Peptides, explained simply.

Just heard about peptides and want to know what they actually are? Start here. Two minutes, plain English, no jargon.

The basics

What is a peptide?

A peptide is a short chain of amino acids, the same building blocks that make up protein. Your body already makes thousands of them and uses them as messengers: one tells you you're full, another tells your skin to make collagen, another tells your body to release growth hormone.

The peptides people use are copies of those messages, or very close to them. Rather than adding something foreign, they prompt your body to do something it already knows how to do.

In practice

How do you actually take them?

Most peptides are a tiny injection just under the skin, with a very fine needle. There are two ways to do it:

Option 1

Vial and syringe

  1. 1

    Your peptide arrives as a freeze-dried powder in a small vial. Mix it with bacteriostatic water (free with your order), or we can mix it for you.

  2. 2

    Draw your dose into an insulin syringe. Our mixing guide shows exactly how many units.

  3. 3

    Inject just under the skin. It's quick, and much easier than people expect.

Option 2

Pen

  1. 1

    We mix your peptide and load it into a pen cartridge for you. Nothing to measure.

  2. 2

    Dial the number of clicks for your dose. The label shows what each number of clicks gives you.

  3. 3

    Press, hold a moment, done. The needle is fine and hidden.

More about the pen

Semax and Selank also come as ready-made nasal sprays: no needle and no mixing.

The Primogen pen

The easiest way to start.

If the mixing and the needles are what's holding you back, the pen takes care of both.

Mixed and loaded for you
We make up your peptide and load it into the cartridge. Mixing is included with the pen.
Dose in clicks, not maths
Every click is exactly 0.01ml, and the label shows what each number of clicks gives you. No syringes to read.
A hidden needle
Fine and out of sight, so it feels far less daunting than a syringe.
Built to last
Steel casing, made to the ISO 11608 pen standard and rated for thousands of doses. When a cartridge runs out, swap in the next.

The honest answers

Is it legal? Is it safe?

Legal in Bali

Peptides are not controlled substances in Indonesia. We're stocked here in Bali and deliver locally, so there's no customs gamble.

Peptides and the law in Indonesia

Safe, used properly

Anything that works deserves respect. The evidence varies by compound: a few are approved medicines, many are earlier-stage research. We tell you what's known and what isn't, start you on a sensible dose, and answer your questions before and after you order. Adults only. If you're pregnant, have a medical condition or take medication, check with your doctor first.

We can fill pens and cartridges for you too.

Yes, free with every order. We include a 3ml allowance of bacteriostatic water per vial you buy, made up from a mix of our 3ml and 10ml vials so it covers your whole order. Use as much or as little per vial as your protocol needs. Extra is available if you want it.
