Question 1

What are peptides?

Accepted Answer

Peptides are short chains of amino acids that occur naturally in the body. They serve as signaling molecules for various biological processes and are used in research to study these mechanisms.

Question 2

What is bacteriostatic water?

Accepted Answer

Bacteriostatic water is sterile water containing 0.9% benzyl alcohol as a preservative. It is a standard laboratory reconstitution supply used to dissolve lyophilized research compounds in research settings. The bacteriostatic preservative enables multi-use draws from a single vial across extended research protocols. We offer it in 3mL and 10mL multi-use vials.

Question 3

Are your products for human use?

Accepted Answer

No. Our products are sold for research and laboratory use only. They are not intended for human consumption. All products are clearly labeled as such.

Question 4

Do you have Certificates of Analysis?

Accepted Answer

Yes, every batch is third-party tested. COAs are available upon request — contact nate@nexaralabsusa.com for documentation. Downloadable COAs will be added to each product page once we receive the PDFs from our testing lab.

Question 5

What testing do you perform?

Accepted Answer

We test for purity using HPLC (High-Performance Liquid Chromatography), identity verification through mass spectrometry, and endotoxin levels via LAL (Limulus Amebocyte Lysate) testing. All testing is performed by an independent ISO-certified laboratory.

Question 6

What is your purity guarantee?

Accepted Answer

We guarantee ≥99% purity on all our peptide products. Actual test results are shown on each Certificate of Analysis, and we often exceed this threshold. Our bacteriostatic water uses USP-grade sterility standards rather than a chemical purity claim.

Question 7

How long does shipping take?

Accepted Answer

Once your payment is confirmed, your order enters our fulfillment queue and is shipped via USPS from Texas. You'll receive an email with tracking information the moment your package leaves our facility — refer to the tracking link for accurate delivery dates. We currently ship within the United States only.

Question 8

How do I become an affiliate?

Accepted Answer

Accepted Answer

Create a Nexara Labs account and you're automatically enrolled. Earn 1 point for every $2 spent on confirmed research supply orders. Redeem points at checkout — 100 points = $5 off. Progress through three tiers (Researcher, Lab Partner, Principal Investigator) for higher earn rates and perks like free shipping.

Question 10

What payment methods do you accept?

Accepted Answer

We accept Cash App, Venmo, Zelle, and PayPal. After you place an order, you receive payment instructions by email with the exact handle and amount. Send the payment, confirm via the link in the email, and an admin manually verifies your transfer before the order is fulfilled. We do not accept credit cards directly because most card processors restrict research-peptide categories.

Question 11

How do I track my order?

Accepted Answer

Once your payment is confirmed, you'll receive an email with USPS tracking information the moment your package leaves our Texas facility. Use the tracking link in that email for the most accurate delivery estimate. You can also view order history and current status in your account dashboard.

Question 12

What is your refund and reship policy?

Accepted Answer

If a package is lost or damaged in transit, contact nate@nexaralabsusa.com within 7 days of the delivery date. Damaged-vial reports require photo documentation of the affected vial within 7 days of delivery. We will reship or refund at our discretion. Full policy details are on our Refund Policy page.

Question 13

Can I change my shipping address after placing an order?

Accepted Answer

Email nate@nexaralabsusa.com as soon as possible with your order number and the corrected address. We can update the address until the order has been picked, packed, and handed to USPS. Once a tracking number has been generated, USPS controls re-routing and we can no longer change the destination on our end.

Question 14

Do you ship internationally?

Accepted Answer

We currently ship within the United States only. We do not accept international orders, and we do not accept orders from U.S. jurisdictions where research-use-only peptide supply is restricted by local law.
