You should seriously consider brewing your own gear.
Do a melt testing to see if the product is genuine.
Learn the proper process of filtering with a .22 micron filter to keep it sterile.
Test powder is cheap, not faked much because it is easily available compared with a more exotic compound.
You decide what oils/ solublizers go into the mix, so PIP is minimal to non existent. Problems with UGL causing PIP are high mg/ml solutions, certain solublizers and too much benzol alcohol.
High mg/ml solutions need more solublizers to keep the steroid from crystalizing. These solutions commonly have ethyl oleate. Some people are fine with it others react badly to it, pain and swelling, general ill at ease.
Also the more benzyl alcohol(used to give an already sterile solution a longer shelf life) in the solution the more likelihood of pain. 1% is generally considered enough. Bill Roberts says you don't even need any and I have followed his advice so far to no ill effects. No PIP since using home brew test blend 200mg/ml, very minor to none with primo 100mg/mg.
