That is one of the wisest responses I have seen as of yet. That will help you get the most out of your workout and in the event that you do decide to introduce steroids to the mix then you will b well educated on the path that is best for you and your goals. The best thing you can do is clean ur diet up first because that to me is the most important factor in growth then get you good solid beginners workout and begin acclimating your way in the gym letting your body grow to its full potential bc u have a history of lifting and so u have what they call muscle memory that will bring u back to where u were when u quit. Most ppl experience this between weeks 3-6 it really up to your body and genetics. Sounds like ur a hardgainer like myself so u will have push a little harder in the gym and make sure u have more than enough clean calories and quality protein. All of this will take u a good long minute and when u reach your personal plateau then It's time to introduce the enhancers. It takes patience and time but even steroids are not a wonder drug. If you do not implement diet, training and wisdom they won't make the difference u seek and can really do more harm then benefit. I hoped I helped u and go get it and make it happen
