General Information
Why Do I See Disclaimers Everywhere?
At Prime Lab Peptides, we operate strictly as a research supply company.
All products sold on our website are intended exclusively for laboratory and research use. They are not to be used as cosmetics, food additives, chemicals for human or animal consumption, drugs, medical devices, or any unapproved applications.
Listing a compound on our site does not grant any license for patent use, nor does it imply approval for any usage beyond laboratory research.
By placing an order, all customers confirm they are fully informed about applicable government regulations, understand potential health and safety hazards, and accept full responsibility for applying appropriate safety measures.
Important: Prime Lab Peptides reserves the right to cancel any order if there is evidence or suspicion that products may be used for purposes other than in-vitro research.
Where Is Prime Lab Peptides Located?
All orders are packed and shipped from within the United States.
We proudly operate and fulfill every order directly from our U.S.-based facilities in Miami, Florida.
What Is a Research Supply Company?
Prime Lab Peptides is a research supply company.
Our products are sold strictly for laboratory research purposes only and are not intended for human or animal use or testing.
Any implication or indication of such use may result in the immediate cancellation of your order.
Products & Storage
What Size Vials Do Your Peptides Come In?
All peptides are packaged in 3ml glass vials.
An exception applies to NAD+, which is supplied in a 10ml glass vial.
Our products are research reagents and have not been tested for safety or efficacy in any application other than in-vitro laboratory research.
How Do I Store Lyophilized Peptides?
For maximum shelf life, lyophilized peptides should be stored in the refrigerator or freezer prior to reconstitution.
When stored properly, they can remain stable for several years.
How Do I Store Reconstituted Peptides?
Once reconstituted, peptides should be kept in the refrigerator and used within a research-appropriate timeframe based on your laboratory protocols.
How Do I Store Bacteriostatic Water?
Store bacteriostatic water in a cool, dry place, away from direct sunlight.
It should never be refrigerated or frozen.
What Is the Best Temperature for My Products When Conducting Research?
Both peptides and bacteriostatic water should be brought to room temperature before use in any experimental setup.
What Are Research Peptides Used For?
Peptides are commonly used in biochemical and molecular biology research.
They play a vital role in applications such as protein purification, protein modification, and binding interaction studies.
Notice: Prime Lab Peptides is a research-only supplier. Our products are intended for trained professionals only. We do not provide usage instructions for any application.
Quality & Testing
Is There a Certificate of Analysis (COA) for My Peptide?
Yes. Each peptide includes a Certificate of Analysis (COA), accessible from the product page on our website.
You can match the batch number printed on your vial with the COA to view product-specific quality data.
Are Your Products Laboratory Tested?
Yes. Each batch is laboratory tested for purity, often by multiple independent labs.
Test results (COAs) are published directly on each product page.
If you wish to independently verify your product, you may do so through any licensed HPLC testing facility.
Purity Guarantee: If a product fails independent testing, we will refund your order in full, including shipping costs.
Do You Print Batch Numbers on Your Vials?
Yes. Each peptide vial includes a batch number printed on the label, which directly corresponds to the COA available on the product page.
This allows you to verify the specific analysis and purity data for your product.

We do not honor sale prices outside of the advertised sale period.
Sales occur monthly — be sure to subscribe to our email list and SMS updates to avoid missing the next one.
Is There Any Bulk Purchasing Offer?

Returns & Refunds
I Received the Wrong Item
Although rare, errors can happen.
If you receive the wrong item, please email us as soon as possible with your order number and a photo of the incorrect item(s).
We will ship the correct item(s) the same or next business day.
A photo is required to process a reshipment.
What Is Your Refund Policy?
Due to the sensitive nature of research materials:

- Orders already shipped or delivered: No refunds available
We offer free replacements for items that are damaged during shipping. If your item arrived damaged, please send us a photo so we can ship a replacement right away.
Important: Once an order has been shipped, we are unable to process refunds. This policy exists due to the nature of research materials, which cannot be restocked or resold once they leave our facility.
Do You Accept Returns or Exchanges?
Due to the sensitive nature of our research materials, all sales are final once shipped.
- Orders not yet shipped: Can be cancelled for a full refund
- Orders already shipped or delivered: No returns, exchanges, or refunds
This policy exists because research materials cannot be restocked or resold once they leave our facility.
