Purity and batch documentation
Volta's release specification is >99% (HPLC). That is a threshold we set. >99% is the specification every batch is released to. The figure on a certificate is what a laboratory measured for one lot.
SideChain Analytics reported 99.8% by HPLC-MS/MS on September 27, 2026, lot VPGC100100.
