Trimix dosing question

[depdog1]

Hoping I can get a lil help here. I was prescribed Trimix: PAP30/PHE1/PGE25, (I only inject .03Ml) so I believe the strength is plenty strong for me. My question is I’m wanting to go to a cheaper pharmacy that is also local. The local pharmacy offers 4 choices for Trimix 30-2-50, 20-2-30, 10-1-30 and a 5-.05-15. Can someone tell me what’s the closest formula to what I’m receiving now? I hope I didn’t make this too confusing.
Thanks!
