No idea about the fancy shit youre taking.
About the second question. Naturally? You can try binge drinking regularly. Consuming mass quantities of refined soy products. Consume heavy metals. Smoke pot constantly.
But a safer and more effective method would be to inject testosterone for about 4 weeks. Then wait a few more weeks as the level of the drug fall. The idea would be to suppress your own production then get your T level tested as your natural production is suppressed but also after much of the injected drug has cleared the system. Obviously not a natural approach though.
