Peptide vendors in South Africa, scored on documentation — not marketing.
We check what each vendor actually publishes — lab reports, courier SLAs, refund terms, business registration — against the same criteria, every time. No paid placements.

7.6 / 10Of the thirteen vendors we've fully verified so far, LEOLABS is the one our editorial team recommends first. It's the only vendor in our set that names an actual third-party testing lab and links a specific, individually numbered report for each product — not just a "third-party tested" claim with nothing behind it.
We could not independently confirm the lab reports beyond LEOLABS's own links (the lab's verification portal blocks automated checks) — see how we rate for exactly what "verified" does and doesn't mean here.

Scores run low across the board — this is a young, thinly-documented market, not a curve we grade on. See the full comparison for all 13 vendors, plus who we looked at but didn't rank.

Mechanism, clinical status and regulatory reality for the compounds people ask about most.
Semaglutide
FDA-approved as Ozempic/Wegovy — mechanism, approvals, what "research-grade" means outside a prescription.
Tirzepatide
FDA-approved as Mounjaro/Zepbound — how the dual mechanism differs from semaglutide.
Retatrutide
Still in Phase 3 trials, not approved anywhere — what the published trial data actually shows.
Frequently asked questions
Common questions from buyers comparing vendors in South Africa.
Is it legal to buy peptides for personal use in South Africa?
These products are sold as "research chemicals," not as SAHPRA-registered medicines for human use. SAHPRA has publicly stated that unregistered peptides — including BPC-157, TB-500 and CJC-1295 — lack market approval and has warned against their sale and use. Buying them for personal use sits in a legal grey area rather than a clearly regulated one. This isn't legal advice — see our regulatory note in How We Rate.
How can I check whether a peptide is actually what it claims to be?
Look for a Certificate of Analysis (COA) from an independent third-party lab — not just an in-house test — that names the lab, gives a batch or task number you can look up, and reports purity and identity (typically via HPLC or mass spec). A vendor that only says "third-party tested" with no link, lab name or report number hasn't actually shown you anything.
What should I look for when choosing a vendor?
The things that are hardest to fake: named, checkable lab reports per product; a published courier and delivery SLA; disclosed business registration and contact details; a clear refund/replacement policy; and consistent pricing. We score every vendor we review against these same criteria — see individual vendor reviews for specifics.
How are peptides usually delivered and stored?
Most vendors we've reviewed ship via standard courier, typically 1–5 business days, with the product usually sent lyophilised (freeze-dried), which is more stable at room temperature than reconstituted liquid. Once reconstituted, peptides generally need refrigeration and have a limited shelf life — follow the specific vendor's or product's own documentation.
What payment methods do vendors typically accept?
EFT/bank transfer is the most common across the vendors we've reviewed; some also accept card payments or a local gateway such as PayFast. A vendor that accepts only manual EFT with no other verifiable payment trail is worth extra scrutiny.
How do vendors actually differ from each other?
Mainly in documentation quality, product range, delivery speed and pricing — not in "purity" claims, which are cheap to make and hard to verify without a named lab report. Two vendors selling the same peptide can differ a lot in whether you can actually check what you're getting.
How does Peptides.SA calculate its ratings?
We score every vendor against eight fixed criteria — documentation, transparency, delivery, pricing, assortment, refunds, reputation and support — applied the same way regardless of whether a vendor advertises with us. We don't accept payment for placement or score. Full breakdown on the How We Rate page.
Can you tell me how much to take or how to use these products?
No — we don't provide dosing, administration or usage guidance, and this site isn't a substitute for medical advice. These are unregistered research chemicals, not prescribed medicines; anything about using them on yourself should go through a qualified medical professional, not a vendor review site.
