There is no universal sweet spot for anything. Bodybuilding is a journey yes listen and study what others have done . But heed only you can find your sweet spot . That is the key to success. You need to just do it . Find a nominal starting point if you are new to this keep journal and records of all you eat do and feel . I have been a trainer for decades I consider my best advice is helping one understand that they are teaching themselves that each of us are the best teachers for us . Genetic , lifestyles , motivational compulsions experience good or bad all are variables that lend to us all having different experiences on anything . Hell even yourself over time will find that your responses or requirements change . The only constant in life especially bodybuilding is change . Never keep things the same . Maybe change then go back for a periodic time doing something but the body abs mind always Adapts - process defined as homeostasis- as a bodybuilder can be your biggest foe or best buddy . To go by another’s so called sweet spot just sets you up too fail . Especially if like some have found they need huge dosage of a particular compound . You use the least amount needed to progress . Is the golden rule . If you begin with mega dose when you are newer to something you’ve just taken away much of the potential benefit over long haul because you’ve burnt out your receptivity to it. Some guys bloat some guys stay shredded even when they eat like crap . Everything works symbiotically dietary habits , training methods are the main variables . PEDs enhance optimally those who understand this . Self control , patience , motivation are all components of strong mind . Strong smart training builds strong body . PEDs enhance these variables . You want the most for your money and your blood and sweat. Do ask and pick brains of the veteran guys on forums but ultimately it is you . You are the magic secret formula . Seriously 15 years totally natty almost two decades using chemical assistance- I’m not one that considered it cheating . Unless of course I’ve cheated Mother Nature - I respect the power of chemicals but I’m able to build and burn off too . Just realize that we all can have completely opposite experience sometimes . So always begin new things on lower side. I’m not saying ridiculous low but always remember you are your greatest teacher. Experience is your guide . Forgive me I’m just compelled to perseveration on that wherever I roam. Do continue to access forum . Hey is old guys weren’t lucky enough to have these when I began .
