Where The Value Is
Larger vials always price better per mg. Tirzepatide 60mg works out to $6.00/mg vs $9.00/mg for the 15mg. Retatrutide 30mg lands at $9.90/mg vs $12.00/mg for the 15mg. If you've already decided which compound you want, go for the biggest vial your storage setup can handle.
What Ships With A Fat Loss Order
Every lyophilized vial ships sealed under nitrogen with its original lot certificate-of-analysis (CoA) and a tracked courier label. Bacteriostatic water is a separate add-on under Reconstitution Solutions — most first-time buyers drop a 30 mL bottle into the same cart.
Buying & shipping FAQ
What you need to know before ordering fat loss vials.
How fast does shipping take on fat loss vials?
Tracked courier, 3–5 business days to most US addresses. Every incretin vial above the 12 mg size qualifies for free shipping on its own (free at $200+).
Do I need bacteriostatic water with a GLP vial?
Yes — every Retatrutide, Tirzepatide, Semaglutide, Cagrilintide vial ships as dry lyophilized powder and needs reconstitution. Add a 30 mL bottle of BAC water to your cart on your first order. Capsules and pre-dissolved liquids (BAM-15, L-Carnitine, SLU-PP-332 30 mL) do not need it.
How do I store the vial after it arrives?
Sealed lyophilized vials are stable at room temperature in transit. On arrival, refrigerate (2–8 °C) if you're using within weeks, or freeze at −20 °C for long-term storage (24+ months).
Can I return an opened vial?
No — opened or reconstituted vials cannot be returned for stability reasons. Unopened sealed vials in original packaging are typically eligible for return within 14 days of delivery.
How is payment handled?
Clicking Buy sends you to our partner supplier's secure checkout with our referral code already applied. We don't see or store card details.
