Heroin Advice Needed

[EightySyxxEm]

So I'm quite new to H, or boy as it's called here. Ive been told the product is fairly decent. Greyish white powder. First time was darker grey almost purplish maybe. Always chunky. Powders up nicely. I started snorting just tiny lines because i wanted to be safe. Soon enough I felt the effects and really enjoyed it. Before long I wanted to try IV. However I couldn't hit the vein well. Clumsy at first. So my friend did it. I liked it well enough. Now i can do it myself. However the high isnt what I'd been expecting. There was no nodding off. No major rush. Yes there was a definite high. I believe my tolerence low. I get sick from too much dope. I have nothing to compare it too. Still a learning process.

So I am asking for any advice, tips and tricks for safety and correct methods of administration. I could divulge the process to make sure all steps are correct and precautions taken.
