What do you mean by testosterone? If you're chitchat steroids, yes they are reasonably undamaging, but can have some pretty fruitless side effects. If you're concerned that your test level are low, then turn see a doctor. Your doctor may put you on testosterone therapy.
IMO you're probably not ingestion enough, especially protein. Protein builds muscle and is used in copious metabolic processes. Protein provides amino acids which are the building blocks of life.
Your own = risk-free
Someone else's = not safe
check beside a doctor about this
dont do it
Check near your doctor! Can't stress that enough! Tests are
needed until that time any testosterone treatment!
My testosterone was so low that I be starting to develop
boobs, my strength was going, and I be gaining freight. I
told my doctor that I was going to buy some testosterone
supplements, and he become instantly concerned. He said
testosterone treatments CAN BE dangerous because they can bring to the fore blood pressure and cholesterol. So, check with the
doctor, first! I'm immediately using a gel called "Testim", and it's
going only just fine. I check in beside my doctor once every week to
see if my body is accepting the treatment.
CHECK WITH YOUR DOCTOR !!
IT IS VERY UNSAFE AND SHOULD BE USED UNDER MEDICAL SUPERVISION FOR MEDICINAL USE ONLY.
