H1: 2C-B-FLY 20 mg Pellets | The Cleanest, Most Precisely Dosed “Fly” Compound Available in 2025
RC King’s 2C-B-FLY 20 mg pellets are the current gold standard: pressed in-house under cleanroom conditions using triple-recrystallized 2C-B-FLY dihydrochloride (latest batch 99.93–99.98%) and minimal pharma-grade binders. Every single pellet is quantified by UHPLC-MS to exactly 20.0 mg (±0.3 mg) — the most accurate and consistent 2C-B-FLY dosage form ever offered commercially.
For scientific, forensic, and serotonergic receptor research only. Not for human consumption.
Product Description
Small, white, round, scored pellets (6 mm). Professional hard press, no dyes, no unnecessary fillers. The preferred format for researchers studying the unique 5-HT2A/22C profile of the dihydrodifuran “Fly” series.
What is 2C-B-FLY?
2C-B-FLY (8-bromo-2,3,6,7-benzo-1,4-dioxepino[5,4-c]ethylamine) is a conformationally restricted analog of 2C-B in which the 4-position is bridged by a dihydrodifuran ring system. First synthesized by Aaron P. Monte in 1996 and popularized in the mid-2000s, it is widely regarded as one of the most visual, musical, and emotionally warm phenethylamines still researchable worldwide.
- IUPAC: 2-(8-Bromo-2,3,6,7-tetrahydrofuro[2,3-f][1]benzofuran-4-yl)ethanamine
- Strength per pellet: exactly 20.0 mg active (±0.3 mg)
