Maybe don't do 10mg right away. If I did that I think I would've sent myself to emergency or something for heart issues. If you haven't tried this peptide before then increase dose slowly. I had less sides using nasal spray up to 1mg per day but even just at approx 750mcg subq I'd get heart palpitations
I do have unusual experiences like everyone loves mots-c but it makes me incredibly nauseated and weak so your mileage may vary but I'd rather be safe no matter what and go up slowly
