I think the dosages are just wild guesses. I know some have tried even 5 or 10mg a day. One guru said take a whole bottle of either BPC or TB at once, next month take a bottle of the other. Said he saw same benefits taking it this way instead of spacing it out. The multi milligram daily schemes were for healing the heart or kidneys, the effectiveness of which is just hypothetical.
Theoretically IGF-1 might be beneficial too for injuries, the "DES" is supposed to help locally. The dosages of the LR3 are hypothetical as well, who's to say it shouldn't be taken at 10mg a day like Increlex? But that would be 100 vials a day if 100mcg or 10 vials of the 1mg 
been puking all day the past couple days. thought it was pt-141 at first, or I'd accidentally taken some Semaglutide/Ozempic like I'd done before (1.5mg on accident was hell for a week), but no chance.. so I dunno what happened & never got around... no wait!! just remembered I did take one inj the first day after I got back from Red Light Therapy for 15min, cold plunge/sauna alternating for 30min, and an hour in the float tank...
500mcg TB-500 & 500mcg BPC157 in 10iu...
5iu went into the upper tricep/delt attachment.. near the armpit where I felt the 'pop'
the last 5iu went into my leg where the surgery incision keeps reopening due to swelling in my legs due to 'veinous insufficiency' or 'leaky valves', I have surgery for that scheduled next week some time I think. that one they'll go in through a vein in my thigh/behind my knee with a camera and soldering iron and permanently close the bad veins. if that doesn't help the lower leg enough, then they'll go into the lower leg and do the same thing. unsure if they're doing both legs or just the right. guess I'll find out then. only takes an hour they said.
anyways... that's another topic.
so, I think I'm gonna have to cut the concentration in half before I inject again, because it's annoying to try to inject 1iu into an area and shoot 3iu by accident.. so that 500mcg of each is now gonna be spread over 20iu. much easier to spread the peptide around to more than 1 or 2 muscle groups/joint.
I may do a 2on 1 off or 5 on 2 off just to stretch it out a little.
I thought about the igf-1, I'll have to re-up on gh soon so I may get some, but after hearing from some of Kuwait and Iran guys, I'd kinda want to run 250-300mcg/day, which would get pricey and not sure if I could rationalize that at 42.
I did love DES when I was in the peptide business... can't say what it did for growth, but it gave great pumps. I'd put 10-20iu in each muscle group I trained that day. which if I was training chest/delts could mean 70-80iu's in one workout because each head of the muscle got 5-15iu each. was always more conservative with IGF-1Lr3
