Research peptides for cros & contract labs in South Africa
South Africa's contract research and analytical laboratory sector, from the clinical-trial CROs in Gauteng to the analytical labs around Cape Town and Durban, sources research compounds against documentation requirements that a retail supplier rarely meets. This page is written for that procurement conversation.
It covers what we document and what we do not, how lots are traced, how repeat supply works, which compounds and bulk powders are available, and the literature those compounds come from. It is deliberately plain about limits: our certificates are independent Janoshik Analytical HPLC identity and purity reports, and nothing more is claimed. Compounds are supplied for laboratory research only.
What this field's literature looks at
Contract labs meet research peptides as analytes as often as reagents. HPLC purity methods for short peptides, identity confirmation, stability under storage and reconstitution conditions, and degradation profiles in formulation bases are the practical literature, and it is the same literature our certificates rest on. Where a client protocol requires mass spectrometry or endotoxin testing, that is additional work the laboratory performs; we do not hold or claim those data.
The compound literatures themselves span repair (BPC-157, thymosin β4), copper-peptide biology (GHK-Cu, with bulk powder available for method development), mitochondrial function (SS-31, MOTS-c), neuropeptides (Semax, Selank) and cosmetic peptides (acetyl octapeptide-3). A CRO supporting a client study in any of these fields can source the compound and the primary reading from the same product page.

View product and certificate →Ordering in South Africa
CROs and analytical labs in Gauteng are usually next business day from our Johannesburg hub with The Courier Guy; Cape Town and Durban are one to two. Weekday orders paid before noon dispatch the same afternoon in sealed, labelled research packaging. Bulk powders and multi-vial orders clear the R2,500 free-shipping line. Lot references appear on the invoice and the certificate link on each product page, and storage guidance is published per compound.
Questions before ordering: WhatsApp 076 680 0306 or 072 926 7667. Delivery detail for your city: research peptides in Johannesburg.
Questions cros & contract labs ask
What documentation ships with each lot?
An independent Janoshik Analytical certificate stating compound identity and HPLC purity, referenced to the lot. Certificates not yet published are supplied on request.
Do you provide mass-spectrometry or endotoxin data?
No. We hold HPLC identity and purity reports only and say so. Additional testing is the laboratory's own.
Can you supply the same lot across repeat orders?
Where stock from that lot remains, yes. Message us with the lot reference before ordering.
Can you invoice a company account?
Yes. Place the order and message us with the company details and purchase-order reference.
