Advice needed: Adding GHK-Cu to my recovery stack

I’ve been using BPC-157 (250mcg SubQ 2x daily) for a nagging shoulder impingement for about three weeks now, and while the inflammation has definitely subsided, I’m looking to accelerate the actual tissue repair. My clinic mentioned adding GHK-Cu to the mix. Does anyone have experience stacking these two? I’m a bit cautious about injection site reactions since I’ve heard GHK-Cu can be a bit 'spicy' compared to BPC. Also, with the recent Category 1 reclassification news, I’m finally feeling more confident that my pharmacy-compounded supply is stable and consistent. Any tips on injection sites or timing for the GHK-Cu to maximize the synergy with BPC-157?

It is great to hear BPC-157 is helping with your inflammation; at that dosage, you are likely seeing solid systemic benefits. Regarding your question, stacking BPC-157 with GHK-Cu is a popular strategy for tissue repair. BPC-157 promotes angiogenesis and collagen expression via the FAK/paxillin pathway, while GHK-Cu acts as a copper peptide that significantly upregulates collagen production and modulates fibroblasts. Regarding the 'spicy' sensation, GHK-Cu is notorious for stinging due to its acidic nature. Many experienced users mitigate this by using a larger volume of bacteriostatic water for dilution or occasionally buffering it slightly, though always ensure your source purity is high. Since both affect collagen synthesis, consider keeping your injection sites distinct to avoid compounding irritation. Always prioritize sterile technique, as GHK-Cu is particularly prone to contamination. This is just my community experience, so keep monitoring your progress and consult your clinic if reactions become persistent. Best of luck with the shoulder recovery!
