Side effects to be aware of
Testosterone suppression

Recovery occurs after stopping but may take weeks to months. Post-cycle therapy (PCT) should be discussed with your physician.
HDL cholesterol reduction
CommonSignificant reduction in HDL ("good") cholesterol is consistently reported. Lipid panel monitoring is part of the protocol.
Fatigue or lethargy
CommonOften related to testosterone suppression. More pronounced mid-cycle or at the end of a cycle.
Headache
UncommonMild headaches are occasionally reported.
Water retention
UncommonMild fluid retention can occur.
Liver enzyme elevation
Requires monitoringDose-dependent liver enzyme elevation has been reported at higher doses. Liver function should be checked before and after the cycle.
Monitoring
Testosterone levels, LH, FSH, lipid panel, and liver function tests should be checked before starting, mid-cycle, and after completing the cycle.
