The length of the ester chain affects the half-life of the drug in the bloodstream. The longer the ester chain, the longer the half-life (in most cases). This can be extremely useful when trying to keep even blood levels of testosterone for optimal muscle growth and tissue recovery.
Testosterone Suspension- this drug is pure testosterone in sterilized water. There is no ester attached and the testosterone is biologically active at 100%, upon injection. The testosterone is suspended in tiny crystals within the aqueous solution which is why the "suspension sting" occurs upon injection. The crystals begin to dissolve very rapidly upon injection (there is no added partition coefficient because there is no ester attached slowing the absortption of the drug). One hundred milligrams (100mg) of testosterone suspension, is, literally 100mg of active drug. The half-life of the drug is from 12-36 hours depending on the state of your metabolism and the prescense of other drugs.
The cyp with the longer ester will take longer than this. So in the first 2 weeks the full amount of cyp is not present in the body.
