– http://www.prisysbiotech.com/ CRO preclinical research involves two main methods of animal testing. The first method involves injecting animals with small amounts of an active ingredient and monitoring their performance after the injection has been administered.
The second method of CRO preclinical research involves injecting active ingredients into the animal’s muscle. The injection of active ingredients into the muscle causes the muscle to contract, which then causes the drug molecules to travel to the nerve terminals in the muscle. As the drug molecules travel down the nerve fibers, the receptors in the receptor sites become activated.
