I've stated this before and say it again: if you're a UK resident (probably non-US for that fact) then unless you are pretty flush Biotest supplements are not affordable for the average Joe.
On the plus side, the UK has a fabulous online supplier called My Protein offering an array of stuff - including single amino acids and proteins, e.g. leucine, glycine, beta alanine, etc, as well stuff like whey hydro. They are also sole UK supplier of Pepto-Pro (casein hydro). This has allowed me to devise my own peri-WO formulas at a fraction of the price of any branded supplement, Biotest included. They also offer a range of health supplements like liquid fish oil, high potency vit D, trans-resveratrol, etc, again at very competitive rates, so UK-based folks are quite fortunate after all!
