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 — a Certificate of Analysis is available on request for any product. Email support@nexaralabsusa.com with your order reference and product, and we send the corresponding COA back. Our peptides are specified at ≥99% purity. See our Research Compliance page for our current posture on testing and documentation.

Question 5

What testing do you perform?

Accepted Answer

Independent third-party testing is currently paused pending a laboratory-partner transition. In the interim, our peptides are specified at ≥99% purity, and we will resume published third-party testing once the new partner is in place. See our Research Compliance page for details.

Question 6

What is your purity guarantee?

Accepted Answer

Our peptides are specified at ≥99% purity. A Certificate of Analysis is available on request, and our bacteriostatic water uses USP-grade sterility standards rather than a chemical purity claim. See our Research Compliance page for our current testing and documentation posture.

Question 7

How long does shipping take?

Accepted Answer

Once your payment is confirmed, your order enters our fulfillment queue and ships via USPS from Texas within 2–3 weeks. 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

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 our team verifies your transfer before the order is fulfilled. Card payments are being onboarded with a processor that supports research-compound merchants and are temporarily unavailable at checkout.

Question 11

Can I pay with a credit or debit card?

Accepted Answer

Not yet — card processing is temporarily unavailable while we complete onboarding with a payment processor that supports research-compound merchants (mainstream processors restrict this category). Until card checkout is live, we accept Cash App, Venmo, Zelle, and PayPal with manual verification. The card option will appear at checkout the moment it is available.

Question 12

Why is the payment amount a few cents less than my order total?

Accepted Answer

That's intentional. Each order is assigned a unique cents amount slightly below your total so our team can match your transfer to your order instantly and without error. Send exactly the amount shown in your payment email — don't round up or adjust it. The few cents' difference is yours to keep.

Question 13

I placed an order but never received the payment email. What do I do?

Accepted Answer

First check your spam or promotions folder — the email comes from nexaralabsusa.com and usually arrives within a couple of minutes. Still nothing after 15 minutes? Email support@nexaralabsusa.com with your order number and we'll resend your payment instructions. Don't send any payment until you have the email: it contains the exact handle and amount we use to match your transfer.

Question 14

Can I switch payment methods after placing an order?

Accepted Answer

Yes. Email support@nexaralabsusa.com with your order number and the method you'd prefer (Cash App, Venmo, Zelle, or PayPal) and we'll send updated payment instructions. Alternatively, unpaid orders expire on their own after 12 hours — you can simply let it lapse and place a fresh order with the method you want. Never send funds to any handle other than the one in your payment email for that specific order.

Question 15

How long do I have to send payment before my order expires?

Accepted Answer

Orders hold your items for 12 hours from checkout. If payment has not been received and confirmed by then, the order expires automatically and nothing is charged or owed. If your order expires but you still want the items, just place a new order — you will receive fresh payment instructions.

Question 16

I sent the wrong amount, or rounded the payment. Will it still go through?

Accepted Answer

Usually, yes — it just takes a little longer. Our team can still match your transfer using your sender name, payment method, and order reference, so use the "I sent payment" link in your email and we'll reconcile it manually. To avoid the delay next time, send exactly the amount shown in the email. If you accidentally overpaid, contact support@nexaralabsusa.com and we'll sort out the difference.

Question 17

I sent payment to the wrong account or username. What now?

Accepted Answer

Contact support@nexaralabsusa.com immediately with your order number and a screenshot of the transfer. Only the handle in your payment email is ours — if the funds went to that handle, we can locate and match them. If they went somewhere else entirely, open a dispute inside your payment app right away (Cash App, Venmo, Zelle, and PayPal all have a process for payments sent to the wrong person); we will assist with documentation where we can.

Question 18

My payment app is holding, flagging, or failing the transfer. What should I do?

Accepted Answer

Peer-to-peer apps sometimes hold first-time transfers to a new recipient or apply daily sending limits. If a transfer is pending on your side, wait for it to clear before confirming — we can only verify funds that have actually arrived. If it fails outright, switch to one of our other accepted methods (email us and we'll swap your order over) or retry after your app's limit resets. If anything is stuck, send a screenshot to support@nexaralabsusa.com and we'll work through it with you.

Question 19

How long does payment verification take after I confirm?

