If the description for the Advanced Protein sounds like Low-Carb Grow!, then I would use it. Grow! at one time was named Advanced Protein here in the States.
As for the RED KAT, from the T-Nation Store, has 72 capsules with a dosage of 1-2 capsules in the morning then the same dosage a few hours later. Just divide the total number of capsules by how many you’ll take in a day to find out how many bottles you’ll need for the month. Take into consideration the dosage cycling as well (you’ll only need approximately 20 days worth of product).
google for “workoutworld shop” and get Low-Carb Grow! and ne of the Biotest products from them, i live in croydon in south london and get any Biotest product i want from there
