Test is the safest compound, cycling on 1g of test only is often more safe than stacking several compounds at low dosages with higher toxicity.
The body do not care about how many digits you are injecting.
With 1000mg of test, I have almost no sides, and it doesn't affect the sleep, libido, appetite etc.
My bloods remain good and healthy as well (lipids and liver enzymes), no elevated BP.
With 500mg test and 200mg tren e, I sleep less, and it sometimes kill my appetite for some reason Idk
with 500mg test and 400mg deca, my libido isn't top
and on both, I have higher cholesterol, and slighly higher liver enzymes compared to test only cycles.
Low dosages 19-nor in general (200-400mg) are much more toxic than the extra 500mg you gonna add of test to have 1000mg weekly dosage.
Neuro toxicity, BP problems, libido problems, mood changes, thyroid and cholesterol.
