Is there a base gel with really good staying power?

Going to the shop every time is a hassle and a waste of money.

I do nail extensions at home myself not to decorate my nails nicely, but to break my habit of biting them.

Since I have a habit of constantly lifting my nails, I keep trying to peel off my gel nails tomorrow as well.

I heard that peeling off gel nails tomorrow will cause severe damage.

Are there any base gels that don't peel off easily and have good staying power?

I've bought a few things online that are said to be good, but

It still feels like something is missing for me.
