What are peptides?

Peptides are short chains of amino acids, the building blocks that make up proteins in the body. They help support important functions like muscle growth, recovery, metabolism, and keeping skin healthy.

What are the common uses?

Therapeutics, including some approved drugs, along with research, skincare featuring collagen-stimulating peptides, and performance or recovery applications.

Are peptides safe?

Generally, yes. Peptides are short chains of amino acids—the same building blocks found in your body's natural proteins. Because they are "biologically native," the body typically recognizes and processes them efficiently. However, safety is highly dependent on the quality of the peptide and whether it is being used under professional guidance.

How should peptides be stored after delivery?

After delivery:


• Keep the vial in a cool, dark environment
A drawer, cabinet, or storage box away from heat and sunlight is ideal.
• Avoid moisture and temperature swings
Consistent conditions help maintain stability.
• Refrigeration is commonly used once reconstituted
After a peptide is mixed with a diluent in a research setting, it’s usually kept in a refrigerator to maintain stability.

How does NordicPure ensure the quality of its peptides?

NordicPure Peptides guarantees top-notch quality with thorough third-party testing for purity, identity, and concentration. Each batch receives a Certificate of Analysis (CoA), showing our dedication to delivering high-purity research peptides. This COA is available upon request.

What are the most studied peptides?

BPC‑157 supports healing for the gut and tendons, GHK‑Cu promotes healthier skin and hair while offering-aging benefits, CJC‑1295 helps stimulate growth hormone release, Ipamorelin also boosts growth hormone and works well with CJC‑1295, and Semaglutide is used for metabolic research.

How do you reconstitute peptides?

Reconstituting peptides means dissolving lyophilized (freeze‑dried) peptide powder into a sterile liquid (usually bacteriostatic or sterile water) using aseptic technique; the exact diluent, volume, and handling depend on the peptide’s chemistry. 

Step-by-step peptide reconstitution


1. Prepare workspace and materials
• Wash your hands thoroughly.
• Clean and organize your workspace.
• Gather the peptide vial, sterile/bacteriostatic water, alcohol swabs, and a sterile syringe with needle.


2. Sanitize vial stoppers
• Wipe the rubber stoppers of both the peptide vial and the water vial with an alcohol swab.
• Allow them to air dry for a few seconds.


3. Draw the diluent
• Attach the needle securely to the syringe.
• Draw the desired volume of sterile/bacteriostatic water into the syringe (for example, 1–2 ml, depending on your target concentration).


4. Inject water into the peptide vial
• Insert the needle into the peptide vial at a slight angle to reduce foaming and bubbles.
• Slowly inject the water so it runs down the inner wall of the vial rather than directly onto the powder.


5. Dissolve the peptide
• Gently swirl or roll the vial between your fingers until all visible particles are dissolved.
• Do not shake vigorously, as this may damage the peptide structure.

 

6. Label and store
• Clearly label the vial with the peptide name, concentration, and date of reconstitution.
• Store the reconstituted peptide in a refrigerator as per product-specific guidance and stability data.

How do you calculate peptide doses?

Why are peptides sold in a "freeze-dried" powder form?

This process is called lyophilization. In powder form, the molecular structure of the peptide is much more stable and resistant to heat and light during shipping. Once a peptide is turned into a liquid (reconstituted), it begins to degrade much faster.

How long do peptides last once they are reconstituted (liquid)?

Once mixed with a solvent (like bacteriostatic water), peptides are much more fragile. They should be stored in the refrigerator at 2-8°C and typically remain potent for 2 to 4 weeks

What is the best solvent for reconstituting peptides?

For most research purposes, Bacteriostatic Water (sterile water with 0.9% benzyl alcohol) is the standard. The alcohol acts as a preservative, inhibiting the growth of bacteria.
