Let me know how your order from grindstone works out, as I had ordered from them but didn’t have a good experience. I had emailed with one question before the order (shipping options), and got no reply. I sent it again, no reply, but regardless I still placed an order for 1oz of tadafinal, and asked another question (what the liquid suspension was composed of - water, alcohol, or glycerin base), but no answer. Then I got my order with the powder at the bottom, not dissolved at all (Which is fine just shake for 15 seconds). I tried 1 dropper day one, and noticed nothing (and I’m familiar with what to expect). The next evening I doubled to two droppers, and nothing, and at this point I emailed them again just asking ‘did I get the right item from you?’, but no response. The next time I tried 5 droppers, and finally one evening, half the bottle, and only then do I ‘think’ I had its effects, but by then the bottle was 25% empty. I sent one final email, nothing rude or negative, just that I felt disappointed I never got emails from them, and that I was not even sure I got the right item, and left it at that.
So I look forward to hear how it worked for you from them, as I did not have a positive experience I was hoping for, considering they are priced well. I always have told myself, if a company doesn’t answer a simple question email, then do not order from them, but this was the one time I tricked myself.
