Testosterone Booster?

[grasshopper]

What is the strongest over the counter test booster? Not necisarily for PCT but something that can be used year round. Would I be better off using Cyclofenil year round?

I haven't looked at Cyclofenil, but IMO, the ones that work all have negative effects that probably outweigh the positives in the long run. Stuff like ATD (Novedex XT) lowers GH levels by 50% for example. Then there's potential libido problems, problems adjusting once you finally get off etc.

I haven't seen proof that any of the herbals actually work. Tribestan was recently shown not to work in a Bulgarian study.

IMHO...There is none.

the herb MACA works but you have to take at least 3000-5000mg a day. Also keep in mind you can if you research get this herb dirt cheap and you may have to be on it for 6 weeks to get full effect. The nice thing is women can take this as well to help balance their system as well

Where did you get the info that ATD lowers gh 50%? Never heard that, was this shown in a study?

Yes, this one:

Willoughby D. S., & Wilborn C. Eight weeks of
aromatase inhibition using the nutritional supplement Novedex XT: Effects on serum steroid hormones, body composition, and clinical safety markers in young, eugonadal males. International Journal of Sports Nutrition and Exercise Metabolism.


It's on Gaspari's site.

It looks like the numbers are within the margin of error.

Data are means ± standard deviations. No significant differences were observed between groups throughout the 11-week study for and of the hormones variables included above (p > 0.05).

Well, the researchers themselves think this GH lowring effects might be why there was no increase in LBM. From the study:

E2 inhibits IGF-1 and might attenuate the circulating IGF-1 responses to GH (9), primarily based on the premise that estrogen might down-regulate hepatic GH receptors, alter the hypathopituitary–adrenal axis (HPTA), and impede tissue responsiveness to GH (16). In light of this, we were interested in determining the effects of Novedex XT supplementation on serum GH and cortisol. For the placebo and Novedex groups, we observed no changes in serum cortisol; although not significant, over the course of the supplementation period there was an average 45% decrease in serum GH in the Novedex group. Although we did not measure
serum IGF-1, in the context of incomplete inhibition of aromatase activity with Novedex XT, it is plausible that the suppression in the HPTA and potential GH-receptor down-regulation might have affected the hepatic release of IGF-1, thereby possibly negating any observable increases in fat-free mass. This assumption can be partly supported by previous data showing that complete E2 suppression with anastrozole had no effect on serum GH but decreased IGF-1 (16) and that a 38% suppression of E2 with exemestane had no effect on IGF-1 (15).

Interesting info killerstack. Makes one think twice about using atd as an anti-e / pct. I will have to look for more info on this. Nolvadex-xt also has other ingredients in addition to atd, not sure if they play any role in this.
