Turbovital is a brand name of IGF-LR3. There are many generic IFG LR3's out there and they range in quality from fake to poor to good. Turbovital is the brand of IGF produced by Hygetropin. Hyge is known to be one of the most consistent and well dosed GH's on the market today. Going with their name ensures that you are getting the best quality IGF available. Cost is more, but if you want to experiment with the best peptides you can, Turbivital would be a good choice. If you have a good source for generic, it will still do what it is supposed to. I just wouldn't expect it to be quite as strong...or more importantly, consistently strong. I have used some IGF generics that I loved, while with others, I couldn't feel anything. 

Usually, I dose my IGF low, around 30mcg to start, but if I want to see how strong it is, I will take a dose of 100mcg for one day, right before training. If it's good, pumps should be out of this world. Remember, IGF is "insulin-like". Some guys can go a little hypo so be prepared with extra carbs on hand, just in case.
