hCG 18,000iu

Each vial contains 18,000iu of lyophilized human chorionic gonadotropin (hCG).

hCG (human chorionic gonadotropin) is a hormone that activates the same receptor as luteinizing hormone (LH), the signal that prompts the testes and ovaries to produce sex hormones. Researchers use it to study reproductive hormone signalling and hormone production in laboratory models.

This compound is supplied as a lyophilized powder and must be reconstituted with bacteriostatic water before use. Add the water slowly down the inside wall of the vial and swirl gently until dissolved — never shake. Use Pfizer bacteriostatic water only, never off-brand or "underground" diluent.

Before reconstitution, this product is stable at room temperature for short periods, such as during shipping, but refrigeration is recommended for longer-term storage. After reconstitution, it must be refrigerated. Keep away from direct light.
