Been on many protocols, low and high dose, but noticed no perceivable changes mentally (i.e. libido, energy) - basically was just like injecting water.
I do have low Vit D (19 ng/ml, range is 25-100). Does anyone know if having abysmally low Vit D would reduce the effectiveness of TRT?
As a recovering supplement-holic and veteran of 20+ years of supplement hype cycles, I have a bias against useless and/or dangerous supplementation. Vitamin D belongs mostly in the former category, though you can push it into the latter with high doses. Like antioxidant vitamins and like fish...

For those on HCG monotherapy, I have heard Dr Crisler discuss how he adds DHEA to the protocol for those men. I have also read albeit more on the bro science side that Vit D is also needed for HCG to work. I dont doubt Dr Crislers advice so I will supplement DHEA, but what aspect of Vit D would...
So I was deficient in Vitamin D (25.8 in 30-100 and that in the summer). I told my doctor that taking high doses of D causes me fatigue (I'm not alone if you search the internet). So he suggested injectable vitamin D. I did my first injection on Tuesday with a dose of 12500 IU, IM and from...

Does anyone know if taking Vitamin K2 is contraindicated in men receiving TRT? I read that warning on a bottle of K2 once but have never seen it again (even on the same brand) and searching online has provided no answers. Since it seems K2 is important in conjunction with D3, especially for bone...
