Peptide FAQs

1. What is a peptide?

Peptides are short chains of amino acids that act as the building blocks of proteins. They are widely used in scientific research, biotechnology, and medical studies.

2. How should I store my peptide when I receive it?

For optimal stability:

Lyophilized (dry) peptides: Store in a cool, dry place, preferably in a freezer (-20°C).
Reconstituted peptides: Keep refrigerated at 2-8°C and use within a short period to maintain integrity.

3. What form do you sell your peptides in?

All our peptides are lyophilized (freeze-dried) powders to ensure maximum stability and shelf life.

4. How can I reconstitute my peptides?

Peptides can be reconstituted with sterile bacteriostatic water, acetic acid, or saline solution, depending on their solubility. Refer to each product’s description for specific recommendations.

5. Why does the peptide look cloudy when I mix it?

Some peptides have low solubility in water, which can cause cloudiness. Try gently swirling the solution or using a suitable solvent as recommended.

6. Can I send your products to be tested?

Absolutely! We stand by our quality and encourage independent verification. Our peptides undergo rigorous HPLC and Mass Spectrometry testing for purity and accuracy.

7. Why does this vial contain less than my previous order?

While we precisely measure each vial’s content, density and consistency can vary slightly between batches. However, rest assured that all vials contain the stated quantity.

8. Why do peptides differ in appearance?

Natural variations in peptide composition can result in differences in texture, color, or crystallization. This does not affect purity or efficacy.

9. What can I use your peptide products for?

Our peptides are strictly for research purposes only. They are not intended for human consumption, medical treatment, or diagnostic use.

10. Do you sell other products that don’t appear on your website?
