Tried Synthetix5 purchased from shop in So Cal town. Paid 25 bucks, cheap since Ive heard other brands go for around 40.

Took the test, got a call back next business day saying the sample was diluted.

This was after reading the posts on this site with other members saying they had issues with this brand.

Now being forced to retake test. Not sure if it will be observed.

My advice for those looking into Synthetix, pay the extra flow and get Quick Fix or Magnum brand. If not available find another shop.
