injection technique thats what i mean mean, 1ml of oil takes me 4-5mins to inject useing a 2.5ml barrel and a 25g orange needle when i put the needle fully in me then it takes 15secs to inject the same oil useing the same stuff ... when the needle is like 85% in me I'd use 5/8 inch for delts anyway so you'll be fine leaving the pin out a bit
injection technique Warm the oil, or press harder. I take 30 seconds to jab 4ml of oil using the same pins and barrels as you and I stick the needles all the way in. 4/5 minutes is ridiculous. Time under tension or what? You must get cramps in your fingers.
injection technique must be something wrong with the needles i have then if they take that long i used to do quads with blues and inject 2ml in no time at all cheers guys
