I notice your answer to almost everything is to consult your doctor or a specialist like a urologist or ED expert (and sue them if they're wrong). That's sage advice, but not many in this forum have that option, for one reason or another. That's why we ask questions and seek the opinions and experiences of others. We're not dummies.
Sage advise or not, without question, experience is the greatest teacher and often proffessionals can only provide 'book learning'. Still, without the support of qualified people, you are asking for trouble. A good urologist WILL expect you to research what others say they have found but, you only get one dick and that's that. I think your suggestion that "We are not dummies" suggests to me that you wouldn't consult a professional but listen to the thoughts of others that you don’t know and have no possibility of validating what they say or suggest you ‘could’ do, pity. Don't worry, when you bust your member, I am certain there will be someone in the wings ready to 'look after' your lady for you.
A cock is not the carby in your car, stuff it up and all you do is go get another from the speed shop. Presently, you can not pop down to your local cock replacement shop for a new one. The ONLY SAFE testerone boosters are those provided by a QUALIFIED doctor. How the hell can you know what is really in preperations offered over the counter or over the internet. These sellers don't give a fig what happens to you or your member, just so long as they get your money. "Your not dummies" ...... well "caviate emptor" to you buddy.
