Tesamorelin was generally well tolerated in clinical trials. The most common side effects were joint pain, injection-site redness or itching, pain in the arms or legs, swelling from fluid retention, and muscle aches. It can also raise blood sugar, so glucose should be checked before and during treatment.13
Tesamorelin must not be used in people with active cancer, and any past cancer should be inactive with treatment complete before starting. It is also not used in people with pituitary or hypothalamic disorders (for example after pituitary surgery or head irradiation), and it should not be used during pregnancy or breastfeeding.13 Always inform your provider about all current medications, supplements, and existing health conditions before starting any protocol.
Consistent sleep, regular physical activity, stress management, and balanced nutrition support your treatment – deep sleep and body fat in particular are strong influences on natural growth hormone secretion.14
