I was diagnosed with a pituitary tumor in Oct. 2013 and have since had it surgically removed and have gone through radiation treatments to prevent its reoccurrence. My endocrinologist has put me on testosterone supplements because my T level was low due to the tumor. My Dr. originally prescribed the use of a gel supplement but my insurance declined to cover any of them so I'm stuck (pun intended) with using an injected supplement. I must say that after my 1st injection I feel better than I have in months and I am finally feeling good enough to get back to bike riding. Since I was never on any of the gel supplements I cannot compare them to the injection in regards to how they make me feel but one thing I can say is that my wallet will be much happier. Gels are very expensive around $400 compared to $70 for the equivalent amount of serum (these are rough figures so don't beat me up if they are a bit off, the point being is that gels are way more expensive than serum). Since I have no idea how long my T level has been low I am very curious how my riding performance will compare. Oh yeah I am 55 years old.
