It's a powerful supplement to prevent mineral deficiencies. That's my main reason behind taking it. I first tried it in 2020 while abroad but didn't take ii beyond a month. Actually, I was swallowing the powder and chugging water after it (lol) instead of mixing it with water, or coffee etc. Stupid of me. Used to almost puke each time. So, I ordered it again after getting wiser :) Product arrived within 45 days (India) via normal post. Fortunately, no custom charges were levied. The first few times I took it, it gave me slight buzz and mild/moderate focus for an hour or so. I guess it was because of some deficiencies which have been addressed as I no longer feel that kinda thing. I take it on empty stomach (usually) in water or with cold coffee. I also started taking COQ10 as it is supposed to work synergistically with shilajit for optimum mitochondrial function. The powder hasn't clumped considering the hot and humid weather right now. One interesting thing is I recently started taking 10mg pregnenolone by some other brand three times per week and 25mg DHEA once per week. My mood, drive, emotional discipline, focus has improved greatly. I feel like I'm my 14yr old self again in terms of those things. Not to mention, libido seems to have shot up. I have ordered ND's pregnenolone as well as they mention that Tongkat ali is and pregnenolone taken together work for testosterone production. Hence, I think Shilajit + pregnenolone are doing the same thing for me. Although, I was also taking some left over Tongkat ali tabs. I'm also taking some Shoden Ashwagandha thrice per week to reduce stress. So that may also be one of the factors. I"m sorry for deviating in the end lol. Thanks for everything ND!!
