Frequently Asked Questions
Who is Better Peptide?
Better Peptide is a U.S.-based supplier of research-grade peptides, each tested by independent third-party labs to ensure 99%+ purity and verified quality. Every vial includes a corresponding Certificate of Analysis (COA) for full transparency and confidence in your results.At Better Peptide, our mission is simple - so you always know you’re getting Better.
Where are you located?
All of our products are shipped directly from our Virginia facility.
What quality control measures do you use?
Our peptides are kept in cold storage to preserve their potency and stability. All raw materials are tested to ensure both purity and potency before formulation.
We also partner with independent, third-party laboratories in the United States to perform additional testing. Verified lab results are posted as soon as they become available.
Can you instruct me on how to use your research products?
Our peptides are supplied in a lyophilized (freeze-dried) powder form. This means they are not provided in liquid form.
What form do your peptides come in?
Our peptides come in a lyophilized (freeze-dried) powder form - meaning they are not in liquid form when shipped.
Lyophilization helps preserve the peptide’s stability and integrity during storage and transit.
Since our peptides are supplied as a lyophilized powder, they are typically reconstituted in research settings using bacteriostatic water, bacteriostatic NaCl water, or sterile water.
What is a COA?
A COA (Certificate of Analysis) is a lab report verifying a product’s identity and purity. It confirms the results of third-party analytical testing.
When will my order ship?
Orders placed before 3 PM EST are processed and shipped the same day from our Virginia facility. Most orders leave our warehouse within one business day. Please note that delivery times may vary, as transit time depends on the postal carrier’s route from Virginia to your location.
How do I track my order?
Once your order ships, a tracking link will automatically be sent to the email used at checkout. You can use this link to monitor your shipment in real time.
Do you ship internationally?
We currently ship only within the United States.
How long does shipping take?
We recognize the importance of prompt delivery in research settings. Orders placed before 3:00 PM EST are typically processed and dispatched the same day. Orders placed after 3:00 PM EST are shipped the following business day, unless it’s a weekend or holiday.
Standard USPS shipping usually takes 3–5 business days.
Do you accept refunds?
All sales are final. Due to the nature of our products, Better Peptide does not accept returns, exchanges, or issue refunds once an order has been placed. This policy ensures the integrity, safety, and quality of our research materials remain uncompromised.
