Hi neilb and welcome
I'd also say don't get carried away with a lot of the stuff you see here and on other forums/magazines etc, like split routines/supersetting/pro hormones/shock routines etc. These are for people who have been training for a long time and have reached a plateau. Although its tempting it will be counter productive for you neilb.
Also, imho avoid all the supplements you see in health shops with the possible exception of a whey protein/creatine but see how you go first. In my view the other products are falsey marketed and always show some massive dude who certainly didn't get a physique by just taking the supplement they are advertising. 90% are a waste of money and tyou can get most for basic food sources.
For beginners it seems really confusing but its actually quite simple, a good training routine (no more than 3 times a week) + LOADS of basic foods + rest (don't under estimate the last 2)
Good luck neilb and any questions, no matter how dumb
just post.
Cheers
Mr S
PS I assuming you wanna put on overall bulk initially, ie beef yourself up rather than endurance/ pure strength etc
