Back at the Arnold Classic in Columbus Ohio we got word that MHP may be changing the name of their nighttime recovery supplement 4D Tropin. It was not a guaranteed change but something that was likely and important to us since we had high hopes for the product. We can’t actually say had highs hopes anymore as we have actually finished off our tub of 4D Tropin and will be dropping the extremely interesting review of the supplement very soon. Getting back on topic and as you can see above, MHP have followed through on possibly changing the name of 4D Tropin officially moving to 5D Tropin. Nothing of course has been done to the formula with everything remaining the same from ingredients and doses to flavor and size. MHP’s own website has yet to reflect the update however it is only an image and a few mentions that will need to be edited. Not many other locations are actually stocking 4D Tropin just yet, so their first lot may be 5D Tropin meaning no re-educating for customers. When our review does eventually surface in hopefully a few days time do forgive us for the confusion as although our bottle is branded 4D Tropin, we will refer to it and title the review as 5D Tropin.
