They’ve been running it in a metabolic study for about 8 weeks now, and the 10mg vials are what most buyers go with for dosing flexibility—the lyophilized powder reconstitutes cleanly in water or DMSO, though I’d avoid the latter unless you’re prepping for a specific solubility test. 2. It’s not ideal for anything beyond research, obviously, and we usually have stock on the 8mg and 15mg sizes, but the 30mg vial is a tighter call on lead time (check availability first). 3. The HPLC and mass spec data on the COA is solid, and the ≥99% purity holds up batch to batch, which is better than reagent grade for this type of work. 4. Storage at -20°C is non-negotiable, and one thing you don’t think to ask is that teh powder can clump slightly if exposed to humidity during reconstitution—just let it warm to room temp before opening. 5. Anyway, the GMP cerification is in place, and they’ve been sourcing form a facility with ISO 9001 for a couple years now, so the consistency is there. 6. 3-5 business days on orders under 50 vials, give or take, and the 12mg size is actually most popular for, but I’d confirm the MOQ if you’re mixing sizes.

We don't enforce a strict MOQ, so you can order as little as a single vial in most cases. For bulk orders over 100 vials, we offer discounted pricing—just reach out for a quote.
For stock items like Retatrutide, we ship within 24 to 48 hours after payment confirmation. International delivery usually takes 5-12 business days depending on your location.
Yes, each batch comes with a certificate of analysis (COA) that includes HPLC and mass spectrometry results. We can share the latest report before you place an order.
Keep it at -20°C in a freezer, away from light and moisture. The lyophilized form stays stable for months under those conditions—just don't freeze-thaw repeatedly after reconstitution.
Each vial is individually sealed and labeled with the exact amount, so there's no cross-contamination. You can absolutely mix different sizes in the same order—just specify in the notes or let our team know.
