Frequently Asked Questions

Research peptides are synthesized amino acid chains used for scientific and laboratory research purposes. They are not intended for human consumption and are sold exclusively for research applications such as in vitro studies, cell culture experiments, and other scientific investigations.

No. All Everest Peptides products are intended solely for in vitro and laboratory research by qualified professionals. They are not drugs, foods, dietary supplements, or cosmetics, and have not been evaluated or approved by the FDA for human or veterinary use. By purchasing, you confirm you are a qualified researcher and agree to our Research Use Only Policy.

A Certificate of Analysis is a document from an independent, third-party laboratory that verifies the identity, purity, and quality of each batch. Every Everest Peptides product has its COA linked on the product page and published in our public COA database — always the COA for the batch currently shipping.

Within the U.S. we offer USPS Ground Advantage and UPS 2-Day Air — free standard shipping on orders over $150, and free 2-Day Air on orders over $250. We also ship to Canada via UPS Standard International.

Every order ships at ambient temperature. No ice packs, no gel packs, and no cold chain. Lyophilized powder is stable at room temperature, so refrigerated shipping is not needed and we do not use it. Each vial is vacuum sealed and packed with heavy protection so it arrives intact. Tracking goes out once the order is packed.

Yes! We offer free standard shipping (USPS Ground Advantage) on all U.S. orders over $150, and free UPS 2-Day Air on U.S. orders over $250. U.S. orders under $150 have a flat rate shipping fee calculated at checkout. Free shipping does not apply to international orders — Canadian shipping rates are calculated at checkout.

Orders placed before 3 PM EST ship the same day.

Two business days — not two calendar days. Weekends and holidays don’t count. An order that ships Thursday arrives Monday; one that ships Friday arrives Tuesday. Monday–Wednesday ships land two business days later (Tuesday ship → Thursday, Wednesday ship → Friday).

Yes. Once your order is packed, you'll receive an email with tracking information.

We take care of it — completely free of charge. Unlike other companies, we don't charge you for shipping insurance or make you file claims and chase down UPS or USPS yourself. If your tracking has stalled and the package looks lost, just contact our support team with your order number and we'll reship your order at no cost to you. It's that simple.

Yes — in addition to the United States, we now ship to Canada via UPS Standard International. Please note that free shipping promotions apply to U.S. orders only; shipping rates for international orders are calculated at checkout.

Peptide products are specified at ≥99% purity (HPLC), verified by independent US laboratory testing. The exact purity for each batch is documented on that batch's Certificate of Analysis.

Lyophilized (freeze-dried) powder is built for room temperature. Freeze-drying removes water, which is what keeps sealed vials stable without a fridge or ice pack. Keep the cap on. Store them in a cool, dry place away from light and humidity. That is enough for transit, for time on the bench, and for ordinary lab use. A few weeks at normal indoor temperatures will not damage sealed powder.

If you want the longest shelf life, put the unopened powder in a freezer at -20°C. Freezing extends the shelf life of lyophilized peptides, often to several years. It is extra protection, not a requirement. If a vial has been frozen, let it warm to room temperature before you open it so moisture does not condense inside.

After you reconstitute, the solution is less stable than the powder. Store it at 2 to 8°C and avoid repeated freeze-thaw cycles.

Every batch is independently tested by Freedom Diagnostics, a US analytical laboratory, not in-house. Each lot is characterized by HPLC (high-performance liquid chromatography) and LC-MS (liquid chromatography-mass spectrometry) as part of a multi-point quality panel, and no batch is released until it passes. Results are documented in a Certificate of Analysis (COA) available for every product.

Card payments are temporarily down. They will be back up soon. Right now you can use Pay by Bank (7.5% off) or Zelle (10% off). Learn more about our payment options

Yes. Select Zelle at checkout and place your order. Then check your email for Zelle payment directions with your order number and the exact amount to send. Your 10% discount is already applied to that amount. Once payment is received, your order ships, same day if it is before 3 PM EST.

Our traditional card processor is temporarily down. It will be back up soon. Until then, Pay by Bank and Zelle are available at checkout.

Pay by Bank is charged when you approve the transfer at checkout. Zelle is paid after you place the order, using the amount in your email. Once payment clears, we package and ship, typically the same business day or the next morning.

Card declines are usually caused by your bank flagging the transaction as unusual, an incorrect billing address (AVS check), or insufficient funds. The fastest fix is to contact your bank to authorize the charge, then try again. If it still won't go through, choose Zelle at checkout instead and save 10% — you'll get an email with payment directions, your order number, and the exact discounted amount to send after you place the order.

Yes. We use industry-standard 256-bit SSL encryption. Pay by Bank stays on your bank login through Plaid. We never store card details on our servers.

We accept returns of unopened, undamaged products within 30 days of delivery. Due to the nature of our products, we cannot accept returns of opened items. Please contact our support team to initiate a return.

If your order arrives damaged, please contact us immediately with photos of the damage. We will ship a replacement at no additional cost or provide a full refund.
