is Minoxidil "Sulfate" really 14x stronger than regular minoxidil?

[Zmay1962]

I am new to this forum. This my first post. Hello everybody : )

I have used (Kirkland) minoxidil topical in the past with not that great of results after about 18 months worth of use. I am a middle aged female that has recently had a face-lift which pulled my hairline back, plus my hair is thinning....

Pubmed did a clinical study that claims that the sulfated version works exponentially stronger than regular minoxidil, 14x is what is stated in the study.

Has anyone tried a minoxidil sulfate topical? If not, would anyone have any info or insight or thoughts about minoxidil sulfate?

Surprisingly, I only found one seller selling it on an auction site.

If it is really stronger, shouldn't there be more formulations or different brands available for retail purchase?

I'm tempted to buy some, but would like to get any comments or thoughts about it.

Thanks in advance for any help : )
