Appreciate the work that goes into this. For anyone budget-conscious — I've been tracking price per mg across all Tier 1 and Tier 2 sources: | Source | Price | Amount | $/mg | |--------|-------|--------|------| | CompoundPharm Direct | $159 | 5mg | $31.80 | | PeptideSciencesRx | $129 | 5mg | $25.80 | | TeleMedCompound | $299/mo | ~10mg/mo | $29.90 | | ResearchChem Outlet | $79 | 5mg | $15.80 | | GLP1Direct | $139 | 5mg | $27.80 | ResearchChem is cheapest per mg, but you're trading off domestic shipping speed and the grey-cap batch hasn't been tested yet. PeptideSciencesRx offers the best value domestically if you're comfortable reconstituting yourself. Caveat: cheaper isn't always better. I'd pay the premium for consistent COAs and reliable shipping any day.

As a healthcare professional lurking here — I want to emphasize something that gets lost in the price comparisons. The compounding pharmacy's license, their sterility protocols, and their beyond-use dating (BUD) are critically important. A 503B facility is required to do sterility testing on each batch. A 503A pharmacy may or may not, depending on state regulations. If you're injecting something subcutaneously, sterility is non-negotiable. Ask your source: what is the BUD on the vial? If they say more than 30 days for an aqueous solution without a preservative like benzyl alcohol, that's a red flag. Properly preserved multi-dose vials typically get a 60-90 day BUD. Also, check if they use 0.9% benzyl alcohol as preservative — that's standard. Some cheaper sources skip it, which means once you puncture the vial, you're on a very short clock before bacterial contamination becomes a concern.
