I was on musclechatroom and read good comments about Acetyl-L-Carnitine by Dr.Chrysler.He said it can stimulate LH production and I alos found pubmed study. Note in the study LH <3 IU/L referred as hypo. we are mostly LH<3.
I request all post fin user who have taken ALC please post their experience here.

Several neuroendocrine disregulations have been demonstrated in patients with hypothalamic amenorrhea, but a definite therapeutic strategy has not yet been found. Since acetyl-l-carnitine (ALC) has been reported to have a specific effect on central cholinergic, serotoninergic, dopaminergic and opioidergic systems, 20 patients with hypothalamic amenorrhea were treated with ALC (2 g/day, per os). Both the clinical efficacy and the endocrine parameters were evaluated after 6 months. The patients were subdivided in two groups according to their LH plasma levels: A) hypogonadotropic: 10 subjects with plasma LH less than 3 mIU/ml, and B) normogonadotropic: 10 subjects with plasma LH greater than 3 mIU/ml. All subjects underwent: 1) a pulsatility study (4 h sampling every 10 min), 2) GnRH test (two bolus injections of 10 micrograms at time 0 and +120), 3) TRH test (200 micrograms). These parameters were evaluated before and after 6 months of ALC administration. The occurrence of a spontaneous menstruation was observed in 6 out of 10 hypogonadotropinemic and in 4 out of 10 normogonadotropinemic patients. Menstrual bleeding occurred between the 3rd and the 6th month of therapy. Major hormonal changes after ALC administration were observed in the hypogonadotropic subjects. They showed a significant increase in baseline plasma LH levels (from 0.9 +/- 0.1 to 3.5 +/- 0.7 mIU/ml, p less than 0.05) (mean +/- SEM), a significant increase in LH pulse amplitude (p less than 0.01) with no changes in LH pulse frequency, and a significantly increased response of LH to the latter GnRH bolus during the GnRH test. Hypogonadotropic patients also showed a significant increase in both estradiol (from 18.8 +/- 2.5 to 48 +/- 3.3 pg/ml, p less than 0.05) and PRL (from 6 +/- 1 to 11.4 +/- 1.7 ng/ml, p less than 0.05). No significant differences were observed in the hormonal parameters of normogonadotropic patients after 6 months of ALC therapy.(ABSTRACT TRUNCATED AT 250 WORDS)
