GH is sexually dimorphic. It requires roughly 3x the serum GH levels in females to reach the same endocrine IGF levels of a male. Span JP, Pieters GF, Sweep CG, Hermus AR, Smals AG. Gender difference in insulin-like growth factor I response to growth hormone (GH) treatment in GH-deficient adults: role of sex hormone replacement. J Clin Endocrinol Metab. 2000 Mar;85(3):1121-5. doi: 10.1210/jcem.85.3.6463. PMID: 10720049. To be honest, I have absolutely no idea why this is! I suppose we could get into all kinds of evolutionary adaptive discussions, but I haven’t found anything worth noting as to why. HOWEVER, the free fatty acid mobilisation properties of GH are just as potent in women as in men. Around 0.015iu/kg appears to be the ceiling dose to achieve this, so 1iu will fit the majority of women perfectly. I recommend taking 0.015iu/kg of bodyweight fasted in the am, 1 hour prior to cardio.
