Is there anything better than fiasp? Fiasp makes me spike at around 4 hours after injecting insulin I wait 25 minutes before eating after injecting

The "best" insulin is the one that is best for you. And the gold star insulin is the one that we sed to produce before we got Type 1 diabetes,
We are all different and the only way of finding out what suits you best is trial and learning.

However, it is odd that a fast acting insulin which lasts 4 hours can make you spike when it runs out. Have you done a basal test recently to ensure that your basal dose is high enough? You may be covering it with the Fiasp for 4 hours. Bear in mind that your basal needs may differ during the day and night.

The other thing that surprises me as a long term Fiasp user, is that you need to take it 25 minutes before eating. I only need to prebolus that early if my BG is in double figures. If my BG is "in range" I can bolus when I start eating to avoid spikes and if my BG is in the 4s or 5s, I have to bolus after eating.
However, when my BG is in double figures, it can feel as if I am injecting water and then suddenly it starts working.

I really like Fiasp but when I switched from taking NovoRapid for more than a decade, Fiasp took some getting used to because if this variable activation speed.

Some people get on better with Lyumjev, similar profile to Fiasp. I've not had any personal experience of it.

If I was spiking after 4 hours I would be checking my basal insulin is covering that time period and consider increasing or splitting my meal time bolus. I use a pump so a square wave or dual bolus may work.

Bigotry, reliance on unsupported 'facts', unkindness, unfairness.
I find personally find that Fiasp works well though it’s slow to get a grip on high blood sugars and can dump me in the hypo arena if I wait too long before eating. If it were me, I’d suspect that I needed to adjust my basal dose. This can best be assessed by a basal check.

It’s probably best to do about four basal checks to cover the whole twenty-four hours.

If you’ve not done one before, there are helpful guides on the net. The one below might be useful for you.

I have tried that but had a allergic reaction to it

I have tried changing my basal to end up on the low end when I go to bed, we are all very different

People arguing over silly stuff
In theory you shouldn't spike 4 hours after injecting (but everything is possible as we're all different).

I found Fiasp became resistant (took ages to come down and was using tons of the stuff) and switched to Lyumjev - similar issues.

I worked out I needed really good site rotation for Lyumjev to work - imagine (but didn't try) the same would be true of Fiasp - try injecting to bits you don't normally inject and see if that helps - Fiasp is Novorapid with 'stuff in' to make it go-faster, it should be active for 4 hours in theory.

Hope you find a solution - if that doesn't work you could try Lyumjev

It also depends what you're eating. Does it spike after every meal, whatever you eat? I find pizza and chips (not together!) require a different strategy when compared with rice or boiled potatoes. Even if the overall carb load is similar.
