For all of you guys who are taking hormones and peptides to increase your testosterone and IGF-I, keep in mind researchers have recently found that men with higher concentrations of these two hormones were more likely to be diagnosed with prostate cancer.
For every increase of five nanomoles in the concentration of IGF-I per litre of blood, meant a 9% increase in the likelihood of developing prostate cancer. For every increase of 50 picomoles of ‘free’ testosterone per litre of blood, the studies showed a 10% increase in prostate cancer risk.
The men were followed for an average of six to seven years to see if they went on to develop prostate cancer. Within the group, there were 5,412 cases and 296 deaths from the disease. A subset of 9,000 of men gave a second blood sample at a later date, to help the researchers account for natural fluctuations in hormone levels.
Looking at the population as a whole, the researchers say their findings correspond to a 25% greater risk in men who have the highest levels of IGF-I, compared to those with the lowest. Men with the highest ‘free’ testosterone levels face a 18% greater risk of prostate cancer, compared to those with the lowest levels.
Always check in with your doctor before beginning any hormone or peptide therapies. If you would like more articles on peptides and hormone therapies please comment and let me know.
