In a double-blind, randomized, placebo-controlled trial, healthy young men supplemented their diets with either placebo or PS. 46 Compared to the lack of effect of placebo, 10 days of dietary supplementation with PS significantly suppressed the cycling-induced elevations in serum cortisol concentrations that were apparent in the men in the placebo group. In addition, pre-exercise serum total testosterone concentrations were on average 37 percent greater, and pre-exercise serum cortisol concentrations were on average 35 percent lower, after just 10 days of PS supplementation.
I think this approach is fine. I must say having been doing this for years, treating hundreds and thousands of men I have been underwhelmed with the results with topicals. Injections can cause peaks and valley and I have many younger men inject twice a week that smooths out the peaks and valleys. I think it is appropriate to follow the advice of your primary doctor and endocrinologist. I have just seen too many men spend months or years with gels with sub optimal results. Many men are diagnosed with depression and are not really depressed (I have no idea if this applies to you), but the presumed depression is base dupon low T.
My recommendation would be to pursue this but if a few months pass and results are modest consider another approach. Pellets are one approach to have smooth levels of T and are placed every 4 months.
