Start here — your vial is powder
It is freeze-dried. You add the bacteriostatic water yourself, once, and then it is ready for every dose in that vial. Do this before anything below.
Wipe the rubber top of both vials with an alcohol swab and let them air dry.
Work out how much water to add — the calculator below tells you, per vial size.
Draw that much bacteriostatic water, then push the needle into the peptide vial and let the water run down the inside of the glass, not straight onto the powder.
Swirl gently. Never shake. Shaking damages peptides. Give it a minute — it should go completely clear.
Store it in the fridge, out of the light. Put it back in the box it arrived in, or a light-blocking case — either one keeps the light off it. Use a fresh needle for every dose.
Your needle is already on. He screws his onto the luer lock in the video — yours arrives assembled, so skip that part.
He uses a 30 mL bottle of bacteriostatic water. Yours is likely a 3 mL or 10 mL bottle. Same process, smaller bottle — the amount you draw is whatever the calculator below tells you, not his.
If your vial says it is pre-mixed, or the product is a capsule or a skin serum, none of this applies — the calculator will tell you.

Now the injection itself
Subcutaneous — into the fat just under the skin, not into muscle.
Swab the spot (belly a couple of inches from the navel, outer thigh, or back of the arm) and let it dry.
Draw your dose, point the needle up, tap the barrel and push out any air bubble.
Pinch a fold of skin. Insert at 45–90° — with a short insulin needle, straight in is fine.
Press the plunger slowly, count to five, then withdraw. Light pressure after; do not rub.
Rotate sites so you are not using the same spot twice in a row.
Used needles go in a sharps container — never loose in household rubbish.
If you feel faint, short of breath, or the site swells badly, stop and get medical help. Research use only — this is not medical advice.

For ready-to-draw oil-based injectables (e.g., testosterone esters) — already in solution, no mixing. Just enter the strength printed on your vial.

Vial concentration (mg/mL)

This is printed on your vial label. US pharmacy testosterone is usually 200 mg/mL; compounded is often 250. Double-check it — 200 vs 250 changes your dose by 25%.

Syringe type
i
On a U-100 insulin syringe, 1 mL = 100 units. Read the barrel — U-40 syringes ship in our boxes.
A 0.5 mL or “50 unit” syringe is still a U-100 barrel — it is a smaller barrel, not a different scale. Pick U-100 for it. Only pick U-40 if the barrel itself counts to 40.

Educational tool — not medical advice. Testosterone is a prescription medication. Your prescriber and your bloodwork set and adjust your dose — this calculator only converts a dose you already have into syringe units. It does not recommend a dose. Standard practice is to start low and titrate by labs (total/free testosterone, estradiol, hematocrit, PSA) drawn at trough. Always work with a qualified provider and follow applicable laws.
