How do I choose the size of the vials to order?

Starting with the smaller size makes sense, then stepping up to bigger containers once you know how fast you're moving. I did the reverse, grabbed the larger ones for the supposed savings, and ended up discarding material because they lasted longer than expected. At week eleven I'm still struggling with anything over 3 mg, so the climb could be slower than planned. You won't know your pace until you actually try it. For the leftover amount that doesn't divide evenly, just finish the partial vial and pull the rest of that week's dose from a fresh one.

I agree with the suggestion to begin with a kit of smaller vials and move to larger ones as needed. At the same time, quite a few people here keep a mixed vial past the usual 28-day mark without obvious issues. It comes down to how much risk you're comfortable accepting versus how much product you're willing to discard.

Opinions vary, but here's mine. Larger concentrations clearly cost less per unit. One workable approach is to mix several smaller bottles together into a single stronger solution. For instance, after mixing one small bottle you can pour that liquid into a second small bottle to double the concentration in the same volume. If your dose rises faster than expected, you can combine what you have. On the other hand, if a bottle lasts many weeks at a low weekly amount, most people simply keep using it for up to eight weeks. I would map out a tentative schedule but adjust it based on how your body actually feels once you begin.

Not advice, just observations from someone else. A coworker began at half a milligram to reduce possible side effects and never needed more than 2 mg across six months. That was simply how he reacted. It might be worth letting your own response set the pace instead of a fixed timeline. For the visceral fat specifically, another compound has shown promise in studies and carries approval for that use; it could be worth exploring as an addition if that remains a priority.

The earlier comments are solid, but I want to stress that no one can forecast their reaction ahead of time. A given weekly amount might feel mild or quite strong; the only way to find out is to start. Plan to adjust as you go rather than locking into a preset plan.

Begin at 2 mg using a 10 mg vial mixed with 1 ml of diluent; that setup gives about ten weeks of shots. You'll move to 4 mg after four weeks and start using the material faster. Before long the kit will be gone and you'll be looking at the next size up. Around here a single 10 mg vial now counts as one dose.

There's a related thread running at the same time that asks why anyone would choose anything above the smallest common vial size when making a first purchase.

Same point everyone else is making: the smaller vials will cover four to eight weeks. The earlier replies cover it well.

Solid points throughout the thread. My first container came already mixed and I moved straight to 2 mg, then to 4 mg after about six weeks. I kept using it until empty. The usual guidance is 28 days after mixing, though many here go longer. Clean technique matters more the longer you push it, and the quality of the diluent makes a difference too.

An online tool exists that calculates how to finish one vial at one dose level and begin the next vial at a different level without losing accuracy. It has been very useful for planning transitions between concentrations.

Two main factors to balance are how long one vial lasts after mixing and how often you have to mix new ones. Keeping the number of mixing sessions low is convenient, but doing extra mixes is always an option. Some people even enjoy the process. A chart comparing dose levels to expected months of use for different vial sizes might help visualize the trade-offs.

It's good you're thinking through a plan ahead of time. As others noted, actual response can't be known until you start; you might move slowly or quickly, hit side effects, or find it isn't suitable. Regardless of prior research, your experience will be personal. Looking at totals: a kit of ten 10 mg vials holds 100 mg overall. Starting at 0.5, 1, or 2 mg and following a typical four-week escalation produces roughly four months of supply before you need more, but you control the actual pace.

Thanks to everyone for the quick replies. I work in a technical area and usually stick closely to published protocols and trial data. The suggestion to watch how my body handles 2 mg instead feels more practical. If that amount produces steady loss of a few kilograms per month, that would meet my goal exactly.
