I went from injections to gel then back to injections.

I wanted to try the gel to keep my levels more stable.

It seems to vary a lot, but for me, the gel was way more expensive on my insurance.  Gel was $50/month, injections work out to about $5/month for me.

If I already have facial hair before starting any T therapy, what would be most noticeable if I begin the gel? I only want a low dose, so I'm not expecting drastic changes, or fast changes, just something to look for.
