In the sprint study 62 stands for the correlation coefficient not the change in DHT. In the sprint study it says: ± at baseline, ± pg/μg protein, are you sure that the numbers are baseline and then post training? If that is the case I think they should have expressed it a bit clearer in the study instead of saying baseline, pg/ug protein, at first I interpreted it like it was first serum levels of dht, then tissue levels of dht or something because the units are only mentioned in the post training levels of dht and not in the baseline levels, if I have interpreted it correctly.
Pumpkin seed oil has also been proven to inhibit the production of 5-alpha-reductase. Pumpkin seeds contain not one but two DHT blockers. The first is beta-sitosterol, a phytosterol, which is structurally like cholesterol. The other is a steroid, delta-7-sterine. A 2014 Chinese study evaluated the effect of a daily dose of 400mg of pumpkin seed oil on 38 men with AGA. A randomized equal number of men received a placebo. After 24 weeks, scientists discovered a 40% mean increase in hair count in the group receiving the pumpkin seed oil as compared to the placebo group.
