    Is Creapure brand Creatine worth it anymore?

    Thank you. I've used bulksupplements for a while, but I've always been skeptical of the safety of their products.

    Is Creapure brand Creatine worth it anymore?

    It seems that some of the brands, such as Optimum Nutrition, no longer use Creapure in their Creatine powder. I was about to buy some, but read comments on Amazon stating that they pulled a switch. I'm looking for something reasonably priced that's also good quality. This is the cheapest I could...

    What supplements would cause high AST or ALT?

    I hope you're right, because I like it. I'll re-test after a while to see if it was the exercise.

    What supplements would cause high AST or ALT?

    I just retested after stopping most of my supplements. AST 21, ALT 22. I still don't know if it was the exercise or the L-Citrulline. I felt better while one it, so I might try again.

It's just a bag of powder from China. Most of the reviews you see are because Bulk Supplements offered a free sample of another...

    What supplements would cause high AST or ALT?

    That's the conclusion I came to, but I'll contact the doctor tomorrow and get his opinion. The trainer pushed me hard exactly 5 days before the test. This website has a graph that shows AST and ALT levels close to their peak around 4-5 days after strenuous exercise...

    What supplements would cause high AST or ALT?

    I'm really freaked out right now, because it's Saturday night and I have no doctor to contact. My Quest Lab results just came back. My AST is 95, and my ALT is 66. Back in April my AST was 21, and ALT was 27. I'm overweight, but I rarely drink. Very rarely. The same day (evening) after my test...