Accepted Answer

Verification is done by a human, which is why it isn't instant. Most payments are confirmed within a few hours during support hours (9 AM – 5 PM CST, Monday–Friday); transfers confirmed overnight are verified the next morning. You'll receive a confirmation email the moment your payment is verified and your order moves to fulfillment. If it's been more than one business day, email support@nexaralabsusa.com with your order number.

Question 20

What should I write in the payment note or memo?

Accepted Answer

Just your order reference (it looks like NX-XXXXXX and is shown in your payment email and on the order confirmation page). Nothing else is needed — the reference plus the exact amount is how we match your transfer. Please keep the memo to the order reference only.

Question 21

I paid but want to cancel my order. Can I get a refund?

Accepted Answer

If your order has not shipped yet, email support@nexaralabsusa.com with your order number and we will cancel and refund the transfer back through the method you paid with. Once an order has shipped, the standard Refund Policy applies — see the Refund Policy page for lost, damaged, and reship terms.

Question 22

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 23

What is your refund and reship policy?

Accepted Answer

If a package is lost or damaged in transit, contact support@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 24

Can I change my shipping address after placing an order?

Accepted Answer

Email support@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 25

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.

Question 26

How quickly do you respond to support emails?

Accepted Answer

Support hours are 9 AM – 5 PM CST, Monday through Friday. Most emails to support@nexaralabsusa.com receive a response within one business day. For order-specific questions, include your order number in the subject line to speed up the lookup.

Question 27

Do I need an account to place an order?

Yes. Nexara Labs is a verified-researcher platform, so ordering requires a free account. Creating one takes about a minute, satisfies the researcher-verification requirement, and automatically enrolls you in the rewards program.

Question 28

How do I place an order?

Accepted Answer

Browse the catalog, add the research compounds you need to your cart, and check out in three steps: shipping details, researcher verification, and payment method. You'll then receive payment instructions by email; once we confirm your transfer, your order enters the fulfillment queue.

Question 29

Is there a minimum order?

Accepted Answer

No minimum — order a single vial or a full research kit. Free shipping applies automatically to orders over $300 (and to the Principal Investigator rewards tier); otherwise a flat $16 USPS rate applies within the United States.

Question 30

Do you offer bulk or wholesale pricing?

Accepted Answer

Yes. For larger research-supply volumes and private-label programs we run a separate wholesale channel with confidential, approval-based pricing. Visit our Wholesale page to submit an inquiry and our team will follow up.

Question 31

Is my personal and payment information secure?

Accepted Answer

Yes. Payments are handled through the peer-to-peer apps you already use (Cash App, Venmo, Zelle, PayPal) — we never see or store your card or bank credentials. Account access supports two-factor authentication, and your order and profile data are protected behind authenticated, row-secured access. See our Privacy Policy for full detail.

Question 32

How should I store my research compounds?

Accepted Answer

Storage depends on the specific compound and whether it is lyophilized (freeze-dried) or reconstituted. In general, lyophilized peptides are kept cold and protected from light. Every product page lists that compound’s exact lyophilized and reconstituted storage temperatures under Storage Requirements — always follow the values shown for the product you ordered.

Question 33

How long do the compounds last?

Accepted Answer

Shelf life varies by compound and state. Each product page lists the specific lyophilized and reconstituted shelf life for that compound under Storage Requirements. Correctly stored lyophilized vials last considerably longer than reconstituted material.

Question 34

What is bacteriostatic water used for?

Accepted Answer

Bacteriostatic water is a standard laboratory reconstitution supply — sterile water with 0.9% benzyl alcohol as a preservative that enables multi-use draws from a single vial across an extended research protocol. We offer it in 3mL and 10mL multi-use vials as a research supply. For handling specifics, refer to the product page.

Question 35

Is your packaging discreet?

Accepted Answer

Yes. Orders ship in plain, unbranded packaging with no product or compound names printed on the outside. Any paperwork inside references your order number only.

Question 36

Where can I see my order history and status?

Accepted Answer

Sign in and open your account dashboard — the Orders tab shows every order, its current status (awaiting payment, verifying, in fulfillment, shipped), and USPS tracking once your package leaves our Texas facility.

Question 37

Why do I have to verify I am a researcher to enter the site?

Accepted Answer

Everything we sell is for laboratory and research use only. The verification step confirms you are 18 or older and a qualified researcher acquiring these compounds for research purposes — it is part of keeping the platform compliant and restricted to its intended audience. No products are intended for human consumption.
