what is the biggest reason for post-inj. soreness and swelling?? i can't understand why so many friends are crying and screaming about how enan at 250/ml gives them major soreness as well as swelling..its not infected cuz it goes away on its own..and made exactly the same way, i use enan. at 425/ml plus 1-test cyp at 170/ml (1-test cyp is the most irritating injectable on earth) is enanthate supposed to hurt or is there something wrong w/ my raw materials??
