Dosage check

The dosage check compares the amount you plan to use with our shop's advice. You pick a product, enter your age and your amount per use, and immediately see whether you are within our advice, below it, or above it.

Under 'Best choice' you see the amount we recommend most. 'No more than' is the maximum we consider responsible. Below it you see your own amount, so you can see at a glance where you stand.

No. It is harm-reduction information in our own words, not medical care or a prescription. Use only if you are 18 or older, and use responsibly. If you feel unwell, seek real help.

Start low and take your body weight, your tolerance and whether you use alone or with others into account. In doubt, choose the lower end of the range. For research chemicals we give no dosage, because they are not for consumption.

Our advice is matched to the products we sell ourselves, in plain language and with concrete numbers. That way the advice fits what you find in our shop, with no external references.
