1.Find injection sites that work for you (“sweet spots”) and rotate them.
The deltoid (arm), vastus lateralis (thigh), and ventrogluteal (hip/butt) muscles are acceptable sites for IM injections. The common dorsogluteal injection site is no longer recommended.
2.Heat the oil.
Choose to warm the oil once it's in the syringe barrel under hot waer for a few minutes, or in a heating pad or warm the whole vial,which is up to you. Increasing the temperature to around body temp really makes a huge difference. It allows the oil to slide in quicker, which reducing the time that you can wiggle the needle around, and also reduces the amount of pressure requires to push in the plunger (same deal, less wiggling). Lastly, having injected intentionally cooled oil, room temp and warm oil,the chilled is the most painful, followed by room temp.Heating it reduces PIP, no doubt.
3.Use the shortest needle possible.
Performing an intramuscular injection is better (avoid the subcutaneous layer, it will hurt). For example, if you are lean you can use a 5/8" needle in you delts, no need for a 1" or 1.5" .Longer the needle, the more pressure and time required to perform the injection... Which means again, more wiggling. Also,it causes less tissue damage by penetrating less of the muscle. By using various lengths in different areas, which it's helpful.
4.Choose your gear wisely.
Use a needle that is long enough to penetrate deep into the muscle. Use a larger gauge needle for drawing up, then switch to a smaller gauge needle to inject.
5.Use the longest ester that will work for you cycle/plans.
Test is test. If you are running a long cycle, run a longer ester. No need to pin propionate, for example, daily when enanthate would be a fine choice. Generally speaking longer esters are available in higher MG/ML, as well as less painful post injection. This is no longer the case with concentrations over 300MG's/ML, as that will be arguably more painful than the short esters. Stick to 300MG's/ML or less.
6.Shorten your cycle.
If you’re injecting every 14 days, you might try moving to a 7 day cycle to see if injecting the smaller volume helps minimize pain.
7.Avoid water based AAS, if possible.
If you wish to run injectable winstrol or testosterone suspension, for example, opt for the oil based versions. They hurt significantly less, and also don't clog up the needles like water based sometimes do (this become a real pain in the ass). Winstrol and testosterone no ester are now readily available in oil versions, opt for those.
8.Go slow with virgin muscles.
Don't slam 3CCs into a muscle that has never been injected, taper up. Start with 1CC and add .5CC to the site each injection. At some point, you will learn which sites can hold various levels of oil.
9.Roll out/massage the area post injection.
About 5 minutes after you inject, start giving it a good massage. Move the oil around as much as you can. Ideally, you can put a heating pad on the area 5 minutes before you start rolling/massaging, as that seemed to help soften it all up. The massaging/rolling might be a tad bit uncomfortable, but it’s helpful.A hot bath works well here too.
10.Work the area out after pinning.
Try to time your workouts with your injections. When you know it's shoulder day, you inject shoulders about an hour pre workout. The area will feel a bit tight for the first 5 or so minutes during your lifts, just do a few good warm up sets, you will be good to go after that. Also, do not do the opposite and inject after you have trained an area, it sucks. Try and plan, it makes a big difference.
11.Cut the oil if you need to.
Some AAS are just more painful than others, it's a fact When I find a compound, injectable anadrol for me, that hurts a fair bit, I cut it with sterile grape seed oil (GSO). You can use whichever oil you prefer, GSO is easy to find for me and relatively cheap. Let's say I was going to inject 1CC of anadrol, I will add 1CC of sterile GSO to the barrel as well. It's not as much the volume of oil that hurts (until you get to large amounts), as it's the drug itself. Diluting it helps, a lot.
12.After sterilizing the injection site with alcohol, let the skin dry.
Penetrating the skin with the needle before the alcohol has evaporated can cause a stinging pain sensation.
13.Rotate the injection sites as much as you can.
If you are comfortable with trying new areas, it really helps give the older ones some time off to heal and rest.
Pain after an IM Testosterone injection is very common but there are numerous things you can do to minimize and even eliminate post-injection pain. In the end, every body is different and what works for one guy may not work so well for another. So, knowing that science doesn’t have all the answers yet, just do what works for YOU to maintain pain-free injections!
