⚠ Contaminated BAC water from Amazon seller — November 2025

From the other side of the consultation, briefly.

Comparison of compounded dosing arithmetic delivery formats I've tried:

I use lyophilized vials for cost and stability. The reconstitution takes 30 seconds once you've done it a few times.

Bacteriostatic water quality matters for dosing arithmetic reconstitution. Not all BAC water is created equal:

• Should contain 0.9% benzyl alcohol as preservative
• Must be sterile and pyrogen-free
• Should come in a sealed, intact vial
• Check expiration date — yes, BAC water expires
• Store at room temperature, protected from light

I buy from a reputable medical supply company, not Amazon marketplace sellers. The $3 savings isn't worth the infection risk from unverified BAC water.

Ongoing cost tracking for dosing arithmetic — transparency for the community:

Monthly medication cost: $130
Supplies (syringes, BAC water, alcohol swabs): ~$8/month
Janoshik testing: ~$10/month (amortized quarterly)
Lab work: ~$40/month (amortized quarterly)
Total: ~$190/month

Compare to brand Wegovy at $1220/month without insurance. Compounded is roughly 88% cheaper for what I have found to be clinically equivalent medication.

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

What did you change at the same time, and can you separate the two now?
