I just bought some 30 gauge needles and i love them, no pain when inserting the needle and no bleeding after, the only downside is the oil goes through veryyyy slow. Im injecting npp and i always heat up the vial in boiling hot water before injecting. Any tips for making the oil go through faster? I dont know how some people are able to do it so quicky, i have to push down really hard and even then it takes about a minute to get it all inside.
