Gaining

Hi,
I was wondering if anyone had any positive experiences using herbal appetite boosters, specifically astral nutrition's 'ovrdrive'?
It gets good reviews on the company website, but I doubt they'd post any bad ones so I wanted real world experiences if anyone has any.
That particular brand was my focus simply because it came up quick as a UK available product early in a google search. Is it any good or can anyone suggest better?
I get palette fatigue really quickly so I find gaining hard. I'm looking for something that will help me get used to eating a lot at a time, so any tips are welcome, but I'd be keen to hear from anyone who could recommend a genuinely effective appetite booster.
Thanks
Dave

I find smoking weed a massive appetite booster, as you get the munchies, its a great way to make you want to eat, weed makes you feel very hungry. I've eaten 15 double king burgers after smoking.

Oh I do smoke weed and do get the munchies, but I was thinking about the supplements as something I could use throughout the day whilst at work. I can't sit and get high all day.
