How can we help?

Yes, every single batch of our compounds undergoes rigorous third-party HPLC and Mass Spectrometry testing to guarantee purity levels of 99% or higher. We publish the Certificates of Analysis (COAs) for all active batches directly on our Lab Results page.

Lyophilized (freeze-dried) peptide powders should be stored in a cool, dry place away from direct sunlight. For long-term storage (over 30 days), storing them in a freezer (-20°C) is recommended. Once reconstituted with bacteriostatic water, the vial must be kept refrigerated (2°C to 8°C) and should ideally be utilized within 30 days to prevent degradation.

Orders placed before 2:00 PM EST (Monday - Friday) are dispatched the same day. Standard secure shipping typically takes 3-5 business days. We also offer expedited 2-day and overnight shipping options at checkout for time-sensitive research requirements.

Due to the sensitive nature of research compounds and strict quality control standards, we cannot accept returns once an item has left our facility, as its storage environment can no longer be guaranteed. If your order arrives damaged or incorrect, please contact our support team within 48 hours with photographic evidence, and we will immediately issue a replacement.
