My focus is on power management techniques. I am not sure if you need these products to be effective. My advice is:
Read the label. You need to be aware of all the potential hazards associated with products with a high level of testosterone. I have written about this in this previous blog. You will need to do this before you buy. Make sure to look for and use products with an independent lab that will test for and grade any chemicals you may be exposed to. It may be worth a test to find out what level of exposure your body is actually at, and if any harmful effects are likely to develop. Read the label of every sex toy you own. Do they have a rating system? Does it include safety information? If so, read it and compare it with my blog. If there are chemical safety warnings, then be aware that the product may have been given a rating. Make sure to get information about what you are doing with your body before and after you use it. If you have ever used a sex toy, read the instruction manual for it, and if you're not sure, ask the manufacturer about it.
