as people know i have no experience with GH, but people say you will notice HUGE differences from just 4iu if its pharm GH.
some cant even use more than 4-5iu because of CTS, numb hands, sleepiness etc.
not sure about turkey pharmacies, but if its the real deal then 4iu would definitely make a difference.
i would use t4 with it though, not t3. t3 abolishes the protein sparing effects of GH, if you google real quick you will find a study.
you should also find some threads on the t4 vs t3 while on GH topic here
