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
So the shorter the Ester the more pip
That is kinda strange that ur long esters bite a bit
But what I posted above explains about the crystals that cause the muscle pain post injection
