Caplan assured me up to 300 mg of progesterone was safe
Conversely, in a study of non-cancerous cells, GHK appeared to promote the growth of NIH-3T3 fibroblasts, which are healthy cells often used as a standard model to examine cell division and growth

For example, in a 2003 study in mice, treatment with epitalon decreased the frequency of chromosome aberrations in bone marrow cells associated with age-related diseases such as acute myeloid leukemia and myelodysplastic syndrome.14 (In humans, these diseases primarily affect people who are over the age of 45, and more commonly those who are 65 or older.)15 16 By the studys end, epitalon increased the lifespans of the last 10% of survivors by 13.3%.14 To top things off, epitalon happens to have antioxidant properties,17 which means it can help mitigate the oxidative stress induced by reactive oxygen species, one of the chief causative factors of cellular senescence.13 Improved sleep health In a 2021 human trial involving 75 women, 0.5mg of epitalon per day was found to increase melatonin synthesis by 160% compared to placebo.22 That has positive implications for sleep health because melatonin a hormone whose levels decrease with age helps control when and how well you sleep.23 In turn, improved sleep health itself has positive implications for epitalons other therapeutic uses, as longer and higher-quality slumber is linked to better immune function, lower rates of age-related diseases (including cancer), and longer lifespans.24 That isnt to say that an epitalon dose will knock you out, only that it can help optimize your circadian rhythm
