5/5
I want to start by echoing a previous review that this is more of an endurance product rather than a muscle-building product (my experience). This really comes as no surprise given the myriad of benefits that (-)epicatechin provides, specifically those related to blood flow.
So I picked up a bottle of the TD version last year when it was first unleashed (yeah I went there) on the world. About a week into the run (1 pump rest days, 2 pumps workout days) I noticed a somewhat sudden and tremendous endurance boost that turned my gym session into a nearly nonstop circuit training routine. As soon as I finished up a set I felt like I was ready to go again ~30 seconds later, and I usually did. Time between sets dropped like a rock, number of sets went up, and number of exercises per session went up. This endurance boost carried over into my running as well and was maintained for the remainder of the bottle. Truly felt superhuman for a brief span there. At the time this was very unexpected for me, though very welcomed, as this was marketed as a muscle-building supplement due to its myostatin inhibiting properties (still not sold on this property translating to real-world muscle building). However, the crazy stamina boost most definitely aided, somewhat indirectly, in building strength and muscle because of the extra reps/sets and intensity I was fitting in to my routine. As much as I enjoyed the run the price made it prohibitive for me to continue using as a staple supplement, though it had definitely earned a place in my "will use again" bag of supps. A week or so later I was back to my normal non-superhuman training sessions (note: I tried VERY hard to keep up the fast-paced training but was unable to do so without quickly tiring myself, placebo effect be damned).
Fast forward to today where I am once again 1 week in to a bottle of TD EP1C Unleashed (picked up quite a few bottles during the AWESOME sale Olympus Labs put on at the end of December - thanks OL!), and once again the endurance boost shows up and hits me like a TRUCK. Seriously had an incredible workout this morning - went in to do deadlifts and traps, ended up doing deadlifts and a FULL back&bi's routine...then felt good enough to run a quick 5k an hour later. Glad I stocked up this stuff
Worth noting is that the bottle I had last year was VERY runny, almost like water, which made it kind of annoying to apply. They seem to have corrected this as it now a much better consistency. Still smells good and dries just as quickly.
TD EP1C Unleashed is the real deal and absolutely blows away the previous epicatechin supplements I have tried in the past. Olympus Labs has a real winner here, one of the very few supplements I've tried over the years that actually has a noticeable effect. I have two bottles of the capped version that I am looking forward to trying as well; hoping they are as effective as the TD.
Major props to OL for creating such a fantastic product. Please don't ever change it!!
