## Questions & Answers

**Q: Is this kratom? If not is it similar**
A: Not kratom, not similar. Not good.

**Q: If your product contains no Kratom, then why is your product listed first under Kratom?**
A: Kratom isn't available on Amazon anymore, so when you search for it, you pull up products with desired results that are comparable. BOO FDA!!!

**Q: All this is is valerian root? You can get that at Walmart for $6-$8 bucks. Good grief.**
A: This is a combination of three ingredients: Valerian, Passiflora, and Magnesium Carbonate. The reasons this costs what it does versus the supplements at Walmart are three-fold: 1. The process used by Dee Cee Labs makes these ingredients more bioavailable; 2. Passiflora (passion flower) is more difficult to find; and 3. The ingredients are in higher concentration than those you'll find at Walmart. Both the Valerian and Passiflora are at Quad Strength in the Formula 303.

**Q: How do I return this for the guarantee? It makes me jittery and angry and gives me a headache**
A: You can first contact the seller to see if they’ll take care of you directly. This seller has a good record of taking care of the customer but if for some reason they won’t then you simply hit return/replace on the order details for the purchase in your order history.

There’s a very small return window on most vitamins though with all retailers because they have to be destroyed once they’re opened if returned by law so if you’re past that window unfortunately Amazon may not be able to help either.

### ⭐⭐⭐⭐⭐ All natural relaxant
*by A***R on January 29, 2026*

Good quality pain reliever/relaxant. My acupuncturist told me about this product years ago. It’s all natural and effective.

### ⭐⭐⭐⭐⭐ Muscle spasm relief
*by N***A on January 20, 2026*

This product really works for muscle spasms in my back. I recommended it to my daughter and she says it’s effective too. It’s nice to have relief. It was originally recommended by a chiropractor in Colorado. It arrived just as predicted.

### ⭐⭐⭐⭐⭐ Buy this, use as directed and enjoy the relief. The odor is worth it.
*by T***T on October 12, 2022*

For those fishermen and women out there, you will appreciate the description of the smell here... it smells like legit stink bait for catfish. That may be an actual second use for these. Now that we have addressed the smell... I have been fighting muscle tightness from my desk jockey job, working out, yard work, automotive repair, stress, etc. for years. I've been to physical therapy (helped, especially with dry needling) and am enrolled in a special exercise and stretching routine. Nothing has helped as much as these tablets. In my experience, the sciatica, joint and muscle pain would only subside when the muscles finally relaxed and for some reason it seemed impossible for it to be consistent enough to enjoy my lifestyle pain free. This combination of natural substances with this level of quality have been a huge help. It's still only been about a week, but it might not be too soon to call these life changing. I am 6' tall and about 180. I have been taking 2 in the morning and before bed and 2 at each meal. Slightly more than the instructions for spasms, but most recommendations are for 160 lb people. I do not plan on keeping up that regiment, but will cut back a little at a time. The biggest thing is that I can do my stretches and workouts without the added challenge of working around the pain. This seems to be key for those who are like me and really needed that domino to fall to work back the years of damage. I can focus on technique and not pain avoidance (which can cause more issues). On about day two I would describe the results as something like the day after a massage and a day or so after dry needling. It's truly amazing so far. Note that the ingredients also promote a positive mood and stress relief. Good for muscles and a better night sleep.
