The spreadsheet I built so the reconstitution math stops being guesswork. Enter the vial, enter the water, and it gives you the concentration and the units on the syringe.

3 tabs · Google Sheet · Make your own copy
What's inside
01
Fill in the vial amount, the diluent, and the amount you are working with. It returns concentration, the volume to draw, and the tick mark on a U-100 syringe. No mental arithmetic at 6am.
02
One row per compound: vial, diluent, concentration, frequency, timing, duration, notes. Example rows are filled in so you can see the format, then you overwrite them with your own.
03
How to use it in a minute, and where to find the rest of what I publish. Make a copy first, then it is yours to edit and nobody else sees it.
The most expensive mistake in this whole space is not the vial you bought. It is not knowing what was actually in the syringe.
If the concentration is wrong, everything you conclude afterwards is wrong too. The example rows in the sheet are examples, not recommendations. Nothing in it is a suggestion to use any compound in a human, and the numbers you enter are your responsibility.
Instant access. No cost. Instant access.
The sheet and the guides answer the first questions. The ones after that, is this vendor real, does this COA mean anything, what does the research actually say, are easier to answer with other people in the room. That is what Peptide Talk is.
