Confusing. In a post above you said no AI, now you say you have a-dex? Intramuscular injections are just that inside the muscle and thus no a sub-q will not be basically the same. Its the reason for the redness and swelling. Finally how do you know the dose of tren your on will be tolerated by your body and not give you prolactin related problems? If you dont have personal experience you dont know for sure and thus should be prudent. Some guys will get gyno with 400mg a week of test and others can take 2G and be fine. The key is not what the standard average is but what you individually require and until you know for sure have the proper precautions in place.
