I'm gonna say something I bet no one has yet:
All three of your "schools of thought"... Are true.
SARMS are incredible. They provide great gains and minimal sides, compared to other non-hormonal OTC products.
SARMS are trash. Or at least potentially, because we don't know the long term effects, which might easily outweigh the benefits of them. Their gains are minimal compared to all that is available for muscle growth and in some cases, their sides are just as bad or possibly worse.
SARMS are a good addition to any PH/AAS cycle. Well yes, this one is true if you are interested in creating an edge to your cycle that would otherwise not exist. I routinely hear that Ostarine is fabulous with Test.
Like we said in times past - if you value legality over all else or you have a phobia to needles then SARMs are always worth more to you than someone who doesn't mind using traditional AAS.
Nuff said.
