Best no propylene glycol liquid minoxidil

[proactive]

Hey all I am on the big 3 at the moment (dutasteride instead of finasteride) but I had to switch to foam rogaine 5% (rogaine name brand) because liquid rogaine 5% (kirkland) was irritating my scalp. My question to you guys is there any reputable no propylene glycol liquid minoxidil. I ask because I would like to be able to use liquid rogaine when my hair gets longer. I have checked out sets such as minoxidil max and xandrox and it is hard to now which would be the best site to order from. It seems to me that minoxidil max has the most endorsement from this forum, but I would like peoples updated views on the best source of no propylene glycol liquid minoxidil
