Reference peptides for Penang research groups

How shipments reach Penang

Batch numbers on the vial cap should match the certificate exactly — if they do not, stop and ask us before opening anything. From confirmation to dispatch is normally one to three working days. The delivery window into Penang is 5–18 business days from the moment tracking goes active, and that figure is the same one we give every customer in every country. The route uses a tracked delivery service; the route and carrier depend on the dispatch hub, and import rules for research reference material in Malaysia remain the buyer's responsibility to confirm before ordering.

A laboratory on the edge of Penang is served on the same route as one in the middle. We answer messages from Penang during European working hours, and usually the same day. Collection points in Johor Bahru, Kota Kinabalu, Kuching, Ipoh and Malacca are handled identically. We answer messages from Penang during European working hours, and usually the same day. Tracking is issued at dispatch and stays live to the door; we stay reachable on WhatsApp for the duration of transit.

What the batch paperwork actually shows

Repeat customers in Penang tend to settle on three or four compounds and stay with the same lots for consistency. Each production batch is tested independently by high-performance liquid chromatography for purity and by mass spectrometry for identity. The result is published on the certificate as a chromatogram, not as a headline percentage with nothing behind it. Penang buyers can request the certificate for a specific batch number before any payment is arranged. If you are comparing suppliers from Penang, ask each of them for the raw chromatogram rather than a summary sheet.

If an archive copy is needed later, it is available. Where work is split between Penang and another site, matched batches remove a common source of unexplained variance.

Regulatory notes for Malaysia

Everything in the catalogue is supplied as a research reference standard for in-vitro laboratory use. Batch numbers on the vial cap should match the certificate exactly — if they do not, stop and ask us before opening anything. It is not a medicine, not for human or veterinary administration, and not sold for therapeutic, diagnostic or cosmetic use. Local research-chemical rules vary; the buyer in Malaysia is responsible for checking them. Import rules for research reference material in Malaysia remain the buyer's responsibility to confirm before ordering.
