Pure Labs (Pure Performance Labs (Pty) Ltd) Review
Rank #1 of 10
purelabs.co.za vendor site ↗ (reference only, not an endorsement)
Evidence confidence: Medium. · Last verified: 2026-09-22
The most transparent vendor on paper in this edition — named laboratory, specific COA reference and a registered company name — but with no independently checkable public reputation record found.
What we verified
We independently confirmed that purelabs.co.za publishes a Dowerglen, Edenvale (Gauteng) address, a formal company name (“Pure Performance Labs (Pty) Ltd”), a stated CIPC-style registration number, and dedicated shipping, returns, privacy and terms pages [20][21]. We confirmed Janoshik Analytical is a real, independent testing laboratory used broadly across the research-peptide market.
What the vendor claims
Pure Labs' retatrutide product page claims 99.8% verified purity, third-party lab testing, and a downloadable Certificate of Analysis referencing report code “222437-Sample_2_9HG1CCB2W783.” Retatrutide is listed in 10mg, 20mg, 30mg and 40mg vials and as pre-filled pens, priced R899–R1,999. The site states products are intended for research and laboratory use only and have not been evaluated by SAHPRA [20].
Testing & documentation
The retatrutide product page names Janoshik Analytical as the testing laboratory and cites a specific COA report code. This is a more specific, checkable-format disclosure than most vendors in this edition provide. We did not independently open or verify that report against Janoshik's own lookup tool, so we can confirm the claim is published in specific, checkable form — not that the underlying result is genuine.
Business transparency
Pure Labs publishes a specific suburb-level address, a formal registered company name, and a company registration number in a CIPC-consistent format, alongside an email address and a WhatsApp-only mobile number with stated business hours [21]. This is the most complete business-identity disclosure found among the vendors reviewed in this edition, though none of it was cross-checked by this review against the CIPC companies register itself.
Shipping
A dedicated Shipping Policy page exists at purelabs.co.za/shipping-policy/. We confirmed the page exists; we did not extract or verify its specific courier or delivery-timeframe commitments in this review.
Refunds & returns
A dedicated Return Policy page exists at purelabs.co.za/returns-policy/. We confirmed the page exists; its full terms were not reviewed in detail here.
Website & policies
Separate Privacy Policy and Terms and Conditions pages are published at purelabs.co.za/privacy-policy/ and purelabs.co.za/terms-and-conditions/ respectively, alongside a clear statement that products are intended for research and laboratory use only, have not been evaluated by SAHPRA, and are not intended to diagnose, treat, cure or prevent any disease.
Public reputation
We could not locate a dedicated Hellopeter, Trustpilot or Google review page specifically for “purelabs.co.za” or “Pure Performance Labs”; a search for “purelabs.co.za reviews” returned results for an unrelated business (“PureSip”). We are treating this as an absence of accessible public reputation evidence, not as a negative signal in itself.
Regulatory & research-use context
Pure Labs explicitly states its products have not been evaluated by SAHPRA and are intended for research and laboratory use only, consistent with retatrutide's investigational status generally (see our retatrutide research overview). No SAHPRA registration or approval is claimed.
Strengths & limitations
Strengths
- Publishes a specific trading address, a formal registered company name and a CIPC-style registration number in checkable form
- Names a specific third-party testing laboratory (Janoshik Analytical) and references a specific Certificate of Analysis identifier on its retatrutide product page
- Dedicated, separately published shipping, returns, privacy and terms pages exist for every core policy area
- A clear, prominent research-use-only and “not evaluated by SAHPRA” disclaimer
Limitations
- No independent public reputation signal (Hellopeter, Trustpilot, Google) could be located for this vendor at all
- Neither the company registration number nor the specific Certificate of Analysis identifier was independently cross-checked against CIPC or against Janoshik's own verification tool
- Shipping and refund policy pages were confirmed to exist but their specific courier and timeframe detail was not extracted in this review
Evidence confidence
Medium. Pure Labs publishes a specific address, a formal company name and registration number, and a named testing laboratory with a report identifier — all in checkable form, though none of it was cross-checked by this review against CIPC or against the laboratory's own database. No independent public reputation signal (review platform) could be located for this vendor.
Methodology score breakdown
| Criterion | Why this score | Points |
|---|---|---|
| Business Transparency | A specific address, a formal registered company name (Pure Performance Labs (Pty) Ltd) and a CIPC-style registration number are all published in checkable form. | |
| Testing & Documentation Disclosure | Names Janoshik Analytical as the testing laboratory and references a specific Certificate of Analysis identifier on the retatrutide product page. | |
| Independent Verifiability of Testing Claims | The laboratory and identifier are specific and plausible, but this review did not independently confirm the COA against Janoshik's own database. | |
| Policy Completeness (Shipping, Refunds, Terms, Privacy) | Dedicated shipping, returns, privacy and terms pages all exist, but the depth of the shipping and returns pages specifically was not confirmed. | |
| Research-Use & Regulatory Framing Clarity | A clear research-and-laboratory-use-only disclaimer states products are not evaluated by SAHPRA and not intended to diagnose, treat, cure or prevent disease. | |
| Public Reputation Signals | No dedicated review-platform page (Hellopeter, Trustpilot, Google) could be located for this vendor; a search for reviews returned an unrelated business. | |
| Website & Policy Reliability | The site functioned normally with no reported inconsistencies or deceptive patterns. | |
| Source Accessibility for Independent Review | The pages reviewed were reasonably accessible with no blocking encountered. | |
| Total | 83 / 100 | |

Editorial conclusion
On paper, Pure Labs discloses more specific, checkable business and testing detail than any other vendor in this edition — a named lab, a specific COA reference, and a registered company name and number — which is why it ties for the highest score under our frozen methodology (83/100, tied for rank #1 of 10 by score with LEOLABS; see How We Rate). What remains uncertain is everything this review's evidence-gathering process cannot reach: whether the COA and registration number are genuine, and how the business behaves in practice, since no independent public reputation record could be found at all. That absence of any third-party track record — positive or negative — is itself the main limitation here, and is why Pure Labs is not our Editor's Pick despite tying on score: our LEOLABS designation specifically weighs a large, checkable, currently-active public reputation record, which Pure Labs currently lacks. From a transparency standpoint, Pure Labs' published specifics make it a reasonable starting point for further reader research, provided that research includes independently checking the claims this review could not reach.
