Duratestrin Chemical Information

estradiol cypionate - The cypionate salt form of estradiol, the most potent, naturally produced estrogen. Estradiol cypionate diffuses through the cell membrane and binds to and subsequently activates the nuclear estrogen receptor found in the reproductive tract, breast, pituitary, hypothalamus, liver, and bone. The activated complex binds to the estrogen response element on the DNA and activates the transcription of genes involved in the functioning of the female reproductive system and secondary sex characteristics.

testosterone cypionate - An eight-carbon ester form of Testosterone. The number of ester carbon atoms correlate with the half-life of the prodrug. Testosterone inhibits gonadotropin secretion from the pituitary gland and ablates estrogen production in the ovaries, thereby decreasing endogenous estrogen levels. In addition, this agent promotes the maintenance of male sex characteristics and is indicated for testosterone replacement in hypogonadal males. (NCI04)
