I am on my 8th bottle of jacked. I was a user of pslin. When on carbs. I have used4 bottles and just recently bought another 3 bottles of and tna. The reason I would love to log it is I can measure my before base line test numbers and after numbers. I get free blood work so I am not worried. If this product is truely legit numbers will speak for it's self and I will scan and post my results. Not to mention I was going to start tna but can wait for this.
