This is something i definitely do not recommend doing but the advantage of at home phlebotomies is that you can let a smaller amount at a time and therefore not suffer consequences like malaise or lowered performance in the gym. When i used to do that sh1t i would never let more than 150-200ml at a time.
As far as morality of throwing away the blood while it could be used to help someone, i am not really fussed about it, as first of all i wouldnt be eligible to donate ever again if i was honest about everything i did in the past.
And as far as donating my next cycle, if it becomes a necessity (hematocrit 54 or more), i will let 150-200ml 2x at most at different points during cycle.
Am i a selfish bastard for wasting blood? Definitely not because i do not qualify for donation on at least 2 points in the questionnaire.
And the thought of a little girl receiving a pint of blood filled with a cattle steroid is a little unnerving to say the least.
