Compounded tirzepatide or Phentermine (generic): which publishes a price?
Only one of these two publishes a verified all-in price, which settles the comparison before any other axis is reached: Compounded tirzepatide at $125–$278, and no figure at all for the other. Phentermine (generic) is the better choice of the two, winning on regulatory and complaint risk and brand vs compounded (halfrx score 3.1 against 2.9). Every axis below is computed from stored fields rather than written by hand, so the comparison moves when a price does. Flags recorded here: Compounded tirzepatide — not fda approved, manufacturer lawsuit, supply risk. One is compounded and the other generic, which is the difference between an FDA-approved product and a copy made under the compounding exemption. The published formula scores them 2.9 and 3.1 out of 10, arithmetic over the same stored fields rather than an editor's preference.

Read the price gap carefully: these two are not the same purchase
- These are different molecules — Compounded tirzepatide on tirzepatide, Phentermine (generic) on phentermine — so this is a comparison of two treatments, not of two prices for one.
Compounded tirzepatide
Pros
Cons
- −Not FDA approved — no review of safety, efficacy or manufacturing quality.[1]
- −Eli Lilly has active lawsuits against compounded tirzepatide sellers, including Henry Meds. A ruling against your provider ends your supply.[2]
- −The tirzepatide shortage that legally permitted mass compounding has been resolved, so the category now operates on contested legal ground.[2]
- −Zepbound vials through LillyDirect start at $299/mo — the branded gap is far smaller than it was, which weakens the only argument for compounding.[1]
Phentermine (generic)
Pros
- +The cheapest drug in the category by two orders of magnitude: $0.068 a tablet at pharmacy acquisition cost against $263 for one Zepbound pen.[2]
- +Covered by more Medicaid programmes than any GLP-1 — seven states cover an older weight-loss agent while covering no GLP-1 at all.[3]
- +One tablet each morning, no injection, no titration schedule beyond a possible half dose.[1]
Cons
- −Approved for a few weeks only. Every monthly subscription selling it as ongoing therapy is using it off the label's own duration.[1]
- −Schedule IV controlled substance, chemically related to the amphetamines, with the dependence warnings that follow from that.[1]
- −Stopping after prolonged high dosing brings extreme fatigue and depression, per the label — which is a hard exit from a subscription that sold it as maintenance.[1]
- −No cardiovascular outcome data of the kind the GLP-1s now carry, and contraindicated where blood pressure is uncontrolled.[1]
