Customers Questions Answered
We get a lot of similar questions from new customers about what they receive, how the pens work, and why we use a reusable pen system instead of disposable pens.
Below you will find clear answers to the most common questions, so you know exactly what to expect when you order.
“What exactly do I get when I place an order?”
When you order from Thrive Genics you receive a complete setup, not just a single disposable pen.
- A high‑quality reusable pen that you can use again and again for your research purposes only.
- Your chosen cartridge(s), each clearly labelled with the compound and strength.
- Cold‑storage handling, cartridges are shipped from chilled storage to protect quality.
- An ice pack and a protective plastic cartridge case for each cartridge.
- Foil‑wrapped outer protection to keep everything secure and temperature‑stable in transit.
- Clear labelling so you always know exactly what you are using.
ACTUAL PHOTOS of the pen and how the cartridge refill arrives
If you order just the pen, you receive the reusable pen, needles and swabs in this protective case.
If you order any cartridge, it arrives like this, sealed with an ice pack inside a foil‑lined bubble pouch.
“How does the pen actually work?”
The pen uses a simple dial system so you can choose a precise, repeatable dose every time.
Step‑by‑step use
- Take the pen and cartridge out of the packaging.
- Insert the cartridge into the pen as instructed (twist or click into place).
- Turn the dial on the pen to select the number of units you need.
- Use the pen to deliver the dose, but please note, NOT for human consumption, then store it back in a cool place.
How dosing works
- Each product page explains how many “units” on the dial equal a specific mg dose.
- Once you know your dose, you simply dial the same number of units each time.
- This gives you consistent, repeatable dosing with no guessing or eyeballing.
“Why do you use reusable pens instead of disposable pens?”
Value and cost
- You buy the pen once and then only replace the cartridges.
- Over time, this works out cheaper than constantly buying full disposable pens.
- More of what you pay goes into the compound itself, not into single‑use hardware.
Waste and control
- Reusable pens create far less plastic waste than throwaway pens.
- You can swap cartridges on the same pen instead of juggling multiple devices.
- The dial gives you more control over your dose than most “one‑setting” disposables.
“Are your pens better quality than disposables?”
Yes. Our latest pens are built to feel and perform MUCH better than typical disposable pens, so using them day‑to‑day is smoother and more reassuring.
-
The internal drive has been refined for a smoother, cleaner turn of the dial, so the plunger is easy to push rather than stiff or jerky.
-
The body is made from solid anodised aluminium with precision‑cut components, giving a stable, premium feel instead of the “cheap plastic” feel of many disposables.
-
The clip‑on lid makes it easy to carry and store your pen safely in a case or pocket.
In short, you are using a proper piece of hardware designed for repeated use, not a flimsy throwaway device.
“Do I need more than one pen?”
Most customers are absolutely fine with one pen. You can attach a cartridge, store it correctly, and then swap to a different cartridge on the same pen whenever you need.
If you prefer to keep different compounds on separate pens for convenience, you can order additional pens, but it is not a requirement for the system to work.
“How long will the pen last me?”
The pen is designed for repeated, long‑term use under normal handling. As long as you look after it and avoid damaging it, you should only need to replace it if it becomes worn or physically damaged.
“How should I store the cartridges?”
Cartridges are shipped from cold storage and should be kept chilled as per the guidance you receive with your order. Keep them away from heat and direct sunlight, and always store them sealed and protected when they are not in the pen.
“Is this system complicated to set up?”
No. If you can twist a cap on a bottle and turn a dial, you can use this system. Most customers are completely comfortable after their first setup and quickly prefer it to disposable pens.
