Quick answer
Zurich Biotech ships lyophilized research peptides to Medan and the surrounding Deli Serdang and Binjai areas, typically within one to two business days. Medan sits on North Sumatra's main cold chain corridor: cargo moves through Kualanamu International Airport, which runs dedicated 0 to 7°C and -25 to 0°C cold rooms, or through the Port of Belawan, Indonesia's busiest seaport outside Java. BPOM Regulation No. 30 of 2022 (as amended by Regulation No. 12 of 2024) governs research-use imports of unregistered pharmaceuticals through the Special Access Scheme, and that framework applies to research peptides received anywhere in Indonesia, including Medan.
BPOM and the regulatory framework for research imports
BPOM (Badan Pengawas Obat dan Makanan) is Indonesia's national authority for drug and food oversight. Any pharmaceutical product without a domestic Marketing Authorization must enter through a licensed channel. For research purposes, that channel is the Special Access Scheme (SAS), which covers research, clinical development, and other non-commercial scientific uses.
Research peptides are not classified as narcotics or psychotropics under Indonesian law, so they move through the standard SAS route rather than a more restrictive pathway. BPOM Regulation No. 12 of 2024 amended the original 2022 SAS rule and shortened the administrative turnaround for research-use import approvals.
For a researcher receiving a shipment at a Medan address, the SAS authorization sits with the importing entity, not the individual. The researcher takes delivery of a research-use compound already covered by that authorization. Orders ship with a Certificate of Analysis; the COA guide covers what to check on arrival.
Shipping to Medan and North Sumatra
Medan is North Sumatra's provincial capital and the largest city outside Java, which gives it more pharmaceutical logistics infrastructure than any other city on the island. The Port of Belawan, about 24 kilometers north of the city center on the Strait of Malacca, is Indonesia's busiest seaport outside Java and handles container, general, and reefer cargo for the wider Sumatra region. Kualanamu International Airport, roughly 39 kilometers southeast of the city, runs a dedicated cargo terminal with shipment tracking and two certified cold rooms, one at 0 to 7°C and one at -25 to 0°C, for pharmaceutical and perishable freight.
Orders reach central Medan districts, including Medan Petisah, Medan Baru, Medan Polonia, Medan Selayang, and Medan Johor, within one business day of dispatch. Surrounding Deli Serdang towns, including Lubuk Pakam and Tanjung Morawa, plus neighboring Binjai, receive orders within one to two business days. Apartment buildings, clinic addresses, and university research offices across the metro area all use standard courier procedures.
Climate and storage requirements in Medan
Medan sits close to the equator and carries a tropical rainforest classification under the Koppen system. Average temperatures run 26 to 27°C year round, with highs regularly reaching into the low 30s and lows rarely dropping below 23°C. Relative humidity stays high all year, from around 85% in February to close to 90% in November, and annual rainfall totals about 3,085 mm across nearly 300 rainy days.
Lyophilized peptides pick up ambient moisture once a vial is opened or a seal is compromised under these conditions. A 2015 stability study of a lyophilized peptide hormone formulation in the International Journal of Pharmaceutics (Srinivasan et al., Int J Pharm 2015) found particulate formation in reconstituted samples after storage under elevated temperature and humidity, detected using dynamic light scattering. Medan's ambient conditions sit close to or above the accelerated-storage parameters that study used for most of the year.
Lyophilized vials should go into a freezer at -20°C or colder as soon as they arrive. A multi-laboratory consensus on peptide handling for mass spectrometry assays, published in Clinical Chemistry (Hoofnagle et al., Clin Chem 2016), states that long-term peptide storage beyond six months works best at -20 to -80°C, and that repeated freeze-thaw cycles should be avoided. A household or lab freezer at -18°C meets that threshold for most compounds over a research window of six to twelve months.
Reconstituted peptide belongs in a refrigerator at 2 to 8°C and should not sit at room temperature between uses. Medan's power grid is generally stable within the city core, though outer Deli Serdang areas see more frequent short outages than central districts. A small UPS on the storage freezer covers brief interruptions without needing generator backup. The full protocol on freeze-thaw limits, desiccant use, and compound-specific handling is in the lyophilized peptide storage guide.
Research environment in Medan
Universitas Sumatera Utara (USU) runs North Sumatra's largest pharmacy and biomedical research program. Its Faculty of Pharmacy holds four accredited study programs, two rated Excellent, and organizes research into four groups: pharmaceutical biology, pharmaceutical technology, pharmaceutical chemistry, and pharmacology and clinical pharmacy. Much of its published work centers on natural-product drug development, with recurring output in antidiabetic, anticancer, and immunomodulator research, supported by nine laboratories and an on-site animal facility.
RSUP H. Adam Malik, a Class A national referral hospital in Medan, functions as the clinical research anchor for USU's Faculty of Medicine, in a pairing similar to FKUI and Cipto Mangunkusumo in Jakarta. Its Department of Cardiology and Vascular Medicine holds joint appointments with USU and has produced clinical publications through that partnership. The hospital also hosts research placements for USU medical students, extending the university's research reach into direct patient-facing work.
Research peptides ordered in Medan
Tissue repair compounds account for the largest share of orders shipped to Medan. BPC-157 and TB-500 together make up the bulk of vials sent to the city, a pattern that lines up with USU's own research focus on wound healing and regenerative mechanisms. Metabolic peptides, including retatrutide and semaglutide research protocols, make up a smaller but growing share of orders, tracking the broader national rise in GLP-1 and related receptor research.
For reconstitution and dosing calculations on any compound shipped to Medan, the peptide dosing calculator handles concentration math and U-100 syringe conversions for standard vial strengths.
