Please note: Part 2 has been rebranded to "Universal", so we now have Complete (Part 1) and Universal (Part 2). Depending on stock availability, the Part 2 bottle you receive may say either Complete or Universal - please rest assured it is the same formula, and we'll update everything to reflect this change once we've sold out of the Complete stock and just have Universal.
