. The 347-review Trustpilot base at 4.7 is a substantial, real track record. Sizes are stated beside every price — a transparency point many vendors, including Purgo's own catalog page, fail. And it backs a 24-hour dispatch guarantee with a stated penalty on itself (50% off your next order if missed), which is a more accountable shipping promise than most in the category.
Purgo Labs first: named laboratories (SteriGenix, Freedom Diagnostics) with per-lot measured net content and verify-at-lab links, cheaper on every verified pair above, and code HEALTH for 20% off every order. Amino Club second. SKO's review base is bigger than both — if it named its lab and its on-site ratings reconciled with reality, this ranking would get closer.
