Look, I'm not gonna sugarcoat this. If you're reading about rad-150 stacks, you've probably already decided you're doing this. Maybe your buddy at the gym won't shut up about his gains, or maybe you hit a wall that regular training just can't break through anymore.
Whatever brought you here—I get it. Been there myself. Spent way too many nights down Reddit rabbit holes trying to figure out what actually works versus what's just bro science garbage.
So let's talk stacking. But like, actually talk. No corporate wellness blog nonsense.
Except my training partner was stacking his cycle and the dude absolutely exploded. Same timeframe, way better results. That got me researching—okay fine, obsessively researching—what combinations actually moved the needle.
Here's what I learned works. And what doesn't.
First stack I tried. RAD-150 at about 15mg daily, MK-677 around 20mg before bed.
Why before bed? Dude, MK-677 makes you HUNGRY. Like, standing in front of the fridge at 2am hungry. Taking it at night means you sleep through the worst of it, plus it helps with recovery while you're out.
The pumps though... man. Sometimes I'd have to stop mid-workout because my forearms or calves would cramp from being so engorged. Annoying? Kinda. But also means it's working.
Gained about 12 pounds over ten weeks. Not all muscle, obviously—MK-677 makes you hold some water. Probably 8-9 pounds was actual tissue though, which ain't bad at all.
One weird thing nobody warned me about: vivid dreams. Like, REALLY vivid. Not nightmares exactly, just... intense. Apparently that's common with MK-677. Goes away after a few weeks.
This stack's interesting because you're chasing two different things that normally don't play nice together—losing fat while keeping (or even building) muscle.
Ran this last spring getting ready for a vacation. 12mg RAD-150, 15mg Cardarine. Split the Cardarine dose—half morning, half pre-workout.
Cardio became... easier? That's the only way to describe it. My usual 5K time dropped by almost 90 seconds without even trying harder. Just had more gas in the tank.
The fat loss was gradual, nothing dramatic weekly. But over eight weeks? Yeah, I could see abs that had been hiding for a while. And my lifts barely budged down, some even went up slightly.
Fair warning—Cardarine got some sketchy cancer study results in mice. Were they giving the mice absurd doses? Yes. Does it still worry some people? Also yes. Do your own research on that one.
Haven't personally run this yet, but my gym partner did. So this is secondhand, take it for what it's worth.
He was stuck on a 315 bench forever. Like, six months of grinding and barely moving the needle. Ran RAD-150 with YK-11 for eight weeks—hit 335 by week six, 340 by week eight.
The tradeoff? Felt like hammered shit during PCT. More suppressed than other stacks, took longer to bounce back. He said it was worth it for breaking through, but wouldn't run it back-to-back with anything else.
YK-11's mechanism is different—it messes with myostatin, which basically tells your body when to stop building muscle. Blocking that? Recipe for growth. But also recipe for needing solid recovery after.
Get yourself:
You absolutely need the best post cycle therapy you can manage after running rad-150. Not optional. Not "maybe." Definitely.
I learned this the hard way on my first cycle ever (different compound, same lesson). Thought I'd be fine, tried to cheap out on PCT. Week three post-cycle I felt depressed, tired all the time, zero interest in... anything, if you catch my drift.
Proper PCT brought me back, but those three weeks sucked. Hard.
Standard protocol's something like Nolvadex for 4-6 weeks after your last dose. Some guys add Clomid, some throw in natural test boosters. At minimum, get the SERM. Everything else is negotiable, that's not.
Also? This stuff amplifies effort, doesn't replace it. Seen plenty of guys take compounds then train like garbage and wonder why nothing happened. The drugs open the door—you still gotta walk through it.
Your diet needs to be dialed. Sleep matters more than you think. All that basic stuff your coach probably told you? Still applies, just more important now.
Get bloodwork done. Plan your PCT before you start. Buy all your support stuff upfront, don't wait.
And maybe don't tell everyone at the gym what you're doing. Some people get weird about it.
That's pretty much it. Not complicated, just requires being smart about it and not cutting corners.
Whatever you decide—stay safe out there.

Why I Even Started Looking Into Stacks
About a year back, I ran rad-150 solo for eight weeks. Decent results, nothing crazy. Added maybe 7-8 pounds, strength went up on most lifts. Cool, right?Except my training partner was stacking his cycle and the dude absolutely exploded. Same timeframe, way better results. That got me researching—okay fine, obsessively researching—what combinations actually moved the needle.
Here's what I learned works. And what doesn't.
The "I Want Size" Combo

When You're Trying to Cut But Keep Muscle

The "Screw Plateaus" Approach
Mixing RAD-150 and YK-11Haven't personally run this yet, but my gym partner did. So this is secondhand, take it for what it's worth.

Stuff You Actually Need (The Unglamorous Part)
Nobody wants to talk about support supplements. Boring. Not sexy. But you know what else isn't sexy? Jacked up liver enzymes and feeling like trash.Get yourself:
- Something for liver support—I use NAC, cheap and works fine
- CoQ10 for heart stuff
- Fish oil (yeah, basic, but your lipids will shift on cycle)
About That PCT Thing Everyone Ignores

What Nobody Tells You
Starting conservative beats starting aggressive every single time. You can always do more next cycle—hell, you'll probably want to. But you can't unfuck yourself if you go too hard too fast.Also?

Where I Landed On All This
Different stacks for different goals, obviously. Bulking? RAD-150 and MK-677 crushes it. Cutting? Cardarine's your friend. Need to break a plateau? YK-11 might be the answer, just respect the recovery time after.Get bloodwork done. Plan your PCT before you start. Buy all your support stuff upfront, don't wait.
And maybe don't tell everyone at the gym what you're doing. Some people get weird about it.
