Mixing
Your vial
Add 1 ml of bacteriostatic water to the 10 mg vial. That makes 10.0 mg/ml, so one 2.5 mg dose is 25 units on a U-100 insulin syringe.

Every number here is arithmetic on the dose and frequency in the row above — it is not a recommendation, and nothing about it has been checked against you. Mixing volume is a suggestion that keeps the draw readable on a U-100 syringe; any volume works as long as you redo the maths.

Vial counts round up and assume every vial is used to the last full dose. They ignore waste, priming, and the fact that a reconstituted vial keeps about 28 days in a fridge — the per-compound panel above flags that where it applies. Oral and topical compounds in the cycle are not listed here.

Synergy & safety report

Insufficient data

Add another compound to check for interactions between pairs.

No interactions are flagged between the compounds currently in your cycle. That isn't a clean bill of health — our data only covers pairs someone has documented, and most pairs above have none.

Questions for your prescriber2

Do any of these interact with what I already take, prescribed or over the counter, or with a condition I have?
The site knows nothing about your prescriptions or your history.
What bloods or other checks would you want before I start, and how often while I'm on it?
Nothing here has been checked against your baseline.

This is a prompt for a conversation, not a checklist that clears a cycle. Good answers to all of it still leave the pairs nobody has studied.

This reflects only interactions flagged on each compound's reference page — not a full pharmacological screen. An absent warning means we have no data on that pair, not that it is safe.
