The present invention provides a muscular amino acids and peptides and nucleosides injection, which is extracted from the 
muscle and the 
cardiac muscle of healthy rabbit and is a freeze-
drying agent which is prepared by the sterilized water solution containing the compositions of polypeptide, amino acids, nucleosides, nucleotides, etc. The muscular amino acids and peptides and nucleosides is used for the 
adjuvant therapy of brain hypofunction and 
peripheral nerve 
disease caused by cerebral apoplexy and cerehral circulation insufficiency. The present invention belongs to the technical field of 
medicine. The invention introduces a preparing method which comprises the steps of cleaning, 
cutting into blocks, homogenizing, 
deep freezing, heating to boiled, separating the supernatant, depositing with acid and the base, depositing with the base, 
hot pressing, 
deep freezing, ultra-filtering, detecting, adjusting the proportion between the polypeptide and the 
hypoxanthine, and ultra-filtering. The muscular amino acids and peptides and nucleosides injection is prepared through the steps of sterilizing filtering, filling into containers, and sterilizing. An appropriate amount of accessory is added and the steps of sterilizing filtering, filling into containers, and 
freeze drying are executed for preparing the muscular amino acids and peptides and nucleosides for injection. The muscular amino acids and peptides and nucleosides and the preparing method of the invention have the advantages of excellent convenience, excellent wholeness, ensured product which satisfies the 
national standard, guaranteed 
virus blanching, injection sterilization F0 larger than 8, and high level of sterilizing guaranteeing.
