Is Cypon Advisable For Weight Gain?

I am 33 and I weigh around 57 kgs and height is around 176 cms, I would like gain at-least another 7-9 kgs. I play daily squash in the morning for an hour so have some physical activity. My appetite is on a lower side with high metabolism which causes difficulty in weight gain. Is it wise to have cypon ? if yes what should be the dose and any additional medicines.
