Dunyu V1 Peptide Pen - PURPLE

The purple finish is stunning — and it works perfectly

I picked the PURPLE mainly because I loved the colour and I was not disappointed. The finish is rich and even, and the mechanism is absolutely spot-on. Auto-injection is smooth and virtually painless. Zero hesitation every single time. Running my Retatrutide protocol and this has made dosing effortless.

Excellent build quality for the price

Compared to other pens I have used this one punches well above its price point. The aluminium feels solid, the dose dial is precise, and the click mechanism is satisfying and consistent. The PURPLE anodise is vibrant. Happy to have switched from syringes.

No more needle anxiety — this pen changed everything

Needle anxiety was the biggest barrier to my peptide protocol. The auto-inject on this Dunyu V1 fires before my brain can tense up. I barely feel it. The PURPLE looks gorgeous and the dose dial is incredibly easy to read. Couldn't be happier.

Great pen, solid colour choice

Mechanism is reliable and the dose dial locks in exactly where I set it. The PURPLE finish is bold and distinctive. Only minor gripe is I'd love a carrying case included. Otherwise this is a genuinely premium pen at a very fair price.

Day one ready — incredible convenience

Arrived with needles included so I was injecting on the same day it arrived. The PURPLE Dunyu V1 feels premium in the hand and the auto-injection mechanism is flawless. For daily peptide users this is an absolute must-have.

Precision dosing every single time

I was losing probably 10-15% of each dose to dead space with syringes. The Dunyu V1 eliminates this entirely. Dosing is consistent, the PURPLE finish looks slick, and the pen fits comfortably in my travel bag. Highly recommend.

Worth every cent — protocol compliance is now perfect

The barrier to injection is completely gone with this pen. I was inconsistent with my protocol before because of hesitation. Now it's second nature. The PURPLE colour is gorgeous and the build quality is excellent.

Smooth mechanism, beautiful finish

Four months of daily use and not a single issue. The mechanism is as smooth as the day I got it and the PURPLE anodised finish still looks brand new. This pen is clearly built to last. My whole family uses peptide pens now.

Slim, travel-friendly, and reliable

Travel constantly for work and this pen is compact enough to fit in any bag without looking out of place. The PURPLE finish means I can spot it instantly. Mechanism is consistent through flights and temperature changes. Love it.

Great pen — the PURPLE is a statement piece

The colour alone gets compliments. But beyond aesthetics this is a genuinely well-built device. Auto-injection is reliable, the dose dial is smooth and precise, and the included needles are fine gauge and comfortable. Solid purchase.

Switched from GensuPen and love this just as much

Had the GensuPen 2 for a while and decided to try the Dunyu V1 PURPLE. The mechanism feels just as good and the size is very similar. The purple colour is a beautiful change. Zero complaints — this is a top-tier pen at a great price.
