Hey everybody, so I had some issues with possible side effects but not sure...

So I recently started taking bpc157/tb500 mix to help heal torn rotator cuff and really bad tennis elbow. I started off very light at 100/100mcg to test out and had no bad sides. Day two I doubled the dose to 200/200mcg and still had no sides. I did notice a decent amount of pain relief and a bit more energy than usual. Day day I upped the dose again to 500/500mcg (dosing at night) and same energy boost and pain relief during the day. Still had no sides at this point. By day 5(last Friday) I did a small dose of 250/250 in the AM and went to work (did 500/500 the night before). Later that day, I felt tired and fatigue setting in around late afternoon. Later on that night I felt absolutely terrible with extreme body aches and pain all over, terrible headache, dizziness, fatigue, extreme chills like I was freezing! And insane night sweats. It felt like I had some kind of flu bug to be honest. I was laid up for 4 days fallowing that Friday night. Dizzy rds and headaches persisted for 5 days along with really bad night sweats.

So had anyone ever experienced anything like this with bpc157 and/or tb500? Do you think a viral bug sounds more likely? Also, has anyone had any experience with P Science usa?
