Description:

LifeTein offers the fastest turnaround times and the most reliable quality in the industry. Projects can move from conception to bench in as little as 3–5 days—helping you stay on track with demanding research deadlines.

Our Promise: LifeTein will ensure that eligible peptides (see Restrictions) ship within the stated turnaround times once the order is approved. Qualified orders that do not meet the posted turnaround time will receive a credit equal to 50% of the peptide cost toward a future LifeTein order. 

Accelerate Your Research: Move your peptides to the top of the queue at every step of the synthesis process. LifeTein peptides are synthesized and shipped up to 40% faster than the industry standard. Actual delivery times depend on the specific peptide and protein characteristics. 

Restrictions: LifeTein’s turnaround guarantee does not apply to orders requiring multiple modifications; peptides longer than 40 amino acids; multiple phosphorylation sites; or stapled peptides. Complex sequences may also affect turnaround times. Please indicate that your order is for RUSH synthesis at checkout. Standard synthesis (typical turnaround: 2–3 weeks) will be used unless otherwise specified. 

Orders placed before 5:00 PM EDT on U.S. business days will be considered placed the same day. 

Overnight Shipping: All orders ship via FedEx Overnight from New Jersey and typically arrive worldwide within 48 hours or less. U.S. and Canadian customers can expect delivery the day after the ship date. Customers in Europe, Australia, and Asia typically receive shipments in 2–3 days. 

Optional Local Pickup: Please contact us if you would like to pick up your peptides from our New Jersey lab. 

Invitation for Audit: Audits are an important part of service provider validation. Through a written or on-site audit, you can be confident that LifeTein follows the processes required to support successful peptide projects. 

Made in the U.S.: LifeTein never offshores or outsources rush peptide synthesis to third parties. Your rush peptide orders are produced in New Jersey and handled with accuracy and care, with respect for intellectual property requirements.
