And yes, layering is the ultimate and most versatile of making, testing then fine tuning a mix but for simply adding A1 to an existing product in order to make it portable and practical for going out etc, then mixing in a Togo is still quite acceptable, it’s not wrong and won’t spoil anything.
Don’t mix 30mls worth until you find what’s effective for you as you the potential for a lot of wasted product is too high.
