First and foremost we do not advocate for anyone to try to lower their test levels... this is not meant to be taken in that manner... This is showing things that can and will possibly lower your test levels... to help you to know why your test levels may be down... NOT ways to make it stay down things change over time one being the fact that HRT/TRT is for life be careful what you wish for...
SECOND, I have not tried most of what has been listed here. I was guilty of asking the same questions but after doing some research of my own I found the answers.
HRT/TRT should only be used by those who need it and not solely as a body building supplement. Remember that HRT is for life and if you don't need it, don't get it.
Deca Durabolin (Nandrolone Decanoate):
A powerful 19 nor compound that will knock your natural test levels out completely, this compound causes 100% natural testosterone suppression with as little as a single 100mg dose.
The image below, taken from the steroid.com profiles shows how effective Deca is at testosterone suppression.
Note that at day 5 levels have hit rock bottom.
For those of you with already low testosterone, you may only need to take 100mg 24 hrs prior to show -200ng/dl.
Alternative to the Deca route:
Here I've taken a method tried by one of the members on this site and examining it further as to why it worked.
1) A week without hanky panky.
Researchers found that abstaining from ejaculation for six days had no impact on serum testosterone levels. On the seventh day, serum testosterone levels peaked to 145.7% of baseline, and then declined rapidly on the eighth day.(1,2)
2) Stay up playing XBox.
Testosterone production and release occurs during Sleep and Sleep deprivation may lead to lower serum levels of Testosterone.
4) Why go early? You got all day!
The time of day of blood sampling is an important consideration, however, and a blood sample drawn in the morning between 0800 and 1000h is generally recommended. There is a diurnal variation in testosterone in adult men, with highest levels in the early morning, followed by a progressive decline throughout the day, reaching the lowest levels in the evening and during the first few hours of sleep. Nadir values are approximately 15% lower than morning values, although the differences can be as much as 50% (3)
This I can attest for, I had blood work done twice in one day. My first test was done at 11am and my Total Testosterone came back at 423. Second test was done 5 hours later at 4pm and my levels came back as 269. This was on a 262-1531 scale. Free testosterone was unchecked.
5) A little alcohol never killed anyone, so make sure you drink allot!
Drinking no more than 3 drinks will keep you from having a testosterone dive.
So according to Tom Incledon and hundreds of other studies, binge drinking will destroy testosterone levels like no other. So loosen up and take a night out, just make sure it's a Testosterone only test and not a full chem lab so it doesn't throw up any red flags.
6) You are what you eat.
Cutting your calorie intake by more than 15 percent makes your brain think you're starving, so it shuts down testosterone production to wait out the famine. "There's no need to reproduce if you're starving," explains Thomas Incledon of Human Performance Specialists in Plantation, Fla.
Since you're trying to aggressively lower your testosterone you will want to stay away from high proteins and fatty foods. Consequently having too much protein in your diet could negatively effect your testosterone. We'll look at a few foods that encourage testosterone production in attempts to stay away from them for a few days.
1) OYSTERS
WHAT'S INSIDE: Protein, magnesium, lots of zinc
2) LEAN BEEF
WHAT'S INSIDE: Protein, iron, magnesium, zinc, saturated fat
3) BEANS
WHAT'S INSIDE: Protein, fiber, zinc
4) POULTRY
WHAT'S INSIDE: Protein and little fat
5) EGGS
WHAT'S INSIDE: Protein and cholesterol
6) COTTAGE CHEESE (1% MILK FAT)
WHAT'S INSIDE: Protein with very little fat
Now for Cigarettes.
Testosterone Levels after Cigarette Smoking.
Baseline Testosterone Levels in the Nicotine Groups. Baseline testosterone levels averaged 478.2 ± 38.45 ng/dl in the high nicotine cigarette group and 454.2 ± 37.3 in the low nicotine cigarette group, and these values were not significantly different. Baseline testosterone levels averaged 550.5 ± 30.1 ng/dl.
Also, there were no significant differences in baseline testosterone levels before high nicotine cigarette smoking.
Conclusion here is that cigarettes aren't the best way to lower your testosterone, in fact they might not even effect it all that much so unless you're into smoking a doobie every now and than, go ahead and bypass this.
