What are you doing with fentanyl if you have no tolerance? The tiniest amount could kill you, and fentanyl isn't even that great of high in my opinion. Its not all that euphoric and if you don't have a tolerance you can get much better, safer highs for cheap or just not do opioids to begin with. Also, What is the deal with the water? As far as I know Fentanyl HCl is barely soluble in water (only 200mg/L) or (200mcg/ml) I believe the citrate form is slightly more soluble. Interestingly, I just started a similar thread about pure Fent HCl powder and its solubility, and the only response I got was not to touch it at all, and I take roughly 800mg of oxycodone a day. Be Safe, Put away the fentanyl for a while!
