The ultimate would be a blend of acetyl-l-carnitine, glycine propionyl-l-carnitine, and acetyl-l-carnitine arginate.![]()
What? How?Bad idea. ALC and PLC taken together reduce each other effects.
Yes, the "Ubiquinol" bump! We'll keep at it! DUbiquinol
What? How?

OBJECTIVES: We compared the effects of acetylcarnitine, propionylcarnitine and both compounds on the symptoms of chronic fatigue syndrome (CFS). METHODS: In an open, randomized fashion we compared 2 g/d acetyl-L-carnitine, 2 g/d propionyl-L-carnitine, and its combination in 3 groups of 30 CFS patients during 24 weeks. Effects were rated by clinical global impression of change. Secondary endpoints were the Multidimensional Fatigue Inventory, McGill Pain Questionnaire, and the Stroop attention concentration test. Scores were assessed 8 weeks before treatment; at randomization; after 8, 16, and 24 weeks of treatment; and 2 weeks later. RESULTS: Clinical global impression of change after treatment showed considerable improvement in 59% of the patients in the acetylcarnitine group and 63% in the propionylcarnitine group, but less in the acetylcarnitine plus propionylcarnitine group (37%). Acetylcarnitine significantly improved mental fatigue (p =.015) and propionylcarnitine improved general fatigue (p =.004). Attention concentration improved in all groups, whereas pain complaints did not decrease in any group. Two weeks after treatment, worsening of fatigue was experienced by 52%, 50%, and 37% in the acetylcarnitine, propionylcarnitine, and combined group, respectively. In the acetylcarnitine group, but not in the other groups, the changes in plasma carnitine levels correlated with clinical improvement. CONCLUSIONS: Acetylcarnitine and propionylcarnitine showed beneficial effect on fatigue and attention concentration. Less improvement was found by the combined treatment. Acetylcarnitine had main effect on mental fatigue and propionylcarnitine on general fatigue.
Possible reasons why:
The CGI improved in the ALC and the PLC group, but not significantly in the ALC+PLC group, likely because of the higher total carnitine ester dose and indicating an inversed U-form dose–response curve.
The effect of ALC on mental fatigue and attention concentration was significant. The PLC group showed most improvement in general and physical fatigue and slightly less in attention concentration. The ALC+PLC group improved very well on general fatigue and also, but not significantly, on physical and mental fatigue.
I am familiar with this study. The compounds successfully address different areas. I fail to see evidence that the two compounds contradict each other when administered simultaneously. As it turns out, the results probably suggest the existence of some type of diminishing returns as the amount of carnitine esters used increases.
First, of all, we are talking about a limited example, CFS, and not a broad number of cases confirming that thesis. Second, the compounds appeared to be effective in different aspects of CFS, in line with expectations. Third, the research suggests the presence of diminishing returns in the action of carnitine esters, a plausible conclusion, rather than an antagonism between the two carnitine forms, per se. Fourth, we cannot reach general conclusions based on the results of one study alone. Fifth, the only widely recognized scientific gold standard in clinical trials are double-blind, randomized, placebo-controlled studies! As far as I can see, the study you rely on does not meet these exact requirements, so it would be a major leap of faith to accept its inconclusive suggestions as the ultimate truth. I did not want to take the discussion this far, but c'est la vie!Neuron; said:It shows combining the 2 resulted in being less effective than taking either apart. If you see any reason for combining the 2 and research supporting such use please post it.

I am not sure I completely understand your comment, but my position is still that acetyl-l-carnitine hcl, (glycine) propionyl-l-carnitine, and acetyl-l-carnitine-arginate will make a great mix. One might probably have to add a universal (fat-and-water-soluble) antioxidant such as an alpha-lipoic-acid form to address possible elevations in free-radical activity due to a potential boost in mitochondrial action.Neuron; said:No I agree with you hence my "At least in CFS statement". With your statement said there is no reason to combine those 2 compounds that has been proven. Thus one must review the research and decide which compound they feel they will benefit from more.

We have come full cycle to post #1854! I know NA-RALA is the most advanced and stable form of ALA around. I deliberately generalized my reference to ALA.Neuron; said:What's your position based on? Do you have any studies supporting your view? Why would you combine ALC and ALCA together?
If you're going to use lipoic acid NA or K R-Lipoic would be the only forms I would recommend.
Ubiquinol
What? How?Bad idea. ALC and PLC taken together reduce each other effects.
See post #1861 above!They do in chronic fatique syndrome:
Invalid Link Removed
We used to have it laballed Testofen, but we relabelled it as Invalid Link RemovedIDS Testofen X/Bulk Testofen powder
how about some egg white company to sell there stuff on here? like eggoilogy or international egg whites?
x2Bioperine 5mg tablets/capsules.
LEF have been promoting this combination. In their words "With the discovery of acetyl-L-carnitine arginate, the benefits of acetyl-L-carnitine can now be greatly augmented."What's your position based on? Do you have any studies supporting your view? Why would you combine ALC and ALCA together?
Dinoiii made quite a convincing argument to the contrary at bb.com recently.If you're going to use lipoic acid NA or K R-Lipoic would be the only forms I would recommend.
The 1st will be done, and the last is possibility.May be these have already been requested in which this is just a reminder, otherwise could you please carry :
Banaba extract (20 % corosolic acid) powder
Tyramine powder
7-hydroxy DHEA powder
Two nice compounds!...Resveratol and Idebenone...
We used to have it laballed Testofen, but we relabelled it as Invalid Link Removed
Guys thank you for all the suggestions and keep them coming. Things don't happen instantly, but your suggestions DO get the ball rolling! Keep it up :clap2:
how about good cholesterol caps? HDL in a capsule. most prohormones decrease HDL, some steroids do. you need HDL to build muscle even if you're natural - lots of people don't like eggs, and nobody sells HDL....
NOW's Policonsanol is very inexpensive and a great supplement in general.Or perhaps just start carrying Policosanol![]()
