What studies say about Modafiendz
We aren’t aware of much peer-reviewed work on it, so treat it as a lightly characterised compound and plan your controls with that in mind.
It isn’t approved anywhere and has no clinical history.
Search PubMed for the full studies. We stick to what’s been published.
Working with Modafiendz in solution
The liquid form saves you the work of dissolving powder. Modafiendz is already in solution at 100mg/mL, so every millilitre holds the same amount. A 1mL draw gives you 100mg.
Use a clean graduated pipette or dropper for each draw so nothing goes back into the bottle. Shake gently first, because some solutions settle over time. We stock transfer pipettes and dropper bottles if you need them.
Making working dilutions of Modafiendz
If your protocol calls for a lower concentration, dilute a measured volume into a clean glass bottle. For example, 1mL of the 100mg/mL solution plus 1mL of carrier gives 2mL at 50mg/mL. Use the same carrier where possible, or a solvent your protocol allows, and mix gently.
Make up only what you’ll use in the short term, and label the new bottle with the concentration and date.
Modafiendz quality and testing
Every batch of Modafiendz is checked with liquid chromatography-mass spectrometry (LC-MS) before it goes on sale. LC-MS separates a sample into its parts and identifies each one by mass, so it confirms what the compound is and how much of the sample it makes up. The current batch tested at 99% or higher.
Small differences between batches are normal, so write the batch number from the label into your records. If something looks wrong when your order arrives, like discoloured powder or a cloudy solution, set it aside and don’t use it.
Storage and handling
Keep it sealed in a cool, dry place away from light. Keep the cap tight so the solution doesn’t evaporate or pick up contaminants. Label anything you decant with the compound, amount and date, and keep it out of reach of children and pets.
