Safety & Storage

Lyophilised (powder) — refrigerate or freeze

Unopened vials can be stored at 2–8°C for 6–12 months. For longer storage, freeze at −20°C. Avoid repeated freeze-thaw cycles — they degrade the peptide structure.

Reconstituted (in solution) — always refrigerate

Once reconstituted, store at 2–8°C. Use within 30 days. Never freeze a reconstituted solution — it will denature the peptide.

Protect from light

UV exposure degrades peptides. Keep vials in their box or wrapped in foil. Don't leave them on a bench in natural light.

Check for contamination before each use

Discard if you notice cloudiness, discolouration, or particulate matter. Reconstituted peptides should be clear and colourless.

Always use bacteriostatic water

BAC water contains 0.9% benzyl alcohol, which prevents bacterial growth in reconstituted solutions. Do not use plain sterile water — reconstituted peptides won't remain stable.

Standard reconstitution: 1–2ml BAC water per vial

Adding 1ml gives you a 1mg/ml concentration (for a 1mg vial). Adding 2ml gives 0.5mg/ml. Choose your dilution based on your dosing needs and syringe markings.

Inject BAC water slowly down the vial wall

Do not inject directly onto the powder. Aim the stream at the glass wall, letting it run down. Swirl gently — do not shake. Shaking creates air bubbles and can denature the peptide.

Wait for complete dissolution before drawing

The solution should be completely clear. If any powder remains, swirl gently and wait. Never draw a cloudy solution.

Clean the injection site and vial stopper

Wipe the vial stopper and your injection site with an alcohol swab. Allow to dry before proceeding — wet skin can introduce bacteria.

Pinch and inject at 45°

Pinch a fold of skin at your chosen site. Insert the needle at a 45° angle into the subcutaneous fat layer — not into muscle. For most people, this is 12–16mm deep.

Inject slowly, withdraw cleanly

Push the plunger slowly and steadily. Withdraw at the same angle you entered. Apply gentle pressure with a swab — do not rub.

Rotate injection sites

Injecting repeatedly into the same spot causes lipodystrophy (fat tissue damage). Rotate between left and right abdomen, upper thighs, and outer arms.

Dispose of needles safely

Use a sharps container. Never recap needles by hand. Never put loose needles in household waste. Sharps bins are available from most pharmacies.

Start low, titrate up

Always begin at the lower end of a dosing range and increase gradually. Your optimal dose may be lower than the listed maximum — more is not always better with peptides.

Respect cycle lengths

Most peptides are most effective when used in defined cycles with off periods. Continuous use can lead to receptor desensitisation and diminishing returns.

One new compound at a time

When adding a new peptide to your protocol, introduce it alone for 1–2 weeks before stacking. This lets you identify any individual response or sensitivity before combining.

Track your protocol

Note what you're taking, when, and how you feel. What gets measured gets managed. If something feels off — headaches, unusual fatigue, injection site reactions — stop and seek advice.

Baseline bloods before and after

If you're running a cycle longer than 8 weeks or using GH-stimulating peptides, baseline bloodwork gives you a reference point and flags anything that needs attention.
