Green tea provides a slight boost to growth hormone; for those training naturally, even minor gains matter. Of course, you have to consume it consistently over time—this isn't an instant fix.
Specifically, the active substance in green tea is a compound known as epigallocatechin gallate (EGCG). In a study conducted by scientists at the National Center for Complementary and Integrative Health, it was confirmed that EGCG has a direct impact on growth hormone levels. Researchers studied two groups: the first followed a calorie-restricted diet supplemented with green tea for 90 days, while the second received a placebo.
Additionally, regarding parsley—after I started incorporating more of it into my diet a few years back, I noticed my libido spiked significantly that week. I used to add plenty of it to chicken soups, using both the root and the green leaves. It's quite tasty as well, depending on your preference.
Parsley contains a compound called apigening.
Apigening increases The amount of star in your testes…
Star is the binding protein that delivers cholesterol into the mitochondria inside your family jewels, essentially converting it to free testosterone.
Onions and Garlic act as anti-estrogen "blockers." Studies have been conducted on humans and livestock with positive results (links provided via .gov sites). Again, these are marginal shifts, but when combined, they are excellent for anyone training naturally.
Quote : Onions and Garlic Thes 2
These 2 vegetables give your breath a smell that the ladies can’t resist. Forget the ladies though, onions and garlic are anti-estrogenic, have some antioxidant activity, and go with almost any food.
They’re anti-estrogenic because of a component in them called quercetin.
Quercetin inhibits aromatase activity (study).
“Quercetin was found to inhibit human aromatase activity in placental microsomes.”
“The sharp decline in quercetin-induced aromatase activity at 100 μM could be explained by cell toxicity, as indicated by the 40% decrease in cell viability based on MTT reduction activity.” – study.
In one experiment rats that drank onion juice for 3 weeks tripled their testosterone levels. A 314%increase.
Onions – Rich in vitamin C and a good amount of vitamin B6 and manganese.
Garlic – Rich in vitamin C, vitamin B6, calcium, phosphorus, selenium and manganese. Also have a good amount of choline, copper, zinc, potassium, magnesium, iron, and thiamin. Superfood status.
