Strength increase is both not as much and not as rapid. However tissue accrual and hardness are superior. With those two methyls, the size is seriously all water, couldn’t gain any new ground. Sarms don’t cause that water gain but do actually increase tissue. Once they are fully “kicked in” after about 4 weeks, the CNS fires pretty hard, mind and muscle connection is strong. After about 48 hours from stopping usage the hardness is gone, strength is down somewhat, m/m connection is not as strong.
I think they’re as androgenic in the skeletal muscle tissue as a steroid. They’re selective, remember, so they could be ten times more androgenic than tren but you’d never know because they physically cannot bind to any tissue which would evidence such a thing.
I am now fully confident in the power of sarms, and as an alternative to a test-only cycle or the test stacked with whatever cycle, stacking LGD/osta at 24+/44+ will absolutely give similar effects/results and can be run a similar length of time. So you can stack em with test, or without, depending on what you want.
But they don’t kick in for a few weeks, so an oral steroid to kickstart would still be appropriate. They’re also not going to fully shut you down, which is where most of the sides come from. It’s displacing the testosterone still available and making it more effective as a result. That’s why they also always seem to say they stop working if you get too suppressed or fully shut down.
We don’t have enough data to know fully how they work to build muscle, just that they do for sure.
Also, I wouldn’t be too worried about tainted sarms. If they’re tainted it’s just either nothing, or ATD and nolva in there, you won’t notice any effects, no gains, no nothing. So far as can be shown by the only study done on the subject, nobody has put anything but other sarms or atd/nolva into sarms.
