deca and test do not necessarily mean higher blood pressure. i've done deca/test for a long time and neither have ever effected my blood pressure. also, these two will not have a huge impact on blood viscosity. somewhat yes, but nothing compared to eq use by comparison. besides, higher blood pressure does not equate to a higher heart rate. in fact, in some instances they will actually be inversely related. i just don't see it coming from the test or deca, especially at those doses.
