Granted, you’re not planning on daily use. But I have a suspicion that acute increases seen with naltrexone may be like those seen with, for example, arginine: timing is changed, which can result in an acute (brief) increase, but not total output over a more extended time.
I’d consider GHRP-6 instead.
Good SAMe is expensive. Now I haven’t done specific research to be sure that there isn’t anything that SAMe will do that TMG won’t, but in general anyway TMG serves the same purpose and costs a lot less money.
Narcotics decrease testosterone and increase GH, so naltrexone could have the opposite effect.
Anyway, that stuff seems nasty, I woulnd’t mess with it. It is interesting though, how common neurotransmitters like glutamate and gaba modulate sex hormone output.
And, as Bill Roberts said, you would have to be constantly on it for it to have an effect. Even if it has an effect, the increase in testosterone or LH might be so small that it wouldnt be worth it.
@ Bill – I appreciate your input and thanks for the study, i hadn’t even considered the posibility of lessend GH secretion. I use a GHRP on most cycles and IGF in PCT so maybe that will compensate(?) as i’m keen to give this a try.
@ Lover – i appreciate your efforts in trying to look into this for me… but since you love pubmed so much, here is a free full text one for ya…
