It is important to note that HCG should only be run while a user is still on cycle and not during PCT. This is due to human chorionic gonadotropin actually being suppressive to the hypothalamus pituitary testes axis. Obviously this is something to be avoided when attempting to "re-start" your natural testosterone production. Ensure that the last shot of HCG is taken within several days of the start time of post-cycle therapy so that it has cleared the system of the user and the compounds being taken for PCT can function as intended.
