From the other side of the consultation, briefly.

Sharing my dosing arithmetic titration experience with compounded semaglutide — I have been tracking injection volumes meticulously:

Using 5mg/2mL concentration with 1cc insulin syringes:

  • Month 1: 10 units (0.25mg) — mild appetite reduction
  • Month 2: 20 units (0.5mg) — significant appetite suppression
  • Month 3: 30 units (0.75mg) — custom intermediate dose
  • Month 4: 40 units (1.0mg) — optimal for me, staying here

The beauty of compounded vials is you can do custom intermediate doses. My provider was great about tailoring to my response.

Ongoing cost tracking for dosing arithmetic — transparency for the community: Monthly medication cost: $124 Supplies (syringes, BAC water, alcohol…

For anyone reconstituting dosing arithmetic peptides: the water-to-powder ratio determines your concentration. Here's my reference:

Vial SizeBAC WaterConcentration0.25mg Dose
5mg2mL2.5mg/mL10 units
5mg2.5mL2mg/mL12.5 units
10mg2mL5mg/mL5 units
10mg3mL3.33mg/mL7.5 units

More water = easier to measure small doses but vial runs out faster. Find the balance that works for your dose.

Following on from TrialTracker_MD — and this may be the naive question:

What a vetting checklist should actually contain, as opposed to a list of things that are easy to fake?

Peptide calculator app recommendation for dosing arithmetic: I use DoseRight to calculate reconstitution volumes and injection doses. Eliminates math errors completely.

Input: vial size (mg), desired concentration (mg/mL), prescribed dose (mg)
Output: BAC water volume (mL), injection volume (units on insulin syringe)

A math error with injectable medication can mean underdosing or overdosing. Use a calculator every time until the math becomes second nature.
