Well, technically Helladrol is still AAS. It is on the mild side, but it is still an active steroid requiring supports and PCT and will shut you down.
It is a great choice for a first terms though. Run it for 6 weeks at 75/100/100/100/125/125
PCT should be
Clomid
Unleashed or test infusion
Formastanozol or post cycle
DAA
