When you enlist in the military, regardless of your service branch, you will have to complete basic training, which includes immunizations in the first week. During this week, called processing week, you will have to get the dreaded Peanut Butter Shot.

The Peanut Butter Shot is a name the military gives for a Bicillin injection.

What Does the Peanut Butter Shot Do?

The Peanut Butter Shot contains a high dose of Bicillin, which is capable of killing various bacteria and safeguarding a person’s immune system. When injected, Bicillin has the ability to kill yaws, respiratory infections, strep throat infections, rheumatic fever, yaws, etc.

Hence, it can do both: preventing and treating bacterial infections.

Since Bicillin can combat many types of bacteria, it is mandatory for service members across all military branches. For those that travel often (domestically and internationally), it is particularly important.

When you get the Peanut Butter Shot, it will be at the buttocks. This is to make sure that there is deep intramuscular absorption and a low chance of medical interruption of nerves or arteries.

The recruits will be called into an examination room as a group (usually of 10 to 15) and be instructed to pull down their trousers, revealing one of their butt cheeks while bending over. The recruit will also have to transfer weight to one leg so the entire side of the revealed butt cheek is weightless and not tensed up.

The medical staff will then stick a thick, long needle to a vial of Bicillin and inject it into the recruits’ butt cheeks. Unlike other shots, which are done in just a blink of an eye, it will take a while for the injection to finish as the Bicillin itself is thick.

Why is it Called the Peanut Butter Shot?

The Bicillin of the shot has a brown tinge and is thick and creamy, resembling peanut butter. Aside from that, it feels like peanut butter is being injected into your buttocks.

How Painful is the Peanut Butter Shot?

When the needle meets the butt cheek, it will sting and feel hot. If you tense up in response, it will hurt more. So, you need to fight off the urge.

After you get the shot, the injection site forms a huge and sore lump. It is often so painful that recruits cannot sit down for several days.

A lot of recruits also say that they encounter intense leg pains in the following days. In some cases, leg movement is also restricted. Upon shifting and moving, the lump causes aches.

Sometimes, the Peanut Butter Shot can even cause recruits to pass out.

Despite this, recruits are not excused from basic training activities. They are expected to show up and do well as they normally would.

Is the Peanut Butter Shot Scary?

The shot can be scary if you are afraid or cannot stand needles. Its needle is thick, long, and big. So, it can look a bit intimidating. But since the injection site is at your butt cheek, you will not see the needle being stabbed into your skin and it is slightly less scary.
