Proper Injection Techniques – Part 1

Must Know Information

Steroids are typically injected intramuscularly (abbreviated as IM) into large muscle groups. The most common injection sites being the gluteus (butt), quadriceps (front legs/quads), and deltoids (shoulders). Meanwhile, peptides such as insulin and human growth hormone (HGH) are typically injected subcutaneously (abbreviated Sub-Q). A Sub-Q injection is done into the subcutaneous tissue, the area between the skin and muscle. Subcutaneous injections are usually done in the lower ab area.

The most important thing when it comes to injection safety is keeping everything sterile and clean. A dirty injection site can lead to a very serious infection, which could require surgery or even amputation of the limb. As grim as that sounds, if you follow the steps and procedures that I will outline in this article series, you will have nothing to worry about!

What You Need For An Intramuscular Injection

  • 70% Rubbing alcohol or 99% isopropyl alcohol to sanitize the injection site and the top of the steroid vial
  • Cotton balls
  • Syringes – 3 milliliter (ml) syringes are the most frequently used
  • A sharp hazards disposable container (or a small plastic container with a screw on lid, such as an old protein supplement container)
  • A small band aid to apply to the injection site after the injection
  • A needle tip for withdrawing the oil from the vial with a length between 1 and 2 inches with 18 or 21-gauge size. (needle tip = pin)
  • A needle tip for injecting – a 23, 25 or 27 gauge needle with a length of 1 or 1.5 inches.

Note: The gauge of the needle refers to the diameter of the needle tip. Interestingly, as the gauge size increases, the diameter of the needle tip decreases. A small gauge number (that is – a thick needle) will allow the oil to be withdrawn from the vial quickly. On the other hand, a large gauge number will inject much easier into a muscle and create less scar tissue. This is why a small gauge needle tip is recommended for withdrawing oil from the vial (18G), and a large gauge needle tip (23G) is recommended for the injection.

What You Need For A Subcutaneous Injection

  • 70% Rubbing alcohol or 99% isopropyl alcohol to sanitize the injection site and the top of the peptide vial
  • Cotton balls
  • An insulin needle or a 1mL syringe with a 30 or 31 gauge needle, with a maximum length of 1 inch.

Note: Withdrawing peptides from a peptide vial will barely dull the needle, so changing needle tips prior to a subcutaneous injection is not needed.

  • A sharp hazards disposable container (or a small plastic container with a screw on lid, such as an old protein supplement container)
  • A small band aid to apply to the injection site after the injection

Where to Obtain Everything You Need For The Injection

The 70% rubbing alcohol, 99% isopropyl alcohol, cotton balls and Band-Aids can be purchased from any local drug store without any sort of prescriptions. Regarding the syringes, you can purchase them and needle tips from a local home care store or order them off of amazon.com. Order at least 5 extra syringes and needle tips in case you drop a needle during an injection. Never, under any circumstance, reuse needles/syringes or use a needle/syringe that has been dropped on the floor. Do NOT share needles or syringes with anyone, they are 1 time use.

Injection Sites For Intramuscular Injections

When doing an intramuscular injection, always inject the needle into the muscle at a 90-degree angle.

Injection Sites For Intramuscular Injections

Gluteal injection

The gluteus (a fancy word for your butt) is the most common injection site because it is a large deep muscle with few nerves and blood vessels. Hence the reason I recommend beginners stick with the gluteus as an injection site for their first cycle, since it is very hard to do something wrong there or hurt yourself. When doing injections in this area, it is a good idea to alternate butt cheeks for each injection, which should be done into the upper and outer region of the gluteus.

Nevertheless, the gluteus injection can be somewhat tricky of an injection site if you are a larger guy, as it requires you to twist around in order to inject. This problem can be solved by getting up on the big toe of the side you are going to inject into, which will help pivot your hip forward and allow you to reach your gluteus easier. Setting up a big mirror behind you to watch yourself inject also helps.

Regarding the injection volume, 3mL (3cc) is the max amount of oil that can be injected into the gluteus at once.

Quadricep injection

The quadricep is another very popular injection site. In fact, it is a simple injection site to use because you are able to sit down while injecting, can use both hands and the injection site is right in front of you. You can inject into any of the 3 quadricep heads, but the middle portion of the outer quadricep head has the least nerve endings and blood vessels, and it is the spot I recommend.

3mL (3cc) is the max amount of oil that can be injected into the quadricep at once.

Deltoid injections (shoulder)

The deltoid (shoulder) is another very popular injection site. Similar to the quadricep, the injection site is right in front of you, and you are able to sit down while doing the injection. You can inject into any of the 3 shoulder heads, but the middle of the side deltoid is the most popular spot.

1.5mL (1.5cc) is the max amount of oil that can be put into the shoulder per injection.

Bicep

The bicep is an injection site that should only be used by experienced steroid users. After all, it is a small site, so it requires a lot of precision and can be somewhat painful. For best results, inject into the middle of either of the two biceps heads.

1mL (1cc) is the max amount of oil that can be introduced into the bicep with each injection.

Tricep

Similar to the bicep, the tricep injection site should only be used by experienced steroid users. You can inject into either of the two tricep heads, but the outer tricep head (the tricep head closer to your chest) has less nerve endings and blood vessels. Just like with the biceps, inject directly into the middle of either tricep head.

1mL (1cc) is the max amount of oil that can be injected into the tricep muscle.

Pectoral

The chest is a commonly overlooked, but yet a very easy injection site to use. Inject into the lower and inner region of the pectoral - roughly one quarter of the way up and three quarters of the way across your pectoral muscle (starting from the outside of your body). Bringing the arm of the side you are injecting into across your body will make the chest muscle puff out and easier to inject into.

1.5mL (1.5cc) is the max amount of oil that can be successfully injected into the chest with each go.

Latissimus Dorsi

The latissimus dorsi (often abbreviated as lat) muscle is a very thick muscle with few blood vessels or nerves. It is a great option for an injection site, but the injection is difficult to execute by yourself. However, if you have a friend or family member who is willing to do the injections for you, the latimus dorsi is a great site to rotate into your regular injection schedule. With your arms held overhead, inject into the dead center of the latissimus dorsi muscle.

2mL (2cc) is the max amount of oil that can be injected into the latissimus dorsi per injection.

Injection Sites For Subcutaneous Injections

As mentioned above, a Sub-Q injection is an injection into the subcutaneous tissue - the area between the skin and muscle.

You can perform a Sub-Q injection anywhere you can pinch an inch of skin with your index finger and thumb. However, the abdomen is the most common and easiest area to perform Sub-Q injections into.

Drugs administrated through Sub-Q injections are done using an insulin syringe or a 1mL syringe with a 31gauge needle tip. The insulin syringe holds a maximum of 1ml, and has small increments alongside of the needle going in sets of 10, all the way up to 100. A reading of ‘10’ on the barrel would correlate to 0.1mL and a reading of ‘50’ on the barrel would correlate to 0.5mL
