Research Peptides in Sabah & Sarawak
KYIN Peptides ships research-grade peptides directly to East Malaysia — Sabah and Sarawak — with free delivery, no minimum order amount, and typical arrival within 3–5 working days.
Our peptides are relatively stable at room temperature and don't require cold-chain shipping, so the longer trip across the South China Sea doesn't compromise your order.
The Research Community in Sabah & Sarawak
Separated from Peninsular Malaysia by the South China Sea, Sabah and Sarawak have their own research institutions — Universiti Malaysia Sabah (UMS) in Kota Kinabalu and Universiti Malaysia Sarawak (UNIMAS) in Kuching — with particular strength in tropical biodiversity and marine science. That same geographic separation is why East Malaysia orders run on a longer 3–5 working day delivery window rather than the 1–3 days we offer across Peninsular Malaysia.
Delivery to Sabah & Sarawak
East Malaysia orders typically arrive within 3–5 working days of being placed. Delivery is free on every order, with no minimum order amount required. Next-day express delivery is currently only available for West Malaysia orders. These timeframes are estimates and are not guaranteed, as delivery can be affected by factors outside our control.
Payment Options
We accept Touch 'n Go, cryptocurrency, Revolut, and Wise for orders within Malaysia, including Sabah and Sarawak. Message us on WhatsApp to confirm details before placing your order.

East Malaysia delivery questions
Does KYIN Peptides deliver to Sabah and Sarawak?
Yes — we deliver to both Sabah and Sarawak (East Malaysia), with free delivery and no minimum order amount, the same as the rest of Malaysia.
How long does delivery to East Malaysia take?
East Malaysia orders typically arrive within 3–5 working days. Next-day express delivery is currently only available for West Malaysia orders. These are estimates and not guaranteed, as delivery can be affected by factors outside our control.
Do research peptides need cold storage during the longer delivery to East Malaysia?
No. The lyophilized (freeze-dried) peptides we ship are relatively stable at room temperature for the duration of standard delivery, so no cold-chain shipping is required — see our guide to storing peptides in a tropical climate for what to do once your order arrives.
