I was wondering about cycling myself after having been on BCP-157 and then a month later a BPC-157/Thymosin Beta 4 combo for some now-chronic bilateral lateral epicondylalgia (tennis elbow, but the medial/golfer's flares up) and tricep tendonitis.
Since I had never ran "research" before, I did go to a local clinic for my first doses and overpaid, but what I did learn is that you want to make sure that you're properly fasted at least an hour before and after injection so that an insulin response doesn't disrupt the BPC-157 or TB-500. These days I just source 3rd party, though, and haven't looked back.
When I first started, I believe my dosing was 250mcg in each arm twice daily for 5 days on, 2 days off. I'm still running 5 on 2 off with no complete break just because I'm afraid that going off completely could lead to more setbacks with the injuries since they're not fully recovered. It's the sort of situation where these injuries have to be re-trained, so I'm still active, but very cautious and not trying to set PRs.
I've gone up to 500mcg BPC-157 per side split daily with no side effects other than occasionally some bruising at the injection site, but that is only because I don't have much skin to work with around the forearms. It's hard to say if there is any extra benefit going up that high, so I'd say it's probably not worth it and in hindsight it might be better to do smaller doses (the 250mg) three times a day instead due to the short half-life. I also tried GHK-Cu, but that stuff leaves such bad post injection pain that I'm not sure if it's worth it.
I'm thinking about stacking PEG-MGF for immediately after my workouts to replenish the satellite cells, maybe through in IGF-1LR3 to switch over to after 4 weeks.
I briefly ran Ipamorelin and MOD-GRF, but I think it was giving me some carpal tunnel symptoms while exacerbating the injuries due to the extra pressure within the joints. I'd consider HGH, but it's expensive at clinics and I'd probably be better off just finding an underground source (no clue there).
