Copy cells from range "C3" to "F3" with loop and blank field

Hi ,
I have recorded this macro ,but I do not know how many times I do have to repeat this I am quite new to VBA for excel
so I try to explain to you what I would like.
I have a xml file , which I inject into a excel 2010 file so far so good , but the lay-out is wrong I only need the "C" row because there are the info which I need , but in the wrong order , it always starts at "C3"
and I also need the next field "C4" .
but I need "C3" on "F3" and "C4" on "G3" next to each other and then there is a blank "C5" ( which I do not need)
but I need "C6" on "F6" and "C7" on "G6" and "C8" is a blank again and so on
and this until the end which could be anything , at one point the "C" row will be empty , so something like loop it until 3 blank fields on "C"
would do the trick.
I have recorded something like this
Range ("C3").Select
Selection.Copy
Range ("F3").Select
ActiveSheet.Paste
Range ("C4").Select
Application.CutCopyMode = False
Selection.Copy
Range ("G3").Select
ActiveSheet.Paste
Range ("C6").Select
Selection.Copy
Range ("F6").Select
ActiveSheet.Paste
Range ("C7").Select
Application.CutCopyMode = False
Selection.Copy
Range ("G6").Select
ActiveSheet.Paste

and so on
but looping it with always 1 blank in between is not so easy for me , and just keep recording the macro until 2000 or 3000 times
I think the must be an easier way, I have been try and looking it up via google , but couldn't find anything which fits my needs
so if someone has an idea this would be nice thanks

Attach a sample workbook. Make sure there is just enough data to demonstrate your need. Include a BEFORE sheet and an AFTER sheet in the workbook if needed to show the process you're trying to complete or automate. Make sure your desired results are shown, mock them up manually if necessary.

Remember to desensitize the data.
