Frequently Asked Questions

Answers about our products, pricing, shipping, quality standards, and research-use compliance.

Product Information

What are peptides?

Peptides are short chains of amino acids, the building blocks of proteins. They play key roles in various biological functions and are commonly used in research studies.

How do peptides differ from proteins?

Peptides are smaller molecules, usually consisting of 2–50 amino acids, whereas proteins are larger, complex structures made up of one or more long chains of amino acids.

Are your peptides synthetic or naturally derived?

All Peplogix peptides are synthetically produced using advanced techniques to ensure high purity and consistency.

What is the purity level of your peptides?

Peplogix peptides have a purity of ≥99%, ensuring high-quality standards for research and application purposes.

How do you verify the quality and purity of your peptides?

Peplogix uses rigorous analytical techniques, including HPLC (High-Performance Liquid Chromatography) and mass spectrometry, to confirm the identity and purity of each peptide.

Do you provide Certificates of Analysis (CoA) for your peptides?

Yes, each peptide comes with a Certificate of Analysis (CoA) verifying its purity, composition, and quality.

How should I store lyophilized peptides?

Lyophilized peptides should be stored in a cool, dry place, ideally at –20°C, and protected from moisture and light to maintain stability.

How long do reconstituted peptides remain stable?

Reconstituted peptides are typically stable for 1–4 weeks when stored in a refrigerator at 2–8°C. Stability varies depending on the peptide type.

Do peptides degrade over time?

Yes, peptides can degrade due to environmental factors such as temperature, light, and moisture. Proper storage maximizes shelf life.

Do your peptides contain additives or preservatives?

No, Peplogix peptides are provided in pure form without any unnecessary additives or preservatives.

What is the difference between lyophilized and liquid peptides?

Lyophilized peptides are freeze-dried for stability and long-term storage, while liquid peptides are pre-dissolved and ready for immediate use but typically have a shorter shelf life.

Can I request a specific peptide that is not listed on your website?

Yes, Peplogix can accommodate custom peptide requests based on research.

Do you provide peptide blends, or must they be purchased separately?

Peplogix offers both individual peptides and custom blends, depending on your requirements.

What is Biofermented NAD+?

Biofermented NAD+ (Nicotinamide Adenine Dinucleotide) naturally has a slight yellow tint, which is a normal characteristic of a high-quality, concentrated formulation — not a sign of contamination or degradation. Unlike heavily processed white powders, premium biofermented NAD+ may appear yellow due to its natural composition, stability, and trace NADH content. This coloration is often associated with improved purity, potency, and product stability. Biofermented NAD+ is valued for supporting cellular energy production, healthy aging, cognitive function, metabolism, and overall wellness.
