We ship research peptides across Canada, including Ontario, Quebec, British Columbia, Alberta, Manitoba, Saskatchewan, Nova Scotia, New Brunswick, Newfoundland and Labrador, Prince Edward Island, Yukon, Northwest Territories, and Nunavut.
Melanotan II is a synthetic research peptide analog of alpha-melanocyte-stimulating hormone, commonly studied for its interaction with melanocortin receptor signaling pathways. In laboratory settings, it is examined for its potential role in melanin pathway research, pigmentation response models, and receptor-binding activity.
In research environments, Melanotan II is often studied for how melanocortin analogs may influence biological systems involved in pigment regulation, cellular signaling, and melanocyte-related pathway activity. Its research interest comes from its structural stability, receptor affinity, and relevance in controlled studies focused on melanocortin system behavior.
At Polar Peptides, Melanotan II is supplied strictly for research use only and is intended for qualified laboratory, analytical, or educational research applications. For researchers looking for Melanotan II in Canada, Polar Peptides provides a reliable source of research peptides with a focus on quality, consistency, and transparent product information.

Most standard lyophilized research vials are commonly prepared using 2mL of bacteriostatic water unless otherwise specified directly on the product page or vial label.
For best handling, slowly add the bacteriostatic water down the inside wall of the vial rather than directly onto the powder. This helps reduce unnecessary agitation and supports product integrity during laboratory use.
After adding bacteriostatic water, gently swirl or roll the vial until the lyophilized powder has fully dissolved. Avoid aggressive shaking, as excessive agitation may affect product stability.
Prepared vials should typically be stored refrigerated between 2-8°C for best stability. Lyophilized vials that have not yet been prepared should be stored in a cool, dry environment away from direct sunlight, moisture, and excessive heat.
Proper storage and handling procedures are important for maintaining product purity, consistency, and reliability throughout laboratory applications.

All products sold by Polar Peptides are intended strictly for research use only and are not intended for human consumption, medical use, diagnostic use, or any other unauthorized use.
Lyophilized research products should be stored in a cool, dry environment prior to preparation to help maintain long-term stability and purity.
Refrigeration is recommended for most products after opening. Prepared vials should remain refrigerated between 2-8°C and protected from repeated temperature changes.
Exposure to excessive moisture, heat, direct sunlight, or frequent freeze-thaw cycles may negatively impact product stability during laboratory applications.
Polar Peptides supplies high-purity research products, peptide blends, laboratory-use materials, and advanced analytical compounds manufactured with quality, consistency, and secure packaging in mind.
Proper storage and handling procedures are recommended to maintain product integrity, consistency, and analytical reliability throughout laboratory research environments.
What Are Peptides?
Peptides are short chains of amino acids commonly studied in laboratory and analytical research settings. They may be used to evaluate molecular structure, peptide stability, receptor interaction, biological signaling pathways, and compound behavior under controlled research conditions.
Different peptide compounds may be studied across categories such as peptide chemistry, cellular signaling, formulation testing, analytical comparison, compound stability, and protein interaction research.
Polar Peptides provides Canadian research peptides and laboratory-use compounds with a focus on purity, consistency, secure packaging, and fast Canadian fulfillment.
All products are supplied for laboratory research purposes only and should be handled in accordance with proper research standards and applicable regulations.

Vial Specifications
Each vial contains peptides at approximately 104% of the labeled amount, helping support consistency for laboratory research applications.
Products are supplied in lyophilized, freeze-dried powder form. Lyophilization is commonly used to help preserve peptide stability during shipping and storage prior to preparation.
Our standard peptide vials are approximately 16mm in diameter and 38mm in height, with a maximum fill capacity of 3mL.
Peptides requiring preparation may be paired with bacteriostatic water for laboratory use. View bacteriostatic water .
We do not ship products in pre-mixed liquid form. Supplying products in lyophilized powder form helps support stability during transit and storage.
COAs & Lab Reports
Polar Peptides uses quality-control procedures designed to verify peptide purity, identity, and consistency before products are made available.
Testing may include analytical methods such as HPLC and Mass Spectrometry, which are commonly used in peptide quality verification to evaluate purity percentage, molecular identity, and batch consistency.
Certificates of Analysis, also known as COAs, can be provided upon request when available. These reports may include purity data, batch identification, and relevant analytical testing details.
Note: Due to laboratory processing times, batch turnover, supplier timelines, and the number of products offered, COAs may not always be immediately available for every batch.
You can also visit our COA reports page for available documentation.
