What is NPR Research?
NPR Research was started to help people find answers to the most common asked questions about peptides and aminos
Where is NPR Research located?
NPR is located in Central Texas about 40 miles west of Austin Tx
Do you sale peptides?
No, we are research only and sale no products at this time, We do work closely with NetPeps LLC which is a research peptide supply company.
How accurate is this website?
As with any website we are subject to mistakes, we strive to be as accurate as humanly possible, but with any research or physician always seek out a second opinion, it's your health and you are worth it.
How do I store lyophilized peptides?
Most all peptides are sold in lyophilized form, meaning liquid is extracted to extend the shelf life of each product. Lyophilized peptides should be stored in the refrigerator or can be stored in the freezer for 1-2 years (give or take depending on the temperature they are being stored at). If your peptide is already reconstituted, keep it in the fridge, DO NOT store them in the freezer.
Best way to store bacteriostatic water
Bacteriostatic water should be stored in a cool dry place, out of direct sunlight. Never store bacteriostatic water in the fridge or freezer.
What are RUO peptides?
RUO stands for Research Use Only, NetPeps offers research peptides solely for research and development purposes, not for human consumption, medical, or therapeutic applications. Our research peptides should not be misconstrued or substituted as prescription drugs. We do not dispense any prescription medications and are not a pharmacy. The US Food and Drug Administration has not assessed the assertions made on our website. Products are not intended to diagnose, treat, cure, or prevent any medical conditions or diseases.
Common Dosage Mistakes to Avoid!
- Using sterile water without preservatives
- Not labeling your vial (forgetting how much water you used)
- Drawing air bubbles or inaccurate syringe mark
- Storing peptides at room temperature for too long
- Thinking “more = better” — especially with IGF-1 and GHRPs
Can I use sterile water instead of bacteriostatic water?
Technically yes, but BAC water contains benzyl alcohol which preserves peptides for up to 30 days. Sterile water must be used immediately.
How long does a peptide last after mixing?
If refrigerated and handled cleanly, most are stable for ~30 days.
Can I preload syringes?
Yes — preload 1–2 days at a time for convenience. Do not freeze.
Where do I inject peptides?
Most are subcutaneous (belly fat, love handle region). Some like IGF-1 are injected near the muscle (localized application).
