So the recommended dose by All Saints sounds legit. They say to use 2 globules of 5 drops two times a day. This is 20 drops. One mL is 20 drops. The solution is 12% so that’s 120 mg/day, assuming all gets absorbed. That’s the lowest dose used by Kunelius et al. (https://www.ncbi.nlm.nih.gov/pubmed/11932266)
For reference, these elderly men had an average DHT of 1.5 nmol/L before treatment and 9 nmol/L after, so DHT rose 6 times (some required a double dose, or 250 mg/d for an equivalent effect).
My DHT is 175 pg/ml (300-850) which is 0.60 nmol/L. A x6 increase will put me at 1050 pg/ml or 3.6 nmol/L. That’s the maximum expected increase, if I am like the high responders in the paper.
Note the decrease in all other hormones after treatment - T, E2, SHBG, FSH, LH. My free T is very high – 29 pg/ml (7.0 - 22.7) – so a decrease might be good.
