Frequently Asked Questions

Peptides are created by linking amino acids with peptide bonds. This bond forms when one amino acid’s amino group connects with another’s carboxyl group, releasing water.

In the lab, peptides are usually made through solid-phase peptide synthesis:

1. Start: The first amino acid attaches to a solid support with a protected amino group.
2. Add Amino Acids: The protecting group is removed, and the next amino acid is added to form a bond.
3. Repeat: This process continues until the desired peptide is complete.
4. Finish: The final peptide is detached from the solid support and any remaining protecting groups are removed.

This method allows scientists to create peptides with specific amino acid sequences for research and development.

Yes, all our peptides contain trace amounts of mannitol. Mannitol is a sugar alcohol that helps:

• Stability: Prevents peptide aggregation and maintains structure.
• Solubility: Enhances peptide solubility in water or saline.
• Moisture Protection: Absorbs moisture to protect peptides from degradation.
• Handling: Improves the flow properties of peptide powders for easy processing.

Mannitol ensures you can see the peptide product in the vial.

Peptides absorb moisture, so let them warm to room temperature before opening. Follow these steps for handling:

1. Weigh Quickly: In a clean environment, weigh only what you need.
2. Reseal Tightly: Close the container after use.
3. Store Properly: Keep unused peptides at -20°C or lower in a sealed container with a desiccant.

Proper storage reduces bacterial degradation and oxidation, extending shelf life. When dissolving peptides, use recommended solvents and sonication if needed. Sterilized water is preferred, but buffers can be used based on peptide properties.

Important: Peptides in solution are less stable than in freeze-dried form. If storing in solution, keep at -20°C with sterile buffers at pH 5-6.

Our Parcel Follow-up Policy

We understand the importance of timely deliveries. Please allow up to seven days for your parcel to arrive before contacting us. This helps accommodate any minor shipping delays.

International Deliveries and Customs

International deliveries may be held in customs, causing delays beyond our control. If customs request additional documents, we are here to assist, but resolution time depends on customs authorities.

Shipping Process

Our peptides are shipped in their lyophilized (freeze-dried) state to ensure stability. We package them carefully to protect against environmental factors.

Protection from Sunlight

Our packaging shields peptides from direct sunlight, preserving their condition during transit.

Post-Delivery Handling and Storage

Upon receipt, handle peptides properly. Once reconstituted, store them in the refrigerator to maintain quality and effectiveness.

Thank you for your order and payment. We do not individually confirm payments to avoid processing delays. Our dispatch team will process your order promptly once the payment is registered. You will receive an email confirmation and tracking information later today. Thank you for your understanding and support.

We do not offer blended peptides like ipamorelin and CJC MOD GRF. Blends often have inappropriate ratios for most research applications, making exact microgram usage difficult to determine. We recommend purchasing peptides separately to ensure accurate and reliable research results. For example, you can mix 100mcg of Peptide A and 100mcg of Peptide B in the same syringe. This ensures precise dosage and integrity in your research.

Combining two peptides into a single vial is not necessarily cheaper. Purchasing separately maintains accuracy and effectiveness.
