Melatonin lowers testosterone?

[Delita420]

NEL, Melatonin inhibits testosterone secretion

[rms80]

Interesting- I have taken it for years and I stay pretty jacked

[Delita420]

Ya, I thought the theory was that a deeper sleep allows your body to produce the testosterone it needs.

[rms80]

me too- guess we were wrong

It has been shown too increase prolactin in humans. I havent seen any studies regarding testosterone, and humans, for what its worth.

[Screwtape]

0.5mg/kg = 50mg for a 220lb person. Huge dosage, although I'm not sure how to translate the rat dosage into human terms.

50 mg would probably **** you up there is an equation to translate surface area and mg/kg from rats to humans- I will look around for it....

There also was a human study where melatonin taken orally pre-workout increased GH levels. If estrogen regulates GH, is there a link between the lower testosterone and high GH?

I cant really say for sure. Im not really positive on the relationship between GH and test. But as far as I know they're not mutual exclusive, meaning one doesnt have to be high, for the other too be low.

Fixed.

I've never heard about it inhibiting Testosterone, I've usied it in a blend (Scivation Knockout) and I haven't noticed any regression in the gym or in the bedroom.

I know it does promote REM Sleep and to release Growth Hormone.

I've heard about people using it for Pre Workout to spike GH, but I haven't tried it myself.

GH? Good deal!

[Kristofer68SS]

Isnt normal dosage 3 to 6 mg?

50mg...........jeezzz louise.

[Delita420]

Yes, normal dosing is 3 to 6 mg.

[planetfuzz]

I'd go into a coma if I took 50mg.

[Delita420]

Research shows that melatonin is effective at even less than 1 mg.

[thebigt]

so this study is based on doses given to rats that equal 50mg to people? that is 10x what a sane person would take, where is the relevance?

[Delita420]

Someone else is talking about rats. I'm not.

[luke1984]

I take 1mg before bed so I don't think I have to worry about this.

BTW, experiments on humans have been done with 6 GRAMS of melatonin with no signs of toxicity.

Muscletech is always talking about this study...adding Melatonin to everything they make..lol

You mean Yohimbine.....

I know they put Melatonin in their new testosterone booster, I saw it the other day and laughed at the ingredients.
