Does creatine make a difference?

Yes.

The studies all show it does help

Yes. It also has brain benefits.

I take it everyday, unless I forget to do so.

Powder, from what I've read here try to get one that is labeled creapure.

I've never noticed anything but the studies all support it so I take it anyway

Creatine is the best supplement in my opinion. You feel a major difference when you start taking it. You feel a major difference when you get off it.

I’ll usually take it in the evenings. Generally after a workout.

Just to chime in with personal experience:

Was in a rut of no real gains and pure maintenance for the last 3 years or so (I'm turning 51 this year). After a few months on creatine, I noticed a greater capacity for work in my workouts and started increasing my loads on all my exercises.

Gains since creatine:

Went from pulling 315 for 5 reps to pulling 365 for 5 reps on my deadlift.
Went from pushing 70 lb. dumbbells to 80 lb. dumbbells for 5 reps on my incline bench.
Went from struggling with pullups (I had some nagging tendonitis issues) to 5x5 pullups. One day a week, I'm doing 5x3 weighted with 25 lbs.
Went from 3x5 single arm overhead press with 24kg kb to 3x5 with 28kg kb,

Also have added Turkish Get Ups and dips back into my workouts which I'd lost the appetite to do. And yes, I know everyone is asking "where are the squats." Unfortunately, I mainly only do racked kb front squats, BSS, and lunges without really trying for gains on those exercises. Squats bother my back, so I don't work toward real increases in loads there.

Basically, I'm back to working out with the capacity and weights that I did in my mid-30s and just feel like I'm getting stronger.

I've definitely gained some water weight (and actual weight) which I need to address, but the strength (and physique) gains are legit.

The tadalafil took care of that...
