Can I return a product?
Due to the nature of our research compounds, all sales are final. We will replace or refund products that arrive damaged during shipping on a per order basis. Contact us within 48 hours of delivery with photos of the damage. At our discretion we may provide your refund as a store credit.
Products & Compounds
What purity are your compounds?
All NetPeps compounds are ≥98% purity. Third-party certificates of analysis (CoA) from accredited laboratories are available for our products.
Are your products tested by a third party?
Yes. We provide certificates of analysis from independent analytical laboratories confirming compound identity, chromatographic purity, and concentration.
What is the difference between your GLP compounds (GLP1-T, GLP3-RETA, GLP4-CAG, GLP5-MAZ)?
These compounds differ in the number and type of receptors they are designed to engage. GLP1-T targets the GLP-1 receptor; GLP3-RETA engages GLP-1R, GCGR, and GIPR simultaneously; GLP4-CAG adds a fourth receptor target; and GLP5-MAZ engages five receptor targets. All are for laboratory research use only.
Do you provide dosing instructions?
No. Per our Research Use Only policy, NetPeps LLC does not provide dosing instructions, protocols, or guidance on human or animal use of any compounds. Researchers are responsible for designing their own research protocols.
Storage & Reconstitution
How should I store lyophilized peptides?
Lyophilized (freeze-dried) peptides should be stored at -20°C in a dry environment, away from light and moisture. Properly stored lyophilized peptides are stable for extended periods. Store reconstituted peptides in the main compartment of a refrigerator at 2°C to 8°C (36°F to 46°F), away from bright light, and use them within 28 days. Do not store mixed peptide solutions in the freezer, as freeze-thaw cycles break down the delicate amino acid chains.store in a cool dark space.
How do I reconstitute a lyophilized peptide?
Use research-grade bacteriostatic water (available in our Aminos & Solvent Research collection) for reconstitution. Add the solvent slowly to the vial, allowing it to dissolve without agitation. Reconstituted solutions should be stored at 2–8°C and used within the timeframe appropriate for the specific compound.
What is Recon Solution (bacteriostatic water) and why is it used?
Bacteriostatic water contains 0.9% benzyl alcohol, which inhibits microbial growth and extends the usability of reconstituted peptide solutions compared to standard sterile water. It is the standard solvent used in research peptide reconstitution protocols.
