Why 31 Gauge?

spa

Virtually Painless

At just 0.26mm diameter, 31G is the thinnest commonly available insulin needle. Most users report feeling nothing at all — making it the top choice for anyone anxious about needles.

Perfect for GLP-1

Semaglutide and tirzepatide are thin, low-volume solutions (0.25–1ml). They flow easily through 31G, so you get maximum comfort without any trade-off in injection speed.

Precision Micro-Dosing

The 0.3ml micro-dose variant is designed for GH (growth hormone), small peptide doses, and precise titration. Every 0.01ml marking is clearly visible for accuracy.

Frequently Asked Questions

Is 31G too thin for semaglutide?expand_more
Not at all. Semaglutide is a thin, water-based solution that flows easily through 31G needles. The slightly slower flow is barely noticeable for the small volumes used (typically 0.25–0.5ml). Many Ozempic and Wegovy users prefer 31G specifically because it's virtually painless.
Is 6mm long enough to reach the subcutaneous layer?expand_more
Yes, for most people. The subcutaneous fat layer in common injection sites (abdomen, thigh) starts at about 2-3mm below the skin surface. A 6mm needle comfortably reaches it. For people with very little body fat, pinching the skin before injection ensures proper SubQ delivery.
What's the 0.3ml micro-dose syringe for?expand_more
The 0.3ml syringe has finer graduation marks (0.01ml increments) making it ideal for small, precise doses. It's commonly used for growth hormone (GH), BPC-157, and other peptides where you inject 0.1–0.3ml at a time. The smaller barrel makes it easier to control the plunger for micro-doses.
Should I choose 31G or 30G?expand_more
If comfort is your #1 priority and you inject thin solutions (semaglutide, GH, most peptides), go 31G. If you inject thicker solutions, larger volumes (>1ml), or want maximum versatility, go 30G. Both are great choices. When in doubt, try a 10-pack of each.
Do you ship to my country?expand_more
We ship to all EU countries with free shipping on orders over €50. We also ship to the UK, Switzerland, and Norway with a small surcharge. Orders dispatch within 24 hours and typically arrive in 2–5 business days.
Are these syringes CE-certified?expand_more
Yes. All our syringes are CE-marked Class IIa medical devices manufactured in ISO 13485 certified facilities. They come individually sealed in sterile blister packs. Each batch is tested and traceable.
