Why do new starters assume to think they need to take some form of supplement to TONE UP and generally get back from not being fat / unhealthy ??? All these new members do not know better but to buy supplements which totally over dramatize their product ! BULK ... whatever this product is that you wont share with this forum isnt some form of legal pro hormone or similar ! Because at the stage your at you wouldnt be ready for such a product ! In your case the only thing I would advise would be to buy a NO product or even a little creatine ! Your updated picture looks ok but as you agree your a long way from bulding quality muscle mass. TONE up first ... you still have amples of weight to lose ! Your pictures before you stopped training are your goal so when you get to that stage maybe then try something in the line of supplements to help your bulking stage ! To me it kinda looks like your attempting to bulk before you have a good starting frame.

You are trying to walk before you can crawl ! ... Aim on losing the gut and tone the arms ! All can be done perfectly natural and quick. Good luck
