Customer Reviews
10 reviewsGREEN is such a good colour choice — looks incredible
Ordered the GREEN because I wanted something different and it absolutely delivers. The anodised finish is rich and vivid. But beyond looks the pen is exceptional — auto-injection is smooth, dose dial is precise, and I barely feel the needle. Running BPC-157 and compliance is now perfect.
Best injection pen I have used at this price
Solid aluminium build, consistent auto-injection, and the GREEN anodise is a head-turner. I compared this to two other brands and the Dunyu V1 wins on build quality and dose consistency. Day one use with the included needles — no waiting.
Eliminated injection hesitation completely
I had genuine anxiety about self-injection. The Dunyu V1 push-button mechanism fires confidently and I barely register it happening. The GREEN is a gorgeous colour and makes the pen easy to spot in my bag. Couldn't be more satisfied.
Great pen — love the GREEN
Very happy with this purchase. The mechanism is smooth and the GREEN finish is striking. Dose dial is easy to read and locks in reliably. Would love a protective carry case included, but overall this is excellent value and a joy to use daily.
Made my daily protocol effortless
Before this pen I was dreading injections. Now it takes 30 seconds and I barely think about it. The GREEN Dunyu V1 is beautiful and the auto-inject is flawless. Comes with needles too so I was up and running immediately.
Zero wasted solution — every dose counts
Switched from syringes and the efficiency gain is real. No dead space, no wasted peptide. The GREEN finish is vibrant and distinctive. Running Retatrutide and the dose precision has noticeably improved my results. This pen pays for itself quickly.
My peptide partner in green
Love everything about this pen. The GREEN is my favourite colour so it was an easy choice. Six months in and the mechanism is still as smooth as day one. Protocol compliance is now perfect and I'd never go back to syringes.
Excellent daily peptide pen
Reliable mechanism, clean anodised GREEN finish, and the dose dial is intuitive. Arrived with needles ready to go. Would rate 5 stars if it came with a carry case. Otherwise exactly what you'd want from a professional injection pen.
The click is so satisfying and consistent
Every dose is delivered with the same confident click. I love that I can hear and feel exactly when it fires. The GREEN Dunyu V1 is a joy to use daily. Three months in with zero issues.
Travel-friendly and reliable
Took this pen through three interstate flights and it performed perfectly every time. The GREEN finish makes it easy to identify in any bag. Compact, reliable, and the auto-injection is consistently smooth. Would buy again without hesitation.
