The usual protocol is to inject 1500-3000 I.U. every 4th or 5th day, for a duration usually no longer than 2 or 3 weeks. If used for too long or at too high a dose, the drug may actually function to desensitize the Leydig's cells to luteinizing hormone, further hindering a return to homeostasis. Timing the initial dose is also very crucial. If your were coming off a cycle of Sustanon for example, testosterone levels in your blood will likely stay elevated for at least 3 to 4 weeks after your last injection. Taking Human Chorionic Gonadotropin (HCG) on the day of your last shot would therefore be useless. Instead one would want to calculate the last week in which androgen levels are likely to be above normal, and begin ancillary drug therapy at this point. In this case Human Chorionic Gonadotropin (HCG) would be started around the third or fourth week. Likewise, after ending a cycle of Dianabol (an oral) your blood levels will be sub normal after the third day. Here you may want to begin Human Chorionic Gonadotropin (HCG) therapy a few days before your last intake of tablets, giving it a few days to take effect. One would also want to give some thought to the level of suppression that the cycle might have brought about. After an 8 week cycle of Equipoise for example, 1500-2500 I.U. would likely be a sufficient initial dosage. The lower amount of hormonal suppression one associates with this drug would probably not require much more. On the other hand, 750-1000mg of Sustanon per week might incline the user to inject a much larger Human Chorionic Gonadotropin (HCG) dose, perhaps as much as 5000 I.U. for the opening application. It may thereafter also be a good idea to reduce the dosage on subsequent shots, so as to step down the intake of Human Chorionic Gonadotropin (HCG) during the two or three weeks of intake.
