All peptides are shipped lyophilized (freeze-dried) in sealed vials with ice packs and insulated packaging to maintain cold-chain integrity. External packaging is discreet and unmarked — no product names or company branding visible.
Most lyophilized peptides are reconstituted using Bacteriostatic Water (0.9% benzyl alcohol). We carry Bacteriostatic Water separately. Standard reconstitution protocols are available in research literature — we do not provide specific protocols.
