Its most likely "roughly" 1-2 grams because different batches of it come out at different purities. So even though you may measure out exactly 2 grams of powder, you may only actually be getting 1g of CEE, or you may be getting 1.9g...Thats why you should buy from bulknutrition.com because they mearsure each batch and tell you how much pure CEE you actually get per 1/4tsp.
