You can significantly boost your growth hormone level by using nicotinic acid (Niacin) and exercise, have a look at figure 3 in this paper https://journals.physiology.org/doi/full/10.1152/japplphysiol.00534.2007 https://journals.physiology.org/doi/full/10.1152/japplphysio... . According to that paper it doesn't have a significant effect on the performance during exercise but it has a large effect on the serum level of GH. However it should be noted that this experiment was conducted on young healthy men and I have no idea if Niacin have the same effect in women or older men.
