Any of you gents start TrT using Retail Test Cyp (Phizer Depo-Cyp) then switch to a compound pharm for Cyp and notice any difference? I been feeling out of wack since i went the compound route, (using a very known compound pharm, one thats mentioned in this forum quite often, also recommended by Nelson Vergal, so i confident its legit. My energy and stamina level has plummeted since donating blood ..which was shortly after starting with the compounded test....going on 3 weeks now and still dont feel back to normal...going to see the doc soon for labs...just curious if anyone else has noticed a difference of any kind after switching to compounded test.
