its 100% fake version of sus, usually excipients like benzyl alcohol (BA) are typically added in amount of 9 mg/ml of formulation, this level is considered to be optimal for the local anesthesia. Fakers some times use BA as a solubility enhancer in order to have better solubility of low-quality API.
The concentration of BA could reach 5% in such formulations. In such dozes BA acts as a (*) cytotoxic agent which is induces local necrosis in the injection site. This is not very dangerous but extremely unpleasant. Being injected not deep (for example 10-15 mm in depth) such formulation causes necrosis between muscle and skin, this can cause serious discomfort and could be dangerous because injection site is continue bleeding thus could be infected. What else? I think that fake formulations do never content anti-oxidation agents. Factory made formulations could contain antioxidant or argon (noble gas) above the liquid. Usually, fakers unable to fill vials with argon during corking.
(*) cytotoxic agent
Light-headedness, dizziness, nausea, headache, skin and mucous membrane reactions. usually headache, and fever are the main presenting symptoms of high level of cytotoxic agent like a BA.
