Retlira Pen — What It Is, and Why We Supply Retatrutide as Vials
“Retlira” searches are almost always about the pen format. We do not sell pens, so here is what the name means and what we offer instead.
WHAT WE DO NOT SUPPLY
We do not sell Retlira, any pen, or any UPA product, and we are not affiliated with UPA. We supply retatrutide as research vials only — for laboratory research use, not for human or veterinary use, and not registered with SAHPRA.
Retlira 30 is the name UPA uses for a retatrutide pre-filled pen, listed by local resellers as 30 mg in 3 ml. A pre-filled pen holds the compound already in solution.
We supply retatrutide only as a lyophilised (freeze-dried) powder in a sealed vial, in 30 mg and 60 mg, with a free 3 ml BAC water per vial for laboratory reconstitution. Lyophilised powder is the form research compounds are normally shipped in, because it is far more stable in transit than a solution.
Our retatrutide is independently tested by Janoshik Analytical: 99.676% HPLC purity (task #197337, on a 40 mg sample), verifiable with the lab by QR. We cannot speak to any other label’s product.
We hold stock in Johannesburg and dispatch nationwide with The Courier Guy. Orders confirmed before 12:00 SAST on a business day are typically dispatched the same day, otherwise the next business day; Gauteng is usually next business day and the rest of the country one to two business days, door-to-door with tracking.

Questions
Do you sell the Retlira pen?
No. Retlira is a UPA product, and we do not sell pens at all. We supply retatrutide as lyophilised research vials in 30 mg and 60 mg.
Why vials and not pens?
Freeze-dried powder in a sealed vial is the standard research format: it is more stable in transit and storage than a compound already in solution.
Is your retatrutide the same as Retlira?
Same molecule, different supplier and format. We do not claim it is the same product. Ours carries an independent Janoshik Analytical report.
