I think the discussion that my previous IV thread started was very productive and I would like to continue that with this as well. Please post your thoughts and feel free to add anything I have left out. I will edit my original post as we go along to include new information:

Intramuscular Injection:

Some drugs, including injectable steroids and hormones, must be injected into a muscle instead of a vein. The physical and psychoactive effects that result from an intramuscular injection of a drug come on much more slowly than those of an intravenous injection (half an hour to forty-five minutes versus almost immediately), although the overall, cumulative intensity of the effects and the experience are virtually identical.

Most if not all of the infection control and other safety precautions intravenous drug injectors should follow also apply to individuals who inject drugs intramuscularly. IM produces much less bleeding than intravenous injection, if any at all, but the risk of transmitting viruses and other blood-borne bacteria as a result of needle-sharing is as serious as it is with intravenous injection. In addition, people who IM run a higher risk for abscess formation, especially if what they inject has any particles in it whatsoever. When IMing, it is extremely important to inject only a solution that is as particle-free as possible.

Many of the substances that require intramuscular injection come pre-prepared in liquid form. To prevent contaminating your entire supply, be sure to use only a sterile needle and syringe when drawing the liquid up from the bottle in which it's stored.

Choosing an Injection Site

The buttocks, thighs, and upper arms are the three best sites, respectively, for intramuscular injection. The best is in the deltoid, the muscle on your upper, outer arm where your shoulder and your arm meet. If injecting into the butt, mentally divide each "cheek" into four equal sections and inject into the top right or top left outer section of each "cheek". You can also use the front surface of your thighs about six inches above your knee to about six inches below your hip, or the outer surfaces of your upper arms between your shoulder and your elbow. Always be careful to avoid nerves, blood vessels, or bones, and rotate injection sites to avoid bruising, abscess formation, etc. It is not uncommon for your muscle to be sore for a few days after an injection.

Be sure to carefully clean the injection site prior to injecting. Wipe in only one direction and not in a circular motion which will cause the dirt and germs to stay on your skin. DO NOT touch the injection site with your fingers after you've cleaned it. Routinely cleaning the skin prior to injection is one of the most important things you can do to reduce your risk of endocarditis, blood poisoning, and similar infections.

Try to relax the muscle prior to injection. This will result in a less painful injection and may prevent the soreness you usually feel the following day or two. When injecting into a muscle, insert the needle in one quick stab straight into the injection site at a 90° angle to the body. Nearly the entire needle should enter the muscle. You want to draw your plunger back slightly to make sure no blood comes into the syringe. If blood does appear, you've hit a blood vessel and need to pull out and try again. Inject your substance slowly.

Pull your needle out in the same direction and angle at which you inserted it. Because you injected into a muscle, there should be little if any bleeding. You might want to apply a Band-Aid in any case to prevent infection. Massaging the area lightly for a few minutes will help the drug absorb and reduce the pain.
 
Good info there.

Just a word on selecting the right needle for an intramuscular shot. For the majority of people, the needle needs to go deep (around 1 inch) in order to hit the muscle. Short needles like the common 1ml insulin syringes aren't going to get in far enough, and will instead deliver the drug into fat, or subcutaneously.

The needle gauge should also be larger than that used for IV. 25g should be a minimum, but 23g is ideal. Finer gauge needles (like 27 - 30g) can potentially break off in the muscle, so they aren't considered appropriate.

Also, on the issue of abscesses. While it's true that particles in the shot can form abscesses, these are often sterile abscesses. These don't usually cause too many problems, although they can leave permanent bumps under the skin as scar tissue develops.

The more problematic type of abscess is the septic abscess. These are caused by bacteria, and will usually not go away without antibiotics. Injecting IM increases the chances of a septic abscess, because the body is less able to fight off a bacterial infection if it occurs in muscle tissue.

If you are going to IM something that you made up yourself (as opposed to sterile vials), make sure it has been boiled first (pref left to cool, then boiled again a couple of hours later) to ensure sterility.

The reason for heating it up twice is that some of the pathogenic bacteria that are really bad if IM'ed form spores that will survive a first heating. The sort of thing I'm talking about are things like Clostridium perfringens, that causes gas gangerene - an abscess from this bacterium can lose you a limb (or even your life), and is only a threat if introduced via the IM route (if IV'ed, the immune system deals with it very quickly)
 
i started doing alot of IM shots after my ketamine addiction. i did all my k IM, so i became educated about this type of injection. it's very easy and quick. one could easily do IM shots while walking done the street in public. i did.

after experimenting with different location (never in the calves...ouch), i mainly stuck to the side of my thighs and the deltoids.

i did get an abscess once from IM heroin in my thigh. it hurt to walk for a couple days, and then the abcess went away, but i had temporary nerve damage (no feeling) for more than a couple months. it took a while for the nerves to grow back, but they did, and i have no permanent damage. just a heads up. after that, i stuck to the deltoids. i did all my heroun IM for years. i think it helped me, becuz i can definitely say IM heroin is less addictive than IV, even though you get the same high. you just have to have patience, sumthing most junkies don't have.

i am interested in what other kinds of drugs are good to IM...anyone? i always wanted to try IM dipropyltryptamine (DPT), but i haven't had the chance yet.
 
IM DPT is pretty spectacular, it comes on fairly hard and fast, and totally submerges you fairly quickly. I've read trip reports of people using 100mg of DPT by the IM route, and to be honest, that's more than I'd ever consider (40mg was pretty impressive, but I'm fairly sensitive to tryptamines). I would approach IM 5-methoxy DMT with caution - you don't get the sudden ego dissolution that you get with smoking - it's more that you can feel your ego dying in stages, and it ain't pleasant!
 
i use 1ml insulin syringes for IM... although i've never strayed from my deltoid.
