4-Pro-MET Bundle

Buy 4-Pro-MET Bundle at 4promet

Drops, micro pellets, macro pellets – all in one order. Saves money and you’ll have the right dosage form for every experiment at hand. Every product in the 4-Pro-MET bundle is individually HPLC-tested at 99%+ purity. Three products, three certificates – all available online. When you buy a 4-Pro-MET bundle, you get the full range of dosing options in one package at 4promet.

All Dosage Forms in One Set

Why place three separate orders when you can get everything together? The 4-Pro-MET set covers the entire research spectrum: drops for continuously adjustable dosing from 1 mg, microdosing pellets with standardized 2 mg and macrodosing pellets at 20 mg for higher dose ranges. From sub-perceptual microdosing protocols to standard doses – one order, everything included.

Price Advantage Over Individual Purchase

The math is simple: all three products cost more individually. The 4-Pro-MET value pack offers a genuine price advantage – plus you save on shipping since everything arrives in one delivery. For labs systematically working with different dosage forms, this is the most economical option.

Why Order the Bundle at 4promet?

We exclusively make tryptamines – and we do it right. When you order the 4-Pro-MET bundle: HPLC-tested 99%+ purity for each individual product, complete batch tracking, discreet EU shipping within 48 hours, free shipping from €50. Three products, three certificates of analysis, one package. Straightforward.

What Does the 4-Pro-MET Bundle Contain?

Three products that complement each other. Each component is separately HPLC-tested and comes with its own certificate of analysis. All products are exclusively intended for research purposes – not for human consumption. Here’s what the 4-Pro-MET complete set contains:

4-Pro-MET Drops (1 mg per drop)

The liquid variant for maximum flexibility. Dissolved in pharmaceutical-grade propylene glycol (Ph. Eur.), filled into amber glass with a calibrated dropper insert. One drop = exactly 1 mg 4-Pro-MET. No scale needed. Particularly practical for microdosing protocols and pharmacokinetic time series where you need to fine-tune the dose.

Microdosing Pellets (2 mg per pellet)

One pellet, one dose – sub-perceptual research doesn’t get simpler. Each pellet contains exactly 2 mg 4-Pro-MET in a stable, easy-to-handle form. The advantage over drops: longer shelf life and no risk of mis-dosing. Ideal for long-term studies and reproducible experimental protocols.

Macrodosing Pellets (20 mg per pellet)

When more is needed: 20 mg 4-Pro-MET per pellet for standard doses. Designed for receptor binding studies, pharmacological investigations and experiments requiring higher substance amounts. The pressed form lasts over 12 months – maximum stability, minimum storage effort.

Quality Assurance and Laboratory Analysis

Three products in the set, three separate tests. No collective report, no generalizations. Every product in the 4-Pro-MET bundle undergoes its own HPLC analysis, receives an individual certificate and a unique batch number. Only batches with at least 99% purity are released.

HPLC Analysis for Each Product

HPLC (High Performance Liquid Chromatography) – the gold standard in pharmaceutical quality control. Each of the three products is tested separately: is the active substance content correct? Are there impurities? The certificates document purity, identity and batch number – all available online. Triple-tested, triple-transparent.

Complete Batch Tracking

Each product bears its own batch number. That sounds like a detail – but it’s essential for reproducible research. You can precisely document which batch of which product was used in your studies. The triple batch tracking is actually a genuine unique feature compared to individual purchase: you have the information there too, but with the bundle you have it for all three forms from one order.

Applications of the 4-Pro-MET Bundle in Research

The real strength of the bundle? You can directly compare different dosage forms – under identical conditions, from the same source. The research chemical bundle covers the entire dosing spectrum and opens up experimental possibilities that wouldn’t be available with individual products.

Comparative Studies

How does the dosage form affect 4-Pro-MET stability? Does the active substance dissolve faster from drops than from pressed pellets? And how does the rate of hydrolysis behave? Such questions can only be answered when all forms come from the same source – same purity, same synthesis route. That’s exactly what the bundle delivers.

Method Validation

Liquid in propylene glycol, pressed with binder – each matrix presents different analytical challenges. Labs use the bundle to validate their HPLC, GC-MS or LC-MS/MS methods across different matrices. Does the method work as reliably for drops as for pellets? With the set, you’ll find out.

Research Lab Equipment

Just getting into tryptamine research? Then the bundle is your starter kit. Instead of evaluating individually and reordering step by step, one order gives you everything you need. Saves time, shipping costs and the administrative overhead of three separate orders.

Order 4-Pro-MET Bundle – Easy and Discreet

Straightforward and without detours. Select the bundle, add to cart, done. When you order the 4-Pro-MET complete set: no hidden costs, no lengthy registration form. Just order and know it’s on its way.

Fast Ordering Process
