Every shipment to California includes cold-chain gel-pack packaging when the transit route or the specific peptide requires it. There is no additional charge for cold-chain — it is included in the flat shipping rate.
Shipments arrive in a discreet plain unbranded outer box. The shipping label carries only the address and standard postal markings; there is no mention of the contents on the outside of the package.
