The Bundle Math
Individual reagents run $25.00 a bottle. The bundles exist because almost nobody should own exactly one reagent, cross-verification is what makes reagent testing trustworthy. Here is the raw math before the nuance:
| Bundle | Price | Reagents | Cost per reagent | vs buying separately |
|---|---|---|---|---|
| Essential 3-in-1 | $60.00 | 3 | $20.00 | saves ~$15 |
| Pro 6-in-1 | $108.00 | 6 | $18.00 | saves ~$42 |
| Elite 10-in-1 | $150.00 | 10 | $15.00 | saves ~$100 |
The savings scale hard, but so does the chance you own bottles you never open. The right buy depends on what you actually test.
Essential 3-in-1, $60.00: Best for Most People
The 3-in-1 picks its three reagents to maximize class coverage rather than depth: Marquis (stimulants, MDxx, opioids), Morris (ketamine and dissociatives), Ehrlich (LSD and indoles). One box answers the first-pass question for the three most common drug families.
Pro 6-in-1, $108.00: Best Coverage per Dollar
The 6-in-1 is where reagent testing stops being single-data-point and starts being a fingerprint. Six reagents means every major substance gets checked by at least two independent chemistries, the standard harm reduction services actually operate at.
Elite 10-in-1, $150.00: Best for Community Testers
The Elite bundle is every major reagent in one case, the specialist bottles included (Robadope for primary amines, Folin for piperazines) are exactly the ones that matter when someone hands you a mystery pill at 1 AM.
Our Recommendation Tree
- You test occasionally, various substances → 3-in-1
- You specifically use MDMA → MDMA Complete Kit instead (see why)
- You test monthly or for friends → 6-in-1
- You are the person your community brings samples to → Elite 10-in-1
- Any of the above → add fentanyl strips; no bundle includes immunoassay strips
Whichever tier you land on, store the bottles cool and dark, and put a porcelain tray ($12.50) in the cart, reading colors against white ceramic instead of a kitchen plate is the cheapest accuracy upgrade that exists.
Frequently Asked Questions
Do the bundles cost less than buying bottles separately?
Yes, and the discount scales: roughly $15 saved on the 3-in-1, $42 on the 6-in-1, and $100 on the 10-in-1 versus $25.00-per-bottle individual pricing.
Will I use all ten reagents before they expire?
Honest answer: solo users usually will not, reagents last 1-2 years and the specialist bottles see rare use. The 10-in-1 makes economic sense for community/volume testers; the 6-in-1 is the ceiling for most individuals.
Why do bundles not include fentanyl strips?
Strips are immunoassay technology (antibody-based), not colorimetric reagents, and are consumed one per test. They are sold separately at $5.50 per 10-pack and belong in every setup regardless of bundle tier.
Which bundle is best for MDMA specifically?
None of them, the dedicated MDMA Complete Kit ($25.00) with Marquis + Simon's + Froehde is the tighter buy for pure MDMA use. The bundles win when you test across multiple substance classes.
