What this calculator does

A weekly dose can be taken as one big injection or spread across several smaller ones. Spreading it out keeps levels steadier and, for some peptides, is just easier on the injection site. This calculator does the division: pick a compound, enter the weekly dose, choose how often you inject, and it returns the amount for a single injection.

Schedule can be set as times per week, like twice or three times, or as every so many days, like every third day. Every-X-days schedules can land on a fractional number of injections per week, which is normal and shown as an approximate figure. Add the vial concentration, and for GLP-1 powders the water you mixed in, to also get the units to draw.

Reading the result

The main number is the dose per injection in the compound's own unit. The injections-per-week figure confirms how the schedule was read, and the syringe-units line appears once there is enough information to compute a draw. Testosterone esters use the concentration directly as milligrams per milliliter; reconstituted GLP-1 vials need the water volume to work out their strength first.

Common questions

How do you split a weekly dose into smaller injections?
Divide the weekly total by the number of shots. A 2 mg weekly semaglutide dose split twice a week is 1 mg per shot, and split every other day, which is about 3.5 times a week, it is roughly 0.57 mg each. The weekly amount stays the same, you are just spreading it out.
Is splitting a GLP-1 dose better than one weekly shot?
Some people split semaglutide or tirzepatide to smooth out the peak and hope for fewer side effects like nausea. The evidence is mostly anecdotal, and these drugs have long half-lives that already even things out. It is a personal experiment, not a proven upgrade, so talk to your provider before changing a prescribed schedule.
Does splitting a dose reduce side effects?
For some people, smaller and more frequent doses feel gentler because the blood level swings less. Others notice no difference at all. It varies a lot by person and by drug, so the honest answer is it might help you or it might do nothing.
How do I split a weekly TRT dose?
Take your weekly testosterone amount and divide by how often you inject. 100 mg a week becomes 50 mg twice a week, or about 28.5 mg every other day. Splitting TRT is popular because shorter esters like testosterone cypionate cause less of a peak-and-crash between shots.
What is the difference between twice-weekly and every-other-day dosing?
Twice a week means two shots, usually spaced 3 to 4 days apart. Every other day means about 3.5 shots a week, so each one is smaller and levels stay steadier. More frequent shots mean more needle sticks but less swing between doses.
