On how to inject the oil based steroids is it important about their effectiveness or not? I am not talking about absorption but for the effectiveness of the gear. For example i used to inject testosterone or tren not into the upper area of the gluteus but in the lower( i felt more comfortable there) with 1 inch needle. is it affecting the "power" of the gear or it doesnt matter cause in any case it is injected into the muscle? please help..iam just curious..
