I had a pituitary tumor when I was 22 and I have needed Testosterone therapy ever since. About 10 years ago, I developed a side effect from the injectable testosterone therapy that was made by a pharmaceutical company. I broke out when I injected the product. My doctor recommended a compounding pharmacy and I have been using a topical Testosterone therapy that has kept my levels normal for 10 years. I no longer get peaks and valleys from my testosterone levels. I apply 1ml every day and it's much easier than injecting or using a commercial product that costs hundreds of dollars and contained alcohol with makes me itch. I don't know what I would do without my compounding pharmacy.
