I couldn't be arsed reading all 5 pages of the thread, so I'll just chip in here!
Creatine does work, but like anything when trying to get big, you can't just sit back and expect to grow!
1. Train
2. Eat
3. Rest
If you're after getting big, train 3 or 4 times at the most per week and keep the sessions to 45 minutes. After training, consume a good quality post workout drink (Like CNP's Pro Recover). Stick to basic excerises, if your not deadlifting and squating, then go join Fitness First.
You need to get in loads of quality protein and complex carbs, chicken, beef, eggs, fish (not tuna) or a shake. Every 2 - 3 hours. No excuses.
And rest. It's great going out on a Saturday with your tight top on showing off, but a load of booze / pills and lack of sleep do zero for gains.
Supplements. If you only have one supplement, make sure it's a quality post workout drink (simple sugars and protein), there's a "window of opportunity" after training, use it. Others such as creatine, try 6 weeks on / 4 off, in the 4 off, try something like Tribulus, a natural testosterone booster.
Find a quality supplement shop with staff who know what they're talking about (easier said then done!).
Train hard, eat well and you'll grow.
