Frequently Asked Questions

Orders placed before 3:00 PM local time on business days are dispatched same-day. Orders placed after the cutoff or on weekends and holidays ship the next business day. You'll receive a tracking confirmation email as soon as your order leaves our facility.

We ship via USPS, UPS, and FedEx depending on destination and selected service. Available options at checkout typically include Standard (3–5 business days), Priority (2–3 business days), and Overnight. Expedited options are recommended for time-sensitive research timelines.

We currently ship within the United States only. International shipping is not available at this time due to regulatory complexity around peptide importation in different jurisdictions.

If you are an international research institution with specific needs, contact us to discuss options. We do not guarantee availability for international orders.

Vials are individually wrapped in protective cushioning and packed in crush-resistant outer packaging. Lyophilized peptides are stable at ambient temperature during typical domestic transit durations — refrigeration during shipping is not required for properly lyophilized compounds.

All packaging is discreet. Outer boxes display no product names or branding that would identify the contents. The only external marking is the shipping label and return address.

First, check with others at your address and nearby common areas — carriers sometimes leave packages in unexpected spots. Allow 24 hours from the "delivered" scan, as occasionally carriers mark packages delivered prematurely.

If your package is still missing after 24 hours, contact us with your order number. We'll file a carrier claim and work to resolve it as quickly as possible. We take package integrity seriously and will make it right.

Lyophilized peptides should be stored at -20°C (−4°F) in a dry, dark environment — a standard laboratory freezer is ideal. Protect from light and moisture. Under these conditions, most peptides are stable for 24–36 months from the manufacture date stamped on the vial.

Do not store peptides in a frost-free (auto-defrost) freezer, as repeated temperature cycling can degrade compound integrity over time.

Reconstitution should be performed under sterile conditions:

1. Allow the vial to come to room temperature before opening to prevent condensation.
2. Add Bac Water (BW) or sterile water slowly along the side of the vial — do not inject directly onto the lyophilized cake.
3. Gently swirl or roll the vial to dissolve — do not vortex or shake vigorously, as this can break peptide bonds.
4. Allow any foam to settle before drawing solution.

The volume of diluent added determines your working concentration. Plan your dilution based on your research protocol's required concentration.

Once reconstituted, peptides should be stored at 2–8°C (refrigerated) and used within 28–30 days when reconstituted with Bac Water. Solutions reconstituted with plain sterile water should be used within 3–5 days.

Stability varies by peptide structure. For specific compound stability data, refer to the COA for your batch, which includes stability information from our testing partners.

Repeated freeze-thaw cycles should be avoided. Each cycle can degrade compound integrity through ice crystal formation and thermal stress on peptide bonds. If long-term storage of a reconstituted solution is needed, aliquot into single-use volumes before freezing so each portion is only thawed once.

The lyophilized form is the most stable long-term storage format — reconstitute only the quantity needed for your immediate research use.

No. All compounds sold by Prime 9 Labs are intended strictly for laboratory research purposes only. They are not approved by the FDA for human or veterinary use, consumption, or self-administration of any kind.

By purchasing from Prime 9 Labs, you confirm that you are a qualified research professional and that the compounds will be used solely for legitimate scientific research conducted in a controlled laboratory environment.

Purchases are available to:

• Individuals aged 21 or older
• Qualified research professionals, scientists, or institutions conducting legitimate laboratory research
• Buyers who agree to our Terms & Conditions and Research Use Disclaimer

We reserve the right to cancel orders and issue refunds if we have reason to believe a purchase is not for legitimate research purposes.

No prescription is required. Research peptides are sold as research chemicals — not as pharmaceuticals — and are legal to purchase for laboratory research use in the United States. However, it is the buyer's responsibility to ensure that possession and use of the purchased compounds complies with all applicable federal, state, and local laws in their jurisdiction.

"Research Use Only" (RUO) means the product is manufactured and sold exclusively for use in scientific research, not for diagnostic, therapeutic, or consumer applications. RUO compounds have not gone through the FDA drug approval process, and therefore cannot be legally sold, marketed, or used as drugs or medications.

This designation is standard practice for research chemical suppliers and academic reagent companies. It legally and ethically restricts use to qualified laboratory settings.

All sales are final. Due to the nature of research-grade reagents — which require verified chain of custody and cannot be resold once they leave our facility — we do not accept returns.

If your order arrives damaged, incorrect, or compromised in any way, contact us within 48 hours of delivery with your order number and photographs of the issue. We will send a replacement at no cost. See our full Shipping & Returns Policy for details.

Fulfillment errors, while rare, do happen. If you received a compound or quantity different from what you ordered, contact us immediately with your order number and a photo of the vial(s) received. We will ship the correct product with expedited shipping at no additional cost and arrange return or disposal of the incorrect item.

The fastest way to reach us is through the contact form on our website. We typically respond within one business day, often sooner.

For urgent matters related to a delivery or product integrity issue, note "URGENT" in your message subject and include your order number — these are prioritized for same-day response.

Reach out directly via our contact page. Our team is knowledgeable about peptide chemistry, COA documentation, batch specifications, and order logistics. We're happy to help with any question not covered in this FAQ.

If you're asking about a specific compound's research applications, we recommend consulting published peer-reviewed literature — resources like PubMed are invaluable for compound-specific research context.
