Every ingredient in a tablet should be there for a reason you can explain in a sentence. For the corydalis in Tempo, the sentence is: 13-OH corydalis makes a full, standardized 150 mg mitragynine serving feel rounder and smoother, with less sensory harshness. This article unpacks that sentence: what problem it solves, why the ratio is what it is, and how we verify it's in the tablet.
A framing note. We're describing formulation reasoning and how the product feels. We're not claiming corydalis or kratom treats, prevents or cures anything, and the FDA hasn't evaluated any of this.
The problem with kratom alone
Kratom extract at a serving that suits the person is where most people find it most useful: smooth, a little lift, a little calm, sociable. The trouble starts when someone wants "more" and the only lever is more mitragynine. Past a point, extra mitragynine tends to add the things people don't want, such as queasiness, a wired or jittery edge, and a sharper drop at the end, faster than it adds fullness. Experienced users call this the ceiling.
In 2024–2025 the market's answer was to add 7-OH, which is now scheduled above threshold and off the table. The formulation question in 2026 is whether there's a way to get past the ceiling without a higher kratom dose and without a scheduled compound.
What 13-OH corydalis brings
Corydalis yanhusuo is a plant in the poppy family, unrelated to kratom, with a long history of use in its own right. Its rhizome contains a set of isoquinoline alkaloids; the 13-OH-characterized extract Dialed uses is produced by Corydalis Labs and standardized so 13-OH is resolved from tetrahydropalmatine (THP) by HPLC. Background in What Is 13-OH?
In a blend with kratom extract, what we observe and what early customers report is a change in the shape of the experience rather than its raw intensity:
- Fuller at the same mitragynine dose. A 150 mg mitragynine tablet with corydalis reads as more complete than a 150 mg kratom-only tablet.
- Reduced sensory harshness. Less of the edge and queasiness that come with pushing kratom dose.
- Rounder tail. A more gradual finish rather than a cliff.
The practical consequence: the tablet delivers a full, standardized extract serving without needing to push the mitragynine number higher to feel complete, and it stays well under the federal 7-OH line (7-OH is not detected on every lot). That full serving is exactly why the tablet is cross-scored and why we tell everyone to start with half.
The ratio: 150 mg mitragynine to 30 mg corydalis extract
Corydalis Labs recommends 25–40 mg of 13-OH per serving in a blended product. We landed at 30 mg of corydalis extract per tablet against 150 mg of mitragynine (plus 100 mg paraxanthine for clean focus), with the pack label printing the kratom component as a 250 mg kratom alkaloid blend, after working through a few options:
| Option considered | Why we didn't pick it |
|---|---|
| 150 mg mitragynine, no corydalis | A full serving, but noticeably harsher for many; the ceiling problem in miniature |
| 150 mg mitragynine + 15 mg corydalis | Below supplier guidance; the corydalis contribution was inconsistent |
| 150 mg mitragynine + 40 mg corydalis | Top of the range; some testers found it too soft and sedating for a daytime serving |
| 150 mg mitragynine + 30 mg corydalis | Best balance of fullness and clarity across a half and a full tablet; chosen |
The cross-score keeps the ratio intact at a half serving: 75 mg mitragynine, 50 mg paraxanthine and 15 mg corydalis extract. A half is a genuine serving, not a leftover, and it's where everyone should start.
These formula figures are the current published formulation and are confirmed on every lot COA.
What the pairing isn't
- It isn't a 7-OH substitute in the chemical sense. 13-OH is a different molecule from a different plant. Dialed is a 7-OH alternative in the sense of "a compliant product for people who used to buy 7-OH," not because corydalis mimics 7-OH.
- It isn't a potency hack. The goal was a better-shaped serving, not a stronger one.
- It isn't a health product. No medical claims. If you have a medical condition or take medication, consult a physician before using kratom or corydalis.
Testing a two-botanical tablet
Blends are harder to test honestly than single-ingredient products, because you have to assay both actives on the same finished tablet. Dialed's independent lab (FESA Labs, Santa Ana CA, HPLC-DAD) reports, per lot:
- Mitragynine per tablet (target 150 mg)
- 7-hydroxymitragynine per tablet and % dry weight, not detected on every lot (federal threshold 1.00 mg per unit)
- Corydalis extract per tablet, with 13-OH resolved from THP
- Heavy metals, microbials, pesticides, residual solvents
Our COA guide shows what each of those lines looks like. If you see a "corydalis kratom tablet" from any brand whose COA only reports mitragynine, the corydalis claim is unverified.
Sourcing and consistency
A blend is only as consistent as its least consistent ingredient, and botanical extracts vary lot to lot. We source the corydalis component from a single supplier, Corydalis Labs, whose extract is characterized for 13-OH content and shipped with its own certificate. Each incoming lot is checked against the specification before it's blended, and the finished tablet is then assayed again, so the 30 mg figure on the pack is verified twice: once on the raw extract, once on the finished product. The same applies to the kratom extract, which is standardized to mitragynine before blending and re-tested after compression. It's more testing than a single-ingredient tablet needs, and it's the cost of making a two-botanical formula that behaves the same way in March as it does in September.
How it feels in practice
Typical reports from a half tablet: smooth, light lift, clear, social. From a full tablet: fuller, calmer, rounder, with the corydalis more noticeable. Onset is 20–40 minutes; the peak sits around the one-to-two-hour mark; the tail is gradual. Detail in onset and duration. Compared to kratom-only extract tablets, people most often mention the absence of the edge. Compared to 7-OH, they mention that it's slower and doesn't drop off a cliff, which cuts both ways depending on what they wanted. See 13-OH tablets vs 7-OH tablets.

Frequently asked questions
Can I take corydalis and kratom together?
Tempo is formulated and tested as a combined product for adults 21+. As with any botanical, don't combine with alcohol, don't use if pregnant or nursing, and consult a physician if you have a medical condition or take medication.
Why not just use more kratom?
Because more mitragynine tends to add harshness before it adds fullness. Corydalis changes the shape of a full serving instead of pushing the dose up.
Does corydalis make the tablet sedating?
At 30 mg with 150 mg mitragynine, most people describe a full tablet as calm and rounded rather than sedating, and a half tablet as clear and light. Higher corydalis ratios were softer, which is why we didn't pick them.
