SubQ Injection Sites

Hi guys
I get lumps when injecting SubQ into the stomach fat. They’re annoying and impractical to deal with.

I wonder if it’s OK to inject with the Ksman recommended 29g insulin syringe to these areas:

Deltoid: How to Use HCG with Testosterone To Preserve Fertility, Libido and Testicle Size - YouTube

Quad?: Subcutaneous Injection - YouTube

In the quad video, wouldn’t that injection be very close to the actual muscle?

Is it needed to aspirate in either location?

Thank you.

Sub Q can be done anywhere where there is some fat.

Some get lumps in belly and not legs. Some vise versa.

The only thing that matters is how your body reacts and there is only one way to do that.

These lumps, how long does it take for then to dissapear? It has been 6 days since injection. It has reduced in size, no redness or puss. Hardly noticeable, only hurs slightly if I press on it
