I constantly felt like I had a golf ball of mucus stuck in my throat that I could never fully clear. After using this for about two weeks I'm finally coughing up all that junk and my throat feels normal again.

What Customers Have to Say...
Linda R,
Honestly I bought this thing half expecting it to be another waste of money. But around week two I started coughing up all this dark stuff and my husband thought something was wrong. Third week I took a full shower standing up the whole time. Haven't done that in three years.

I quit smoking three months ago, but my lungs still felt disgusting and full of tar. This spray helped me cough up so much black stuff I didn't even know was in there. My breathing is clearer now than it's been in years. rate it a 15/10.

I know I should quit, but I'm not there yet, so in the meantime, I wanted something to help clean out my lungs. This actually helps me breathe better even though I'm still smoking, and I'm coughing up less gunk in the mornings.

Simple tasks like getting dressed used to leave me breathless, and it was honestly depressing. This spray has helped reduce that suffocating tightness just enough that I can move around my house without feeling like I'm going to pass out.

How The QuadStim Formula Works
Just 2 sprays a day loosens stuck mucus buildup, calms airway irritation, and supports easier breathing. Unlike single-ingredient options that only thin mucus, this multi-action formula targets the root cause so your airways can finally stay clear.
Eucalyptus
Eucalyptus helps loosen thick, stuck mucus so it’s easier to clear from the chest. As mucus breaks up, breathing often feels more open and less heavy. Users typically describe a clearer, fresher airway feeling after use.
Peppermint
Peppermint helps cool and soothe irritated airways that feel tight or scratchy from congestion. That cooling effect makes each breath feel more comfortable and less strained. It’s especially valued when breathing feels hot, dry, or irritated from coughing.
Licorice Root
Licorice root helps calm airway irritation signals that can drive ongoing mucus production. When irritation settles down, mucus tends to feel less constant and less aggressive. This supports steadier, more comfortable breathing instead of repeated mucus flare-ups.
Calendula
Calendula helps soothe raw throat and airway lining stressed by repeated coughing. When tissues feel less irritated, breathing and swallowing feel more comfortable. Users often value this for post-cough recovery comfort.
What to Expect
WEEK 1: EARLY SIGNS
Mucus starts loosening and coming up more easily. You probably won't notice a major difference yet, but it's already working.
WEEKS 2–3: IT'S SPITTING TIME
This is when you'll start coughing up thick dark mucus. Don't panic, that's the old stuck layer finally breaking apart. The deeper it clears, the easier every breath gets.
MONTH 1: BREATH FREELY
That stuck feeling in your throat starts to fade. Showering, sleeping, spending time with family, all without stopping to catch your breath. For the first time in a long time, you feel like yourself again.
What 2,200+ Supporters Have to Say...
I honestly didn't think anything could help after years of smoking and not taking care of myself. I was skeptical, but I gave this a shot. When I took a deep breath to test it out, there was no wheeze or whistle, just air. Thank you alot.
I've dealt with constant mucus in my chest for years, and I was always clearing my throat or feeling that clogged feeling. Within a few days of using this I started coughing up lots of mucus. Now my chest actually feels lighter.
I've had COPD for five years, and while I'm still on my regular meds, this spray has helped take the edge off that tight suffocating feeling in my chest.
I started waking up choking on phlegm in the middle of the night and it honestly scared me into trying this. Now I'm finally sleeping through the night without gasping for air.
