Taking tesamorelin for a year makes the hormone IGF-I go up much more in obese people with low growth hormone compared to taking a sugar pill.

In obese people with low growth hormone taking tesamorelin, the link between higher IGF-I and better muscle energy recovery is even stronger than in the whole group of participants.

After a year of taking tesamorelin, obese people with low growth hormone had much higher levels of IGF-I than those who took a sugar pill — proving the drug works as intended.

In obese people with low growth hormone taking tesamorelin, the link between higher IGF-I and better muscle energy recovery is even stronger than in the whole study group.

In obese people with low growth hormone taking tesamorelin, higher IGF-I levels are linked to better mitochondrial energy efficiency, measured by τPCr.
