Research Peptides SA Review
4.3 / 10Ranked #5 of 13 verified vendors
Research Peptides SA, or RPSA (researchpeptides.co.za), claims the longest track record of any vendor we've checked — but it turns out to be the same legal entity as another vendor in this list, undisclosed to shoppers on either site.
What we verified directly
- "Trading since 2006." The site states: "Since 2006, we have been consistently selling peptides online... for the past 20 years." This is the vendor's own claim, not third-party audited, but it's their own wording, not a paraphrase from a competitor.
- In-house testing. "Purity levels of 97% and above, which are thoroughly tested and certified in-house," with in-house testing for "heavy metals, toxins and consistency."
- COA on request. "COA documents can be requested for items as needed. These are renewed bi-annually."
- Shipping & payment. Postnet or door-to-door courier; EFT, Visa and Mastercard via PayFlex.
Undisclosed common ownership: Buy Peptides SA's own footer identifies itself as "Research Peptides South Africa (PTY) LTD" — meaning these two "competing" storefronts are run by the same legal entity. Neither site discloses this to shoppers. We treat this as a real transparency issue, not a technicality, and score both vendors down for it.
Where it loses points
- No third-party testing. All quality testing described is in-house; no external lab is named anywhere.
- No registration number or address published on the pages we checked.
- Undisclosed sibling brand (see above) — a real transparency deduction, not a hedge.
Score breakdown
| Criterion | Weight | Score |
|---|---|---|
| Documentation (named lab, batch refs) | 25% | 10/25 |
| Business transparency | 15% | 4/15 |
| Shipping & delivery | 15% | 9/15 |
| Pricing transparency | 10% | 4/10 |

Bottom line
A claimed two-decade history and a real (if in-house) testing process count for something — but running an undisclosed sibling storefront is the kind of thing our transparency criterion exists to catch, and it caps how high this vendor can rank regardless of tenure.
Regulatory note: the peptides Research Peptides SA sells are not SAHPRA-registered medicines. This review describes what the vendor publishes about its own operations — it is not medical advice and not an endorsement of using these products.
