Performance. Recovery. Strength.
New Zealand owned and operated. Every batch independently lab-tested and shipped as a complete reusable pen kit, with a Certificate of Analysis you can verify.



We don't hide where our peptides come from.
We import from the world's most trusted lab-tested manufacturers, and every batch is independently verified by Novagen Laboratories. Verify every certificate yourself, below.
Don't trust us. Trust the lab.
Every certificate carries a unique verification key from Novagen Analytical Labs, an independent third-party analytical laboratory. Look any report up on Novagen's own site and confirm it yourself. We can't fake what an independent lab publishes, so we don't try to.
We sell the full kit, not just the vial.
Most sellers hand you a vial and wish you luck. Every Synergy Bio order arrives as a complete, ready-to-assemble kit in a thermal hard case.
A proper pen. A tiny needle. No guesswork.
Other sellers ship you a bare vial and a fistful of big syringes. We give you a complete kit with a refillable dosing pen and a tiny needle head, so taking your peptides is simple, precise and barely-there. Here's the difference.
You're not jabbing yourself with a big syringe. A Synergy Bio pen needle is tiny and short, most people barely feel it go in.
No drawing up and measuring every day. Dial the clicks on your pen and you're done in seconds, the exact same dose, every time.
Assembled in four simple steps.
Your kit comes with everything pictured above. Here's the order it goes together.
Reconstitute
Draw bacteriostatic water with the syringe and add it slowly to the peptide vial. Swirl gently, never shake.
Draw your dose
Use the extraction syringe to measure your starting dose accurately from the reconstituted vial.
Load the pen
Transfer into the aluminium pen and twist on a fresh needle head ready for a clean, precise dose.
Dose & store
Dial your dose on the pen, then return the vial to the case and refrigerate at 2-8°C between uses.
Never done this before? We'll show you.
Short, clear videos that walk you through mixing and loading your pen, then dial your dose in clicks with the tool below. No experience needed.
Reconstituting your peptides
How to mix bacteriostatic water into your vial, the right way.
Filling your peptide pen
Loading your reconstituted peptide into the pen, ready to dose.
Turn your dose into clicks, instantly.
No maths, no guesswork at the pen. Drag the slider, choose your dose, and see exactly how many clicks to dial, for both Retatrutide and GLOW.
- Live clicks calculator, your dose straight to pen clicks
- Retatrutide and GLOW ratios, set to your 2 mL reconstitution
- Quick reference tables and clear safety notes

Chat on WhatsAppPeptides, explained honestly.
There's a lot of noise out there. Here's the plain version of what peptides actually are, and what they're not.
"Peptides are some exotic, high-risk drug, basically a steroid." That's the myth that keeps people either scared off or careless.
Peptides are short chains of amino acids, the same building blocks your body uses to make every protein. Many, like GHK-Cu, are produced naturally in your body already.
They're amino acids
Signalling molecules, not foreign chemicals. Your body recognises and uses them through existing pathways.
Investigational compounds
Published research to date describes a favourable tolerability profile at the doses studied. These compounds remain investigational and are supplied for research use only.
Naturally declining
GHK-Cu levels in the body fall significantly with age, part of why it's so widely studied for skin and repair.
Our honest note: for research that runs longer than six months, periodic analytical testing is the responsible way to track a protocol over time.
Learn the science, peptide by peptide.
In-depth, honest research guides to every peptide we supply. No hype, no medical claims, just clear science, the research, and verifiable third-party testing.

Questions, answered plainly.
Are peptides safe?
Peptides are short chains of amino acids, the same building blocks the body uses to make proteins, and several, like GHK-Cu, occur naturally in the body. Published research to date describes a favourable tolerability profile at the doses studied, but these compounds remain investigational and are supplied for research use only. For any questions about your own health, speak with a qualified healthcare professional.
What does 'research use only' mean?
It means these products are supplied for laboratory and educational research. We're transparent about this because it's the truth, and because being honest about it is part of doing this properly.
Do I need blood tests?
Where a research programme runs beyond six months, ongoing monitoring of relevant biomarkers is standard good practice in the literature. We cannot give personal health advice; anyone considering their own use should consult a qualified healthcare professional.
Where do you source from?
We don't hide it: we import our peptides from the most trusted, lab-tested manufacturers around the world. Every batch is third-party tested with a verifiable Certificate of Analysis from Novagen Analytical Labs, an independent third-party analytical laboratory, which you can request and read.
How do I put my kit together?
Every kit includes a reusable pen, bacteriostatic water, your peptide vial, five needle heads, an extraction syringe and a thermal case. Reconstitute, draw your dose, load the pen, then dose and store. The four-step guide and assembly videos on the site walk you through it.
How do I order?
There's no online cart. You simply message us on WhatsApp, tell us which kit you'd like, and we walk you through everything, including the COA and how payment works. It's quick, personal and there's no obligation.
How much do the kits cost?
Pricing depends on the kit and the current batch, so we confirm it directly when you message us. It's quick, there's no obligation, and we send the batch Certificate of Analysis at the same time.
How fast is shipping?
We dispatch quickly from Auckland with tracked express. Most New Zealand centres often arrive next business day, most capital cities in 1 to 3 business days, and regional areas in 2 to 5. We ship right across New Zealand.
How is my order packed?
Every order is packed with no branding on the outside, and sent in an insulated thermal case so it travels well in any climate.
I'm new to peptides, can you help?
Absolutely. That's the whole point of the kit and our guidance. Message us with any question and we'll walk you through reconstitution, the pen, and our interactive dosing guide, so nothing is guesswork.
