R20-3P — SPB Retatrutide
Vendor COASPB | Retatrutide, last activity 1 month ago
SPB rarely publishes certificates, making this batch distinctive on that count. The vendor's Janoshik certificate reports endotoxin at 1.003 EU/vial, within the 10 EU/vial limit; a Freedom Diagnostics Testing certificate was also published but without reported figures. No independent test has been submitted. First seen within the last month.

Test Results
Dosing with this lot
The label says 20 mg. Freedom Diagnostics Testing weighed 20.1 mg. Your dose depends on what is really in the vial, so the calculator uses the measured amount.
Draw
20 units
on a U-100 insulin syringe, for 2 mg
- The vial holds dry powder: 20.1 mg of Retatrutide, as weighed.
- Water spreads that powder evenly through the liquid: 20.1 mg ÷ 2 ml = 10.1 mg per ml.
- An insulin syringe counts in units, 100 to the ml, so each unit carries 101 mcg.
- Your dose divided by that: 2 mg ÷ 101 mcg = 20 units.
The water changes how many units a dose takes, never how much peptide you get. Twice the water means twice the units for the same dose. What sets the dose is how much is in the vial — which is why the measured amount matters.
Arithmetic, not medical advice. Assumes a U-100 syringe and that the powder fully dissolves. The figure is from the vial that was tested; yours is from the same lot but was not weighed itself.
