Keeping it right.

The vials arrive cold and sealed, as a dry powder. Unmixed, they go into the fridge on the day they arrive, in the door or on a shelf, away from the freezer compartment. Dry, they keep for months. The water arrives with them and lives in the same place. Nothing on the sheet needs to be mixed until the day it starts, and the vials for week five and week nine should stay unmixed until then.

Keep them in the box or a small container so they are not knocked about, and keep them out of the light. A fridge is dark most of the day, which is the point.

Once the water goes in, the clock starts. A mixed vial lives in the fridge and is used within about four to six weeks; the sheet says how many weeks each vial covers at your rhythm, and most are finished well before the limit. Mix by letting the water run down the inside of the glass and leaving it to dissolve; never shake. Swirl gently if you must. Shaking is the single most common way a vial is ruined.

Take the vial out, draw the dose, put it back. Do not leave it on the counter while you do something else, and do not leave it in a bag. The fridge door is fine; the freezer is not. A frozen vial is a finished vial. How many weeks a mixed vial covers at your dose is what the vial duration tool works out, and the strength you mixed is the first thing the calculator and the unit converter ask for.

A weekend in Cebu or a week in Singapore is fine with a small insulated pouch and an ice pack, the kind sold for insulin, which is exactly what it is for. Keep the vial upright and the pouch out of the sun. On arrival, straight into a fridge. For a long weekend, take only the vial you are using; the unmixed ones stay home.

Flying is fine. Insulin syringes and a small vial go through security in most countries without comment; carry the printed protocol, which says what each vial is. Keep it in cabin baggage, never in the hold, because the hold freezes. The supplies checklist counts vials and syringes for the days away from your plan.

Heat, above all. A vial left in a car in Manila, in a bag on a beach, or on a windowsill is finished, and it will not look different. Light, over time. Shaking, which breaks the peptide chains that the water was meant to dissolve gently. Freezing. And time itself, past the weeks on the sheet. None of these announce themselves; the vial looks the same and simply does less, which is why the rules are firm.

Use the sheet's timeline. A vial that has been mixed longer than the sheet allows, or that has spent an afternoon warm, is replaced. That is a cost, and it is the reason the protocol starts you with one vial and not everything.

Monday, the box arrives cold. It goes into the fridge unopened, and the one vial the sheet starts you with comes out that evening or the next morning. You mix it once, at the counter, by letting the water run down the glass and leaving it for a few minutes, and it goes back into the fridge door. From then on the rhythm is the same: out, draw, in, back. Thirty seconds. The syringes live in a drawer and the used ones in the lidded container. Nothing sits out, nothing travels in a bag, and the vials for week five and week nine stay unopened at the back until their week comes.

The only day that needs thought is a travel day, and the pouch and ice pack cover it. Everything else is a habit inside a week, and the habit is the point: a vial handled the same way every day, in the same place, at the same temperature, is a vial that does its work to the last dose, and a fridge door is where that happens.

Everything ships cold and sealed, and once it has left the cold chain it cannot come back into it, so all orders are final. That is not a policy written to avoid refunds; it is what cold-chain means. It is also exactly why the protocol tells you what to buy first and what to leave until week five, and why the first order is one compound and the water. Buy the core. Nothing else yet.

Which is why this page exists. Handle it right and every vial does what it was bought for. The first-protocol guide covers the first week and the injection guide the first injection. Take it to a doctor who knows you before you begin.
