On the role of dihydrotestosterone in regulating luteinizing hormone secretion in man. - PubMed - NCBI

From this study, it shows that DHT supplementation (and this is direct DHT, even "theoretically" more suppressive than a pro-hormone) has little affect on LH (luteinizing hormone) in males. This study had individuals with 8-10 times the normal plasma DHT level for three months, with little to no change in LH values.

Thought this info could be helpful to those here concerned with "suppressing themselves again" or "crashing their T" with the prohormones suggested here.
