First week on Epithalon: Any tips for the injection site?

I finally started my Epithalon protocol this week after my doctor cleared me following the recent Category 1 reclassification news. I'm doing 10mg per day, split into two 5mg doses. I've noticed some slight redness and itching at the injection site, which I haven't experienced with my previous BPC-157 cycles. Is this common for Epithalon? I'm using a 30g insulin syringe and rotating sites between my abdomen and glutes. Also, for those who have run this for telomere support, how long did it take before you felt any subjective changes in sleep quality or energy? I'm really hoping this helps with my overall recovery and circadian rhythm, as my sleep tracking has been pretty erratic lately. Any advice on managing the site irritation would be appreciated!
