Agreed, 1000 mg of Maca is when I start to feel its effects. Though, for me it takes about a week before it becomes noticeable. You might also consider going for a gelatinized form, it's more potent and can help prevent digestive issues that some people experience with raw Maca.
As for Ashwagandha, Galaxyshock is right, an extract is the right way to go.
Yeah, 1:2 ratio of caffeine-theanine is what's typically used.
You might want to consider adding Magnesium and Boron to your stack. Look for Magnesium Glycinate or Lysinate. Avoid Magnesium Oxide and Citrate. The former is poorly absorbed in a lot of people and the latter can cause diarrhea.
Magnesium can help relax the body and mind and Boron can aid in its absorption, among many other benefits, including boosting levels of endogenous antioxidants.
(1) is essential for the growth and maintenance of bone
(2) greatly improves wound healing
(3) beneficially impacts the body’s use of estrogen, testosterone, and vitamin D
(4) boosts magnesium absorption
(5) reduces levels of inflammatory biomarkers, such as high-sensitivity C-reactive protein (hs-CRP) and tumor necrosis factor μ (TNF-μ)
(6) raises levels of antioxidant enzymes, such as superoxide dismutase (SOD), catalase, and glutathione peroxidase
(7) protects against pesticide-induced oxidative stress and heavy-metal toxicity
(8) improves the brains electrical activity, cognitive performance, and short-term memory for elders
(9) influences the formation and activity of key biomolecules, such as S-adenosyl methionine (SAM-e) and nicotinamide adenine dinucleotide (NAD+)
(10) has demonstrated preventive and therapeutic effects in a number of cancers, such as prostate, cervical, and lung cancers, and multiple and non-Hodgkin’s lymphoma
(11) may help ameliorate the adverse effects of traditional chemotherapeutic agents.
