Testosterone cypionate is an injectable form of the hormone testosterone. It is often prescribed to treat low testosterone levels in men and rarely to treat certain cancers in both men and women.
Some key points about testosterone cypionate:
- It is a slow-releasing ester of testosterone that is injected intramuscularly and absorbs slowly into the bloodstream. This allows for fewer injections compared to faster-acting forms.
- It is used in hormone replacement therapy to treat symptoms of low testosterone (low-T) like low sex drive, erectile dysfunction, decreased energy, and loss of muscle mass.
- Dosing is typically 200-400 mg every 2-4 weeks. It requires fewer injections than faster-acting esters like testosterone propionate.
- Side effects may include acne, oily skin, hair loss, breast enlargement, ankle swelling, and increased risk of sleep apnea.
Why is testosterone cypionate prescribed?
Testosterone cypionate is typically prescribed for men with confirmed low testosterone levels through blood work. Symptoms and signs of low-T that it can help improve:
- Low libido and erectile dysfunction
- Fatigue, irritability, and mood changes
- Loss of facial, body, and pubic hair
- Decrease in muscle mass and strength
It can also be prescribed in gender-affirming hormone therapy for transgender men and very rarely to treat breast and bone cancers in both men and women.
How does testosterone cypionate work?
When injected into muscle, testosterone cypionate is absorbed slowly into the bloodstream. There, it helps restore testosterone levels to normal circulating ranges. This helps alleviate low-T symptoms and brings back masculine physical characteristics.
It works by binding to androgen receptors that trigger changes in gene expression and protein production in cells to induce masculinizing and anabolic effects in the body.
Is testosterone cypionate safe?
When prescribed and monitored appropriately under doctor supervision at Rejuvenate Clinic, testosterone cypionate is generally safe for men. Still, there are some risks to be aware of:
- Potential increased risk of heart disease and strokes
- Liver damage if taken in high doses
- Blood cell changes like an increase in red blood cells
- Sleep apnea risk due to potential fluid retention
- Stimulation of prostate cancer growth
So regular blood work and screening are important for early detection of complications.
