Hey,

Try American Nutrition Company on Lyndhurst Terrace in Central.
(G/fl 23H Lyndhurst Terrace)- under the escalator.
They have well trained staff who all speak english and you can ask for Johnny if you'd like a specialists opinion.
They have the highest quality stuff on the market and can recommend weight gain plans depending on your body and goals.
I think there's also a 15% discount if you join as a 'member' which just means you put money on account and then use it to buy future products.
Hope that helps- all the best!
