Hi, guys…I’ve got a simple question here, does caffeine interfere somehow with test cyp absorption? I’ve been drinking a lot of instant coffee (more than 12 cups a day but somedays I barely drink it) even during the injection day. Some people say caffeine increases SHBG, which is bad for testosterone to be free and available. Can someone please give me a good and short explanation? thanks a lot.
The only thing I can think off the top of my head is caffeine is a vasoconstrictor - it may affect blood flow and it’s a dieretic. 12 cups seems pretty excessive probably not good for general health and adrenal function anyway. If adrenals are taxed cortisol rises - cortisol and T have a negative correlation.
yeah, but you mean it would obliterate the effect of the injections?
Cut out the coffee for a week and find out
If you keep your total caffeine intake to less than 300mg a day then it shouldn’t effect T.
I would say you’re pushing higher than that with 12 cups of coffee a day. I would recommend no more than 3-4 cups a day, or 1 cup in the morning only, if you take other supplements that include caffeine. Also, as was mentioned by @mike12 caffeine constricts the blood vessels. That fact, coupled with the fact that HCT will increase to some extent when injecting testosterone, will start increasing blood pressure over time. Best not to fuck with the affairs of the heart if you catch my drift.
I think you have more to worry about from adrenaline fatigue. That’s a lot of caffeine.
more than 12 cups a day ? bro what the fuck
