@Creatineman how did it go with Creatine-Alpha-Ketoglutarate? I'm looking forward to hearing about your experience!

It did nothing.

There is actually as second creatine transporter but it seems to be synthesized only in the retina.

There are also paralog genes where things get more complicated:
http://www.sciencedirect.com/science/ar ... 191301367X

Regarding the functioning of the transporter, the type of mutation does not easily correlate with the phenotype. For example, even a large deletion does not mean a severe phenotype and small mutations can be lethal to the entire transporter. For example, one base pair mutation may end up encoding an end of gene signal if in the right location. I suspect you're on to something though. It is possible that in some cases that go undetected, a partial transporter may lead to learning impairments that are not severe and definitely no seizures.

Have you seen this paper on fenugreek's effects on how the creatine is assimilated? I've been meaning to try it with monohydrate or glutamate but we're still having difficulties with administering the base formula for supplements

Interesting thanks for those links. There is another creatine transporter in testis also

http://www.sciencedirect.com/science/ar ... 4396902542

There is a mild case of the transport defect here

http://onlinelibrary.wiley.com/doi/10.1 ... 480.x/full

We identified a 3-year-old male with CRTR deficiency referred for study owing to mild psychomotor retardation with independent walking acquired at 18 months and expressive language impairment. He never experienced epileptic seizures. Clinical examination revealed clumsiness in his gait and subtly abnormal hand movements.

After reviewing the clinical description of seven cases under the age of 4 years diagnosed previously,7,10,11,14,15 we conclude that our patient has a mild presentation of this condition with late-onset walking and no seizures or autistic behaviour

Lipoic acid increases creatine uptake also

https://www.ncbi.nlm.nih.gov/pubmed/14669930

I took both ALA, and fenugreek with no effects. Maybe AlA, and fenugreek only work in a normal person with functioning creatine transporters.

Still have not got test results yet.
It is possible to make home made liposomal creatine. The instructions to make liposomal vitamin c are here http://qualityliposomalc.com/ just replace vitamin c with creatine monohydrate.

Creatineman, what are your thoughts and have you tried any PCr-Mg-complex? Some papers speculate that this might bypass the CRT1 transporter.

I tried magnesium creatine chelate for a while which is a chelate like what you mentioned but it didn't do anything. I don't know where to get the on you said. I doubt manufacturers would have it on hand.

After trying liposomal creatine monohydrate, anhydrous, and phosphate I have concluded they are impossible to make due to the high pH needed to make them stable which drives down the transition temperature of phospholipids, and also might be dangerous, and for the creatine phosphate the amount of sodium it puts in the mix which causes diarrhoea. Trying transdermal tokkyo nutrition deca creatine which contains creatine decanoate. The minimum order quantity for creatine decanoate from suppliers on ali baba is 100kg ):

Creatine amide leucine would probably work in this http://www.getrippednutrition.com/VPX_C ... m?CartID=1
however VPX stopped making it which means the body building shops that have some left over will eventually run out, and no manufacturers make it so then it would be back to square one.
