I’ve been on Cyp injections for about four years, I take 50cc (50mg) of 200mg/ml strength Cyp (it comes in 2 different strengths, 100mg/ml and 200mg/ml), once a week (a standard dose for TRT). Mine was due to 15 years of pain management (oxy destroys your body’s ability to make its own T). Injecting is so easy you can do it in your sleep. It’s IM (intra-muscular), not IV or subcutaneous, so multiple muscle options exist. Many use their butt cheek but you need a mirror and it’s awkward. Your thigh muscles are preferred, and many/most MD’s will nowadays steer you towards using your thigh. I’m 56 and have a full head of hair and no shrinkage issues. Average T levels for my age are roughly 250-750, and when I first went to my urologist, my number was double-digits, 67 I think. After just one 13-week cycle, my number was back in the “normal” range. And has stayed there ever since. It’s now anywhere between 600 and 1,000 whenever I get tested. Happy to answer any questions, just reach out to me.
