Hi All,
What’s your opinion on herbal testosterone boosters in addition to standard PCT? Do many of you incorporate additional supps to aid recovery - how do they assist (if at all) from your experiences?
I’ve tried using Tongkat Ali / Tribulus extract / MACA / Avena Sativa etc and have read a lot of the hype around how they work. I “think” I noticed an increase in sex drive during my course of Tongkat but can’t back this up with blood tests.
I’ve found the following "studies":
Data from Independent Study of 5 Healthy Men, San Francisco, CA
Dosage: 100 mg twice a day for 10 days
Testosterone test type - Saliva
Volunteer.Age.Pre-treatment ng/dl blood.After Treatment ng/dl blood
1............26...860/30..........................1650/50
2............35...875/40..........................1576/60
3............42...650/20...........................875/30
4............52...450/25...........................765/35
5............24...950/45..........................2210/55
Participants showed a significant increase over 10 days in serum testosterone level.

Another study, this time from a more reputable source:
Effects of Eurycoma longifolia jack on laevator ani muscle in both uncastrated and testosterone-stimulated castrated intact male rats.

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.

Does anyone know of any other formal studies where these supps (particularly Tongkat) have been properly tested? Has anyone had real libido increases through using supps such as Unleashed (Protein Factory), which I think is meant to reduce SHBG?
Cheers,
