Simple answer is yes - However its far more complex and we all metabilize and react to drugs differently
I for example am extremely lucky with AAS i can run Tren 6-700mg with no sides gram plus of test dont even need anything. Never once had a need for adex, aromasin, caber, prami NADA just lucky
So long and short is its all about trial and error
Best advice i can give you is get regular bloods, as lucky as i may be i get bloods every 6 weeks when on cycle just to be on the safeside and always keep a regular eye on BP and HR
