Bro relax, both have small half life so if you stop any symptom should go away fast.
You didnt say the dosage you are taking so i wouldnt know if you should lower the dosage, but no dosage of tren or test p should cause such symptoms, so i dont believe this is the right solution to this problem.
Heres what you do (in my opnion):
1- Pin again normally (check if it is really from steroids and not some other thing you might have ingested that caused an allergic reaction).
- If nothing happens in the next pin then you just go on with your cycle and it was probably something unrelated to steroids.
2- Considering the 2nd pin makes your symptoms worse, you will know that either one or both of them are causing it. So now you wait couple of days and pin test p alone. After that you wait couple of days and pin tren a alone. This way you will know which is causing the symptoms.
3- Contact your supplier and tell him what happend and which one (or both) is causing it and ask for a new vial and extra vial for making you go throught this.
Good luck bro.
