Injecting - How to get the most out of an IV shot

[BlondieUK]

Hello.

Swim and his girlfriend both have access to clean needles etc and good quality amphetamines.

A usual session would involve Swim shooting first, and then doing the same for his girlfriend (this is due to the fact that her hands are unsteady and her veins are alot deeper than Swims)

Now we both know that swimmers are often advised never to let anyone else shoot them up, however we are both present when doses are prepared, and Swim always stops his girlfriends shot halfway through, checks it is in the vein and then follows through, always making sure that she is comfortable and content.

Now, Swims girlfriend always seems to get a far more intense rush than Swim, despite always doing the same amount, with the same amount of water etc.

Swius have considered that it may be due to tolerance, but have ruled this out after careful consideration.

Now swim is wondering what he can do to maximise the rush he gets from his shot?

Would more or less water make a difference? The speed at which his shot is injected? (Swim thinks that his girlfriends shot may be faster, considering it is alot easier, you can use both hands etc)

Swim is using 27g needles in 2ml syringes (usually filled to around 1-1.2ml mark)

Our lifestyles are very similar regarding food, sleep etc, so it must be down to the way the shot is administered.

Is there any basic information available, since Swim does find it very hard to find information on this on the web.

Swim is not planning on using until thursday, so if any information can be gathered in the next 36-48 hours Swim would definately appreciate it, as this will be his last weekend doing this for quite a while, so he wants to make it as good as possible.

Thankyou!
