I bought a 120 30mg bottle from Nootropics depot thinking that it would last me 120 days but I decided to double my dosage by taking 30mg in the morning afternoon and another 30mg in the evening.
Although it gives a bit of focus energy, I don't find it "keep me awake" stimulating but after working a 10 hour day I find myself easily taking care of financial matters in my trading accounts that take focused brain power with ease and not wanting to veg out watching YouTube MMA videos.
Saffron is currently getting 2 thumbs up from yours truly.
