Why MODTECH
exists
My dad's health was going the wrong way, and I started looking into anything that might help. That search led us to a peptide therapy clinic, the kind where everything is done under a doctor's supervision. That clinic is where I first saw a pen like the ones we sell.
When I went looking for one myself, the options were rough. Anonymous listings, blurry photos, no guidance, and nobody to email when something didn't make sense. For hardware this precise, that didn't sit right.
So I decided to see if I could do it better myself. I wanted to provide what I couldn't find: clear photos, a manual that stays current, and straight answers when you have a question. What started as a way to help my dad turned into MODTECH Supply.
Every MODTECH cartridge is steam sterilized and individually sealed in a CE/ISO 11607 certified pouch — the same packaging standard used for medical instruments — and every pouch carries a steam indicator you can see before you open it. The pens are machined from solid aluminum with a 60-click dial at 0.01 mL per step: a fixed click you feel, not a graduation mark you squint at.
What you can
count on
-
01
Sealed one at a time
Every cartridge is steam sterilized and arrives individually sealed in a certified sterilization pouch with a steam indicator. An intact seal means sterile. If a pouch is torn or open, set that cartridge aside.
-
02
Precision hardware
Machined aluminum body, 60 click stops, 0.01 mL per click. The same dial position gives the same amount on your fiftieth session as on your first.

03
Fast, tracked delivery
Orders ship from Amazon's U.S. fulfillment centers — typically 3 to 5 business days, or 1 to 2 with Buy with Prime. Tracking is emailed automatically, and the packaging is a plain Amazon box.

04
A 7-day guarantee
If something isn't right, we replace it or refund it in full. A damaged pen is a replacement conversation, not a repair project. Read the full guarantee.

05
A manual that stays current
No printed instructions ship with orders. The Help Center is the manual, so the answers you find are never an outdated leaflet in a drawer.
