Procedure

Applicants have cost-effectively synthesized Citrulline Nitrate by combining nitric acid and Citrulline, mixing with water, and leaving to crystallize. Further nitratization can take place, yielding Citrulline Dinitrate or Citrulline Trinitrate. An alternative implementation may comprise using Nitrous Acid (HNO2) instead of Nitric Acid (HNO3), thus yielding Citrulline Nitrite. Citrulline Nitrite has the same effects as Citrulline Nitrate, the only difference being that it requires one less step to yield Nitric Oxide (NO—). Mixed salts may also be used, such as in the non-limiting example of Citrulline Nitrate-Orotate.
