I wouldn't drink it and if you drank 1ml it would be 50 mg of minoxidil not 5 mg. plus you would be stomaching pg ethanol retinol all kinds of dangerous additives , it would be easy to get the pills. They are quite cheap at qhi.co.uk
How hard is it to visually divide 1 ml into 5 parts? Not hard. That would be a 5mg dose, assuming 5 grams in one 100 ml bottle. ...
Ethanol has a j curve for morbitity. 1/10th of ml ethanol is insignificant. Also, there is such a thing as hormesis:

The acute oral toxicity of propylene glycol is very low.
Serious toxicity generally occurs at plasma concentrations over 4 g/L, which requires extremely high intake over a relatively short period of time, or when used as a vehicle for drugs or vitamins given intravenously or orally.
[25] It would be nearly impossible to reach toxic levels by consuming foods or supplements, which contain at most 1 g/kg of PG, except for alcoholic beverages which are allowed 5 percent = 50g/kg.
[26] Cases of propylene glycol poisoning are usually related to either inappropriate intravenous administration or accidental ingestion of large quantities by children.
[27...
The potential for long-term oral toxicity is also low. In one study, in 1972, 12 rats were provided with feed containing as much as 5% PG over a period of 2 years, and showed no apparent ill effects; no data on offspring were offered.
[28]Because of its low chronic oral toxicity, propylene glycol was classified by the U. S.
Food and Drug Administration as "
generally recognized as safe" (GRAS) for use as a direct
food additive, including frozen foods such as
ice cream and
frozen desserts.
