Is this a real GT frame?

Is it worth buying?

If you like it and will have fun building and riding it then, Yes.

If you are looking for good resale value or to make a profit on it, No.

Thanks, I'll get the serial no. soon

Yes, hopefully that will shed some light on it. Is it steel? If so, it's not an Avalanche.
