7Seas vs Dozo 7OH: Which Dual-Line House Fits Your Routine?

7Seas and Dozo both refuse to be single-lane 7-OH brands. 7Seas splits its catalog between a 125 mg per-tablet 7-OH line and a Full Spectrum kratom tablet line at 200 mg per tablet, covering both the concentrate buyer and the whole-leaf loyalist. Dozo runs its Perks family across three lanes: standard 7-OH at 50 mg per tablet, Extreme Potency at 100 mg, plus Pseudo and MG-X side lines. The core difference: 7Seas diversifies across alkaloid categories; Dozo diversifies across strength and alkaloid variants inside one tablet family.

7Seas (7-OH + Full Spectrum • 125–200 mg per tablet) vs Dozo (Perks family • 7-OH, Pseudo, MG-X lines)

Quick verdict

Buy 7Seas if you want a heavy 125 mg 7-OH tablet at a standout $0.062/mg single-bottle price, with a Full Spectrum kratom line in the same catalog for lower-intensity days. Buy Dozo if you want one tablet family with a 50 mg standard rung, a 100 mg Extreme rung, and Pseudo and MG-X variants, all in consistent 4-count bottles with Box of 5 bulk options.

• 7Seas: Pick for heavy 7-OH value plus whole-leaf option
• Dozo: Pick for variant depth inside one family

Deep Dive

Potency and formulation deep dive

7Seas concentrates its 7-OH firepower in one SKU: the 500 mg / 4 ct at $30.99, a 125 mg per-tablet dose at $0.062/mg that undercuts most heavy tablets on 7oh.com. The Box of 10 at $205 pushes that to $0.041/mg. The Full Spectrum line works differently, whole-leaf style kratom tablets at 800 mg / 4 ct ($19.99) and a 200 mg single ($4.99), where the milligrams measure total material rather than isolated 7-OH, so the two lines are not directly comparable on per-mg math.

Dozo's Perks family covers more ground in smaller steps. Standard Perks 7-OH runs 200 mg / 4 ct ($34.99, 50 mg per tablet, $0.17/mg). Extreme Potency doubles the tablet to 100 mg at 400 mg / 4 ct ($49.99, $0.125/mg). The Pseudo 400 mg / 4 ct ($37.99) swaps in pseudoindoxyl chemistry, and MG-X 500 mg / 4 ct ($29.99) is the value outlier at $0.06/mg. Box of 5 bulk options cover the 7-OH, Extreme, and Pseudo lines at $135 to $200.

Range

Product range and SKU depth

7Seas runs two clearly separated lines, 7-OH concentrate and Full Spectrum kratom, each with a bulk Box of 10. The catalog is short but spans two product categories.

Dozo keeps everything under the Perks banner: four variants, uniform 4-count bottles, and three Box of 5 options. Buyers never leave the family, they just change lanes.

Quality

Quality, transparency, and lab testing

Both brands ship through 7oh.com's standard batch QC covering 7-OH assay, heavy metals (Pb, Cd, Hg, As), and microbial contamination. 7Seas' Full Spectrum line adds a consideration: whole-leaf material carries different contaminant risk than isolate tablets, so batch microbial screening matters more there. For Dozo, the question is consistency across four parallel formulations. Neither publishes third-party COAs prominently, and neither has had a publicly reported recall.
