Open CalculatorFrequently Asked Questions
Find answers to common questions about our research peptides and services.
What does 'Purity Exceeds 99%' mean?
Our peptides undergo rigorous quality control testing to ensure purity exceeds 99%. This means the product contains minimal impurities and is suitable for precise research applications. Each batch is independently verified.
Are these products for human consumption?
No. All NEXGN LAB products are labeled 'For Research Use Only' and are not intended for human consumption. They are designed exclusively for laboratory and research applications. Purchase requires appropriate institutional credentials and licensing.
What storage conditions are required?
Most peptides should be stored at 36-46°F (2-8°C) to maintain stability and potency. Protect from light and do not freeze. Specific storage requirements are provided with each product. Reconstituted solutions have a limited shelf life and should be stored according to guidelines.
How do I use the Protocol Calculator?
The Protocol Calculator is available at /calculator on this site. It generates personalized protocols, vial recommendations, and detailed dosing schedules based on individual parameters. Access is free for research purposes.
What is the reconstitution process?
Reconstitution typically involves mixing the lyophilized peptide with bacteriostatic water (BAC). Detailed reconstitution instructions, including exact volumes and unit calculations, are provided in our Reconstitution Guide available in the calculator and product pages.
Do you work with international institutions?
NEXGN LAB serves research institutions worldwide. However, orders must comply with local regulations and import laws of the destination country. Contact us for international ordering requirements.
