Hello, the question clearly indicates you are not an experienced synthetical chemist. As such, do not attempt to do this. The risk is not much in the injection of your self (which if you care about your life you would not attempt) but rather on the synthetic procedure. As far as I understand what this NAAK is, it’s a double injection, as such the two compounds would be in two separate syringes.

Instructions on how to synthesize those two compounds is readily available and detailed in scientific publications you can find online.

Now, the fact that you do not know how to find instructions on how to replicate the synthesis indicates that you do not have the necessary knowledge to do it and that you do not have the necessary equipment to do it. To perform the synthesis you’ll have to manage flamable and toxic compounds at high temperature under accurate conditions. This can easily turn into an explosion and a fire. Even if you accomplish the synthesis without killing yourself, you definitely do not have the equipment required to purify the compounds to a safe level. Get this straight: in general a university laboratory does not have the equipment necessary to produce something pure enough to be administered to human beings.

Now you have the information. If you’re searching for information on how the synthesis works, take a look in Google scholar. But be careful, those are technical documents which are difficult to understand and easy to misinterpret without formal training in synthetical chemistry.
