Hi Chaps, been doing 0.3ml of Test E twice / week so 0.6ml / week / 180mg and just had bloods back and super impressed to be 34.6 nmol/L on such a low dose, I've dropped to 0.25ml twice per week so 0.5ml or 150mg as want to just use for TRT, highly recommend this product I've used it for 6 years on TRT and do bloods regularly and it's absolutely on the money, thanks chaps.
