Do not use it after cycle with other antiestrogens as things may worsen because of high amount testosterone-estrogen.
best way to use it is during cycle in small doses 250ius twise a week and stop using it 4 weeks before pct.
HCG aromatized in the body so its recommended to use an antiestrogen if high doses are administrated(more than 500ius week.)Inject 250ius twice a week on week 4 and week 8.
HCG is not needed if the cycle is no longer than 10weeks.
