Diet will dictate gains, even water weight can be curtailed through diet...

Now w/o any stats to go by - my "suggestion" would be to start off with a simple 10-12 week test (e)or(c) cycle (+PCT) to gage where ur at. your body isn't the same as it was 10 yrs ago. A good diet along with cardio and you'll be looking (and feeling) like a champ. if BF is/gets down around 10% u may want throw in some var (or winny) at wk 6 or so (test sides (if any) should be apparent by that point)

@Flip NOT a good idea to suggest/recommend tren to someone with limited experience in AAS

you could try some tren enanthate, prop and win. Tren and prop add good hard, dense muscle and the win will help to burn the fat. tren always made me feel very strong and the pumps I got with the tren and prop were incredible. remember to take an anti estrogen and clomid. bad thing about the tren in my experience is alot like deca dick. You cant shoot pool with a rope!! haha Good luck with it bro.

primo is the way to go if you don't want to put a lot of weight on. Forget pyramiding that's old school and doesn't give you optimum results. I would go with 200mg twice a week and you will get great results.

Your diet will determine how much weight you gain. Eat a lot gain a lot, eat like you usually do and maintain, eat like your 100lbs and you loose weight its simple.

Steroids do not provide weight gain, your diet does...
