Every Vial Leaves Our Facility Verified.
Before any compound ships from PeptidesNow, it passes independent HPLC testing, mass spectrometry sequence confirmation, and batch-specific documentation. Your Certificate of Analysis is generated from your exact batch — not an average, not a lot number estimate. We supply what the data confirms.

Research & Ordering FAQs
How do I reconstitute this peptide for research use?
How do I reconstitute this peptide for research use?
Add bacteriostatic water (BW) or sterile water to the lyophilized vial slowly along the inside wall — do not inject directly onto the powder. Swirl gently until fully dissolved; do not shake. The volume of solvent depends on your target concentration for the specific protocol. Reconstituted peptides should be stored at 4°C and used within 28–30 days. Refer to your lab’s standard operating procedure for compound-specific reconstitution ratios.
What is the shelf life of this peptide before reconstitution?
What is the shelf life of this peptide before reconstitution?
Lyophilized peptides stored at -20°C in a sealed, dry environment maintain integrity for 24–36 months from synthesis date. Room temperature storage is acceptable for short durations (under 3 months) if kept away from moisture and light. The synthesis and expiry date are noted on your COA. Once reconstituted, use within 28–30 days and store at 4°C.
Can I request the COA before placing my order?
Can I request the COA before placing my order?
Yes. If you need to review purity documentation prior to ordering — for institutional purchasing approval or protocol planning — contact our research support team with the compound name and quantity. We’ll provide the most recent batch COA on file. Note that your actual order will ship with its own batch-specific COA, which may differ slightly from the pre-order sample.
Do you ship internationally to research institutions?
Do you ship internationally to research institutions?
Yes — PeptidesNow ships to most countries worldwide with full tracking provided from dispatch. International orders are shipped in compliance with applicable customs regulations. Buyers are responsible for ensuring that importation of research compounds is permitted under the laws of their destination country. If you have questions about a specific destination, reach out before ordering and we’ll advise based on our current shipping experience to that region.
What bacteriostatic water should I use for reconstitution?
What bacteriostatic water should I use for reconstitution?
We recommend using 0.9% benzyl alcohol bacteriostatic water (BAW) for most peptide compounds, as it inhibits microbial growth and extends the usable life of the reconstituted solution. Sterile water for injection (WFI) is an alternative if BAW is unavailable, but the reconstituted solution should be used more promptly. The choice of solvent can affect peptide solubility — consult your protocol and compound data sheet for compound-specific guidance.
Are these peptides intended for human or animal use?
Are these peptides intended for human or animal use?
No. All peptides supplied by PeptidesNow are sold strictly for in vitro laboratory research purposes only. They are not approved for, nor intended for, human or veterinary administration, therapeutic use, or diagnostic application. Purchasing from PeptidesNow constitutes an agreement that the compounds will be used exclusively in a properly licensed research environment in accordance with all applicable local regulations.
