4-Pro-MET doses range from about 2 mg (microdose) to 25+ mg (high dose), based on community research reports. None of this is clinically validated. All figures come from anecdotal reports and structural analogy to 4-HO-MET, which Alexander Shulgin documented at 10-20 mg oral in TiHKAL (1997). What follows is a community-sourced breakdown of dosage tiers, expected effects at each level, and the safety details that actually matter.

This table summarizes community-reported dosage tiers for oral 4-Pro-MET. These are estimates from harm-reduction communities and vendor sources — not clinical data.

A microdose means sub-perceptual to barely perceptual — typically 1/10th to 1/20th of a standard dose. For 4-Pro-MET, that's roughly 2-5 mg based on community protocols. At this level, no visual or cognitive distortions appear. What researchers do report: subtle shifts in mood, focus, and creative thinking that may last several hours.

The two most popular schedules are the Fadiman protocol (dose every third day) and Stamets stacking (4 days on, 3 days off). Precision matters a lot here. Even within the microdose range, 3 mg can feel noticeably different from 5 mg — serotonergic psychedelics have steep dose-response curves, and that steepness doesn't flatten out at the bottom.

This is where most community researchers land. The 10-15 mg range aligns with Shulgin's documented 10-20 mg for 4-HO-MET in TiHKAL, adjusted for the ~20% mass correction. Reports at this level consistently mention geometric patterns, enhanced colors, euphoria, and that characteristically clear headspace that sets MET-series compounds apart from more introspective DMT-series tryptamines.

But the dose-response curve within this window is steep. Really steep. Community reports describe the gap between 10 mg and 15 mg as substantial — the former offers a manageable, recreational-level experience, while the latter pushes toward significantly more immersive territory. This is typical of serotonergic psychedelics and exactly why precise measurement equipment isn't optional.

Since 4-Pro-MET is a prodrug of 4-HO-MET, cross-compound dose equivalence comes up constantly. The ~20% mass correction means milligram-for-milligram, 4-Pro-MET is less potent than 4-HO-MET.

These comparisons are approximate. Individual sensitivity, set and setting, and compound purity all shift the actual experience. And cross-tolerance between all these compounds kicks in within a 7-14 day window — they share the same 5-HT2A receptor mechanisms.

With milligram-active compounds, accurate dosing isn't a suggestion. It's a requirement. The equipment you need depends on the form:

• Pellets: No equipment needed if using the manufacturer's stated dose. For splitting, use a pill cutter (expect reduced precision).
• Powder: An analytical balance with 0.001g (1 mg) readability is mandatory. Models cost approximately 20-50 EUR and are widely available.
• Liquid drops: Use a calibrated 1 mL graduated syringe for best accuracy (+/- 2%). Standard droppers may vary by 10-20% between drops.
• Volumetric dosing: Dissolve a known quantity in a measured volume of solvent, then measure the desired volume. This gives the highest precision for any form and is the recommended method for microdosing protocols.
