FAQs

Peptides are short sequences of amino acids found naturally in the body, where they contribute to a range of biological functions. All products we offer are intended exclusively for laboratory research use.

Your order status tell you the status of any order you’ve placed with us. Here’s a quick summary of what each status means:

• Needs Manual Review: Your order was flagged for security reasons and is being manually reviewed by one of our agents to make sure everything looks good. This process usually takes a few hours and rarely ever more than 1 business day. Hang tight! 
• Ready to Ship: Your order was processed and accepted, we’re working on preparing your products and sending them your way!
• Pending Shipment: Your order was processed, prepared, and is waiting to be picked up by our carrier.
• Partially Shipped: Part of your order has shipped and is on its way to you. Some items, however may arrive separately and at later dates.
• Completed: Your order was processed, shipped, and sent out to you. You'll receive a tracking number for your order and should expect it to show up soon! 
• Needs Payment: Your order was received, but we’re still awaiting payment to fulfill it. This status is usually related to a product subscription with a failed payment. You may need to update your credit card or other information.

No matter what sale we are running, we'll always ensure that you receive the highest discount possible here at Peptide Scientific Labs. We always honor the highest promotion to ensure you get the most savings. For example, if we're running a 45% OFF sale, and you have a coupon for 50% OFF, we will always honor your coupon.

However, we do not allow customers to stack coupons and promotions. So, in the example above, you cannot add your 50% OFF coupon to the 45% OFF sale for 95% OFF (though it would be nice!). In that situation, the highest of the two discounts will be applied to your final bill. 

If we run a Buy 1 Get 1 FREE (BOGO) sale, and you have a coupon for 55% OFF, we'll honor the 55% OFF instead of the BOGO sale. This is because a BOGO is, essentially, a promotion for 50% OFF two products, which is trumped by the 55% OFF coupon. As previously stated, the highest of the two discounts will be applied to your final bill. 

As a reminder, Gift Cards are exempt from all promotions and coupons. Happy shopping!

Here is the link to your account page where you can manage all of your subscriptions. Click on "Subscriptions" on the left-hand menu, about halfway down. You can cancel any subscription at any time, but you can also resubscribe, or subscribe to new products, at any time. Just find the subscription you wish to discontinue and click "cancel."

Your tracking number will be emailed to you once your order has been shipped. Once you log into your account here, you can also view the tracking number in your account. You can also track your package on our tracking page.

Once you receive your order confirmation email or have created an account during check out, you can find the tracking number in your order history or on the website of your shipping agent (UPS, USPS, FedEx).  

For further assistance, please contact the shipping agent or your local post office. This is because the tracking indicates that your package has been delivered but you have not yet received it. The shipping agent may be able to help you locate your package if you open a delivery claim with them. 

You should be aware that sometimes packages may not arrive on time, and tracking may also be delayed.

Peptides sit at a useful intersection between chemistry and biology. They are large enough to carry highly specific biological information, yet small enough to be synthesized precisely in a laboratory. That combination makes them powerful tools across a wide range of research areas — including receptor binding studies, mapping of signaling pathways, development of analytical reference standards, and investigation of cellular processes such as metabolism, immune regulation, tissue maintenance, and cell communication. Their specificity and structural tunability are exactly what make peptides a central subject of modern biochemistry, pharmacology, and molecular biology research.

No. Peptides and steroids are two entirely different classes of molecules with different chemistry, structure, and mechanism of action. Peptides are short chains of amino acids linked by peptide bonds — they are typically water-soluble and interact with receptors on the surface of the cell. Steroids, by contrast, are lipid-based compounds built around a four-ring carbon skeleton derived from cholesterol; they usually cross the cell membrane and bind to receptors inside the cell. Their regulatory classification also differs significantly. In short, a peptide is not a steroid, and calling one a version of the other is scientifically inaccurate.

Your order has been received, but we're waiting for payment to complete the fulfillment process. This often happens with product subscriptions due to a failed payment. You might need to update your credit or debit card before we can process and dispatch your order.

To update your subscription payment method:

1. Navigate to the Subscriptions tab in your Account.
2. Click "View" on the subscription item you'd like to modify.
3. Click the edit icon next to "Payment Details."
4. Choose an existing payment method or add a new card.
   • If selecting an existing method, click on it and save the changes.
   • If adding a new payment method, enter the required information and save your changes.

Your order was flagged for security reasons and is being manually reviewed by one of our agents. Once we confirm your order is not fraudulent and you are over the age of 21, your order will be approved and shipped.

If our agents require additional information to verify your account, you may receive a call from them. This usually only happens with first-time customers and once we verify your details, you're verified forever. This step is taken to prevent both, potential customers and existing customers from falling victim to fraud, scams, or theft. Age verification is required under federal laws and regulations. 

If our team determines that your order is not fraudulent and you are of legal age to consume our products, your order will be approved. If our team determines that your order is fraudulent or you are underage, or they can't get in contact with you after several attempts, your order will be canceled. 

This process usually takes a few hours and rarely ever more than 1 business day. No other action is needed from your side, just hang tight!

Safety is always context-dependent. Peptides themselves are a natural class of molecules — the human body produces thousands of them every second as part of normal cellular signaling. In a research setting, synthetic peptides are handled as experimental compounds whose safety and pharmacological profiles are still being characterized through controlled laboratory work. All products offered by Peptide Scientific Labs are lyophilized research materials intended exclusively for in vitro investigation and analytical use. They are not drugs, supplements, cosmetics, or food, and they are not intended for human or animal consumption. Any evaluation of safety in a clinical or at-home context falls outside the scope of what research-grade peptides are designed for.

Your order has been flagged for security reasons and is undergoing a manual review by one of our representatives. Once we confirm that your order is legitimate and you are over 21 years old, it will be approved and shipped.

If our team needs additional details to verify your account, they may contact you directly via phone call. This generally happens for first-time customers. Once your information is verified, you're set for future orders. This verification process helps safeguard both new and existing customers from fraud, scams, or theft. Age verification is mandated by federal regulations.

If we confirm that your order is legitimate and you're of legal age to purchase our products, your order will proceed. However, if it's determined to be fraudulent, you are underage, or we're unable to reach you after multiple attempts, the order will be canceled.

This review usually takes just a few hours, rarely exceeding 1 business day. No other action is required from you—just sit tight!
