Absolutely. You can review our latest lab results on our Lab Results page. Our analytical testing is conducted by Janoshik Analytical, an independent third-party laboratory to verify the identity, purity, and composition of our research products. Each CoA includes purity analysis, peptide sequence confirmation, and date of analysis.
Coming Soon: We’re actively expanding our lab testing. Currently, we have complete analysis reports for Semaglutide, Tirzepatide, BPC-157, CJC-1295 (without DAC). Stay tuned – we’re working with Janoshik Analytical to complete testing for our entire product line.
Delivery typically takes 2-5 business days. We ship from right here in the USA to all US addresses.
Every package comes with professional packaging, tracking updates via email, and does not require a signature upon delivery.
Our peptides are shipping in lyophilized form, which is stable at room temperature during transit. Once received, store unopened vials in a cool, dry place.
After reconstitution, store between 2-8°C (36-46°F), keep refrigerated, avoid repeated freeze-thaw cycles, and protect from direct light.
Our peptides are shipped in lyophilized (freeze-dried) form, which ensures stability during transit. This powder form is highly stable at room temperature and resistant to temperature fluctuations that occur during shipping.
Research has shown no significant degradation or loss of purity when lyophilized peptides are exposed to room temperature during typical shipping timeframes. Each batch is verified for purity upon production, and our stability testing confirms maintenance of product integrity during standard shipping conditions.
For optimal long-term storage after receiving your order, we recommend storing the lyophilized peptides in a cool, dry place until reconstitution is needed.
