This is 500g of Citrulline Malate powder. I bought too much, so I'm offering it at the lowest price. It promotes blood flow and pumps you up, making it ideal as a pre-workout supplement before weight training. Even on days you don't work out, taking it after every meal can improve metabolism and promote growth hormone secretion. Expiration date: April 2026 If you'd like to buy in bulk, I can offer an even lower price, so please feel free to comment.
