Testosterone Blends
The number on the label is combined ester content. It is not the ester list, and it is not delivered hormone.
A multi-ester blend stacks several release curves in one preparation. The headline figure, 250 or 350 or 400, is the total testosterone ester content per millilitre. Two blends carrying the same number can behave very differently depending on which esters make it up.
| Blend | Concentration | Esters | Which esters |
|---|---|---|---|
| Test 400 | 400 mg/ml | three | Enanthate, cypionate and decanoate |
| Test 350 | 350 mg/ml | several | Multiple testosterone esters |
| Sustanon 250 | 250 mg/ml | four | Propionate, phenylpropionate, isocaproate and decanoate |
