Thank you all for your information. I'd be lieing if I said I'm not concerned about my continued use of this sports supplement. I have heard of protein powders causing chaos for the kidneys before, and I REALLY do not want to end up with some kind of problem with my internals later in life (just turned 27). The supplement has helped me pack on muscle noticeably in just 2 weeks of use, and I'd like to continue using it throughout the summer as I progress up the scale of leading a more and more physically demanding lifestyle, having been on a long period of rest after a form of distrophy in my foot, and ligament damage in my knee. I'm not the greatest of cooks, my weekly menu could sure use some more variety, but I do cook salmon, tuna steaks, chicken breast fairly regularly.
But despite these staple protein providers (eaten as an evening meal, often long after training), I didn't get anywhere near the results I've had by drinking a 'muscle builder' shake minutes after the gym.
OK this isn't a nutrion site, so I won't bleet on and on. I appreciate the confirmation that as long as I stay on the straight an narrow (would never consider any type of steroid) I will not be likely to run into any kind of trouble at my initial medical.
I am a bit concerned though about my continued use of these things...getting through this 1200g tub pretty darn quick, will have to look for a replacement soon, think I'm gonna stay away from Internet sellers though having read your contribution Track and Field, thanks for the heads up
