Doubt they are valuable as much with both Manly Man and Muscle Roar. In theory you will get better results from adding as much recovery as possible to spam Muscle Roar without diminishing returns. Lots of stuff possible here, below list isn’t complete.
So some free addons are Muscle Recovery 2.0, Platelet Rich Plasma^2 Bath, HGH or The Bone Strengthener, Creatine Synthesis, Induced Follistatin to Muscle, Fa Jin Gong Infusion from The Flow.
20E Pepper and The Quick and Easy Muscle Cheat (Fa Jin Gong infusion into muscle with general recovery) from paid fields.
Of course to put more energy and building blocks into cells free Enhanced Cellular Nutrient Absorption and paid maybe Endocriner?
Everything that improves mitochondria efficiency, most would recommend free SuperHuman Mutant or its paid SuperHuman Mutant RNA upgrade.
Now each SARM audio can have potential advantage on its own barring androgen receptor activation, as it’s of dubious added effect with two ones you already use. Ostarine should in theory have marked effect on recovery, tendons, positive and stabilizing effect on mood. Rest are less useful. LGDs are mostly for androgenicity which is not needed in larger amount and YK-11 will not add better myostatin inhibition with Muscle Roar.
Cardarine and Stenabolic usually are discussed together with SARMs. Both can help you with energy metabolism and recovery if used consistently, so probably useful. Shift towards slow muscle fibers is probably not a concern with Muscle Roar pushing hypertrophy directly.
Longer answer 
and all speculation on my side. So hope that maybe others can chime in on the topic of fields there and if they actually can give added value. Also hearing how people use Muscle Roar would be nice, schedule and number of times specifically.
), so here’s my experience:
(not that I would’ve been able to afford them.)
