Accepted Answer

Currently, we ship within the United States only. International shipping may be available in the future. Sign up for our newsletter to be notified when international shipping becomes available.

Question 11

How are peptides packaged for shipping?

Accepted Answer

All peptides are lyophilized (freeze-dried) and sealed in sterile vials. Vials are placed in protective packaging with temperature-stable insulation to maintain product integrity during transit. Orders ship in discreet, unmarked packaging.

Question 12

Is shipping free?

Accepted Answer

We offer free standard shipping on all orders over $150. Orders below this threshold are subject to a flat-rate shipping fee calculated at checkout based on your location and selected shipping speed.

Question 13

What is your return policy?

Accepted Answer

Due to the nature of research chemicals, all sales are final. We cannot accept returns on peptide products once they have been shipped. This policy exists to ensure the integrity and safety of our products for all customers. If you receive a damaged or incorrect order, please contact us within 48 hours of delivery.

Question 14

What if my order arrives damaged?

Accepted Answer

If your order arrives damaged or you received incorrect items, contact us within 48 hours of delivery at support@peptide.express with your order number and photos of the damage. We will investigate and provide a replacement or store credit at our discretion.

Question 15

Can I get a refund?

Accepted Answer

Refunds are only issued in cases of verified damaged or incorrect shipments. All other sales are final. Refunds, when approved, are processed to the original payment method within 5-10 business days.

Question 16

How should I store my peptides?

Accepted Answer

Lyophilized (powder form) peptides should be stored at -20°C or below for long-term storage. For short-term storage (under 30 days), refrigeration at 2-8°C is acceptable. Once reconstituted, peptides should be stored at 2-8°C and used within the timeframe specified on the product label.

Question 17

How long do peptides remain stable?

Accepted Answer

Lyophilized peptides stored properly at -20°C can remain stable for 12-24 months depending on the specific compound. Reconstituted peptides have a shorter shelf life, typically 14-30 days when refrigerated. Always refer to the product-specific documentation included with your order.

Question 18

What solvent should I use to reconstitute peptides?

Accepted Answer

Bacteriostatic water is the most common reconstitution solvent for research peptides. Some peptides may require specific solvents such as sterile water, DMSO, or acetic acid solutions. Refer to the product documentation or Certificate of Analysis for compound-specific reconstitution guidelines.

Question 19

Can I buy research peptides online?

Accepted Answer

Yes. Research peptides are legal to purchase online in the United States for legitimate research purposes. Peptide.Express ships to all 50 US states via USPS Priority Mail, with same-day dispatch on orders placed before 2PM EST. All purchases are subject to our research-use-only policy.

Question 20

What is BPC-157?

Accepted Answer

BPC-157 (Body Protection Compound 157) is a synthetic peptide consisting of 15 amino acids, derived from a protein found in human gastric juice.
