Pregnyl- HCG is used to stimulate natural testosterone production during or after a steroid cycle.

HCG is provided as a glycoprotein powder to be diluted with water, and acts in the body like luteinizing hormone (LH), stimulating the testes to produce testosterone even when natural LH is not present or is deficient. It therefore is useful for maintaining testosterone production and/or testicle size during a steroid cycle. Use of this drug in the taper is rather counterproductive, since the resulting increased testosterone production is itself inhibitory to the hypothalamus and pituitary, delaying recovery.
