Eurycoma longifolia Jack commonly known as Tongkat Ali in Malaysia, has been used in Malaysia to increase male virility and sexual prowess. The objective of this study is to evaluate sexual arousal in sexually sluggish old male rats, 24 months old and retired breeders, receiving 200, 400, or 800 mg/kg of various fractions of E. longifolia Jack, twice daily, for 10 days. Control rats received 3 ml/kg of normal s****e. The aphrodisiac effect was monitored by the act of yawning and stretching because yawning, either alone or associated with stretching, is considered an ancestral vestige surviving throughout evolution that promotes sexual arousal. The results showed that 800 mg/kg of E. longifolia Jack increased yawning by 50% and stretching by 16.7% in sexually sluggish old male rats, by 676-719% and 31-336%, respectively, in sexually active male rats, and by 22-44% and 75-100%, respectively, in middle aged, 9 months old and retired breeders. We conclude that the results of this study support the folk use of this plant as an aphrodisiac.

It has been reported that Eurycoma longifolia Jack commonly known as Tongkat Ali has gained notoreity as a symbol of man's ego and strength by the Malaysian men because it increases male virility and sexual prowess during sexual activities. As such, the effects of 200, 400 and 800 mg/kg of butanol, methanol, water and chloroform fractions of E. longifolia Jack were studied on the laevator ani muscle in both uncastrated and testosterone -stimulated castrated intact male rats after dosing them for 12 consecutive weeks. Results showed that 800 mg/kg of butanol, methanol, water and chloroform fractions of E. longifolia Jack significantly increased (p<0.05) the leavator ani muscle to 58.56+/-1.22, 58.23+/-0.31, 60.21 +/-0.86 and 62.35 +/-0.98 mg/100 g body weight, respectively, when compared with the control (untreated) in the uncastrated intact male rats and 49.23+/-0.82, 52.23+/-0.36, 50.21+/-0.66 and 52.35+/-0.58 mg/100 g body weight, respectively, when compared to control (untreated) in the testosterone-stimulated castrated intact male rats. Hence, the pro-androgenic effect as shown by this study further supported the traditional use of this plant as an aphrodisiac.

Interesting study...i also heard and read that tongkat should NOT BE used during PCT...but rather during the last part of your cycle...similar to HCG ....


Any other comments?

[GetBiggg]

that's interesting.. I was planning on running mine during PCT - any truth to what tcw just stated?

[FlyByU]

Yes it's true. Tongkat ali is suppressive to pituitary LH just like HCG , since it works in the same manner. Only use during cycle.

[GetBiggg]

interesting.. so should I run it the last month or so of my cycle?

[Maetenloch]

Yes it's true. Tongkat ali is suppressive to pituitary LH just like HCG, since it works in the same manner. Only use during cycle.

Just curious if there are any studies showing this? All I've seen are ones showing that tongkat ali may have LH-like properties. Others suggest that it lowers SHBG.

[GetBiggg]

anyone...? i'm curious for some answers // studies on tongkat ali.

[ShnouzedUp]

holy smokes.. im glad i saw this, cause i was plannin on runnin tongkat in my pct as well..... BUMP for more info!

[Sharky72]

Ive been running it since my last shot 8 wks ago and I love the stuff.

[GetBiggg]

I think i'm going ot try running it for a week at 100mg ED and see if it has any effects and save the rest of it for PCT like i was planning on doing anyways.. I have two months worth of the stuff anyways.

[trulbfan3]

after my first "and only" cycle i ran out of clomid during pct "it got soaked and disolved in my gym bag" i was havin problems w/ things working correctly and after 2 days of tongkat and tribulus i was just as horny as i was on test. after about 2 weeeks of taking it everything seems to be back to normal.

[GetBiggg]

what doses of each tonkat and trib were you running?

[trulbfan3]

1600 mg of each a day. they were combined in the same pills. 2 pills had 800 mg of each a day and i was taking for pills a day. there was something else in them too but i cant remember what right now. i have the bottle at home and i wll list the ingredients. i think its called sumthing like 3-test

[trulbfan3]

i know after the second day of taking it i went from barealy being able to get it up much less keeping it there , to bangin the ole ladt four times in won night. total for 61/2 hours and i still didnt have enough. she was just too sore for more.

[GetBiggg]

Zinc (sulphate) 20 mg
Magnesium (as oxide) 20 mg

Tribulus Terrestris (45% saponis) 500 mg †
Avena Sativa (stem) 500 mg †

Yes it's true. Tongkat ali is suppressive to pituitary LH just like HCG, since it works in the same manner. Only use during cycle.

I have always used Redkat during pct because I was always told that it was not suppressive. We need some confirmation here, you must be thinking of Tribulis.

[FlyByU]

No tribulus is junk imo. Tongkat is suppressive to pituitary LH, so will keep you suppressed for longer. It may help boost your libiod during pct, but that's because you are supplying your body with a LH analogue (tongkat).
Blood tests carried out by Serge Kreutz confirmed that tongkat ali boosts testosterone , but suppresses LH.

[FlyByU]

Btw, if you think Redkat tongkat ali is good, you will be blown away by the tongkat ali found on tongkatali.org. You can find it cheaper on ebay. I use the CCM brand, which is the same stuff as on tongkatali.org but much cheaper.

[GetBiggg]

i'm still confused - can anyone else back this up... ?

if this is true, then I shold run this during cycle instead of pct right?

[DirtyDog7]

I'd like to know more too!

[FlyByU]

Yes, take it during your cycle to prevent nut shrinkage. Don't use it post cycle!

[GetBiggg]

why not use it during post cycle - are you saying that it cuases further inhibition of natural test production?

[FlyByU]

Yes! I thought I made that pretty clear.
