My question is does anyone know the correct half life for testosterone phenylpropionate? I've read different things on it some suggesting that it's half life is almost equal to test prop, others suggesting that it's a slow releasing ester.
I am more inclined to believe the second opinion because half life is dependent on solubility in oil which is determined by the number of carbon atoms the ester has......prop has 3 and phenylprop has 9, which would make it longer than cypionate(8 carbon atoms)
I am thoroughly confused and would appreciate some input. Thanks
Here's some of the info i found
