Has anyone bought for example a single 100 mg reta vial, and then made their own 10 mg kit out of it? It appears vials and milligram scales are available on Amazon for not much money. Though the “value add” step would seem to make sure you’re maintaining sterility.
I would strongly advise against this. There are several major problems with that idea.
First these vials always contain peptide plus excipients/filler, so it's going to be 100mg of Tirz plus an unknown amount of filler. Without validated lab data, you have no way of knowing how much of that powder is actually tirz and how much is filler. So weighing out “10 mg portions” doesn’t mean you’re getting 10 mg of tirzepatide. You’d just be weighing 10 mg of mixed powder.
Second, consumer milligram scales are not reliable enough for that level of precision. Static, humidity, airflow, and transfer loss all affect powder measurements. You could easily end up with inconsistent amounts.
Third, and most importantly, sterility. Redistributing peptide powder into new vials requires sterile pharmaceutical handling. Labs do this in controlled environments with laminar flow hoods and validated sterile technique. Doing this at home introduces contamination risk you can’t see.
So you’d be dealing with three major unknowns:
You don’t know the true peptide content
You can’t reliably portion it accurately
You can’t realistically maintain sterility
If you’re even considering this, it would be wise to spend more time reading about peptide formulation, excipients, and sterile handling first. Injectables are not a place to learn through a bright idea or trial and error.
