Exactly. You get a test boost but once it aromatizes to estrogen you're going to look rather soft. Basically the hormonal balance is skewed in favour of elevated estrogen levels. I've run a number of solo SERM cycles in the past and do feel peak testosterone levels offer a slight boost (I don't have low test) but you will want to run an AI alongside and it's a matter of trial and error to get the dose right. I find Exemestane at 12.5mg E3D kept the estrogen sides at bay. All in all I don't bother anymore given all the fuss and expense in order to gain a little more strength in a given time frame than usual. If you want to go down the PED route and run something non-suppressive I would recommend MK677. It has helped me recomp but needs to be run longer term (a few months) to see results.
