TB-4 Frag vs full TB-500 for tendon rehab, what are you actually running?

My knee OA is still a work in progress tbh, and my PT thinks my left patellar tendon is grumpy too from compensating. I keep going back and forth between TB-4 Frag and full TB-500 for the tendon side of things.

The frag appeals to me bc the smaller size might get into the tendon better, and daily dosing seems easier to plan around. But I see a lot more human talk about TB-500 at 2-5mg twice a week for loading. Has anyone here actually tried the frag for a grumpy tendon and noticed anything? How long did you run it before you could tell?

Also wondering if running both at once is overkill or if there's any logic to stacking them during a loading phase. I'd rather not throw money at a protocol I can't justify. 🦵

Citations welcome if anyone's got them, I'm trying to read more and post less.
