Currently running FD2 and Or1gin. Just started bottle #2 of FD2 and I'm about 2 weeks into Or1gin.
Seeing usual effects from Epicatechin products for my body (fullness, pump and very high stamina, some strength increase but mainly stamina) these are typical for my body and epi, but I'd say FD2 is producing above average results, in comparison to other epi products I have run which have all been satisfactory for me.
It is worth noting that I'm eating in a 300-400 kcal surplus. My diet has not been the "cleanest" in the last month and a half or so but it could certainly be worse. I have gained both muscle and some fat which was to be expected as I have also cut out cardio. I work a physical job on the railroad, in the winter it slows down a bit and hours are cut back into a fairly "normal" range, 45-50 hours a week or so as we are just maintaining the track so there is a lot of driving around, working for 20 minutes to an hour and getting back in the truck to drive to the next spot. In the spring/summer/fall we are working on large projects with tight deadlines and 12-16 hour days are usual and the work is nonstop. With that being said I'm not burning as many calories at the moment as compared to the rest of the year where it is very hard for me to cleanly eat even at maintenance (convenience plays a large factor in this as well)
So those are some of the big variables to take into account.
Disclaimer: I have not taken Or1gin solo.
From my short experience with Or1gin so far, I find it is easier to eat and I don't feel as full when I eat, which is very helpful. I've been sleeping quite well, but it has also been a priority of mine to be getting more rest as I believe that has been one of the week points in my program. I feel as though my strength has been increasing more than usual in the last few weeks with usual weight feeling lighter, doing more reps resulting in me upping the weight. Which also a product of increase in macros and rest but I feel as though the Or1gin is playing a role in this as well.
So far I am very happy with both products. It is also worth noting I'm not taking Tr1umph at the moment, which is usually a staple of mine but after the black Friday sales I got some good deals on PES Select and Ergonine so I thought I'd give Tr1umph a break to try the Ergonine. I'm very happy with the Ergonine as an all in one staple but will be returning to Tr1umph for the addition of PA.
Throughout the time mentioned here I have been using a modified P.H.A.T. lifting program. Typically lifting 6 days a week on a revolving cycle of push/pull/legs. I have been using this for quite a while as it is flexible for me in regards to how I'm feeling that particular day and I can incorporate a varity of different lifts in while adjusting the intensity. For example if I have a very long and intense day at work spiking or swing a sledge Hammer all day, it's probably not the best idea to go for super heavy sets as my body is already fatigued and I may be risking injury or just disappointment if you get what I'm saying.
In the end you can say what I'm experiencing is simply a reflection of my diet, rest, and current work "schedule".
I honestly believe both products are working, not at the level of real gear or a PH (I dont think anyway as I've never run either) but I'm happy. If you want to say it's a result of the variables listed/talked about, then by all means go for it. As I said before these are just my experiences and my opinions based on me and my body
