4th real cycle...coming to a finish.

[Maxspeed996]

Been a member a while and haven't had many posts, mostly here to educate myself. Finishing my 4th cycle in the past 2 years. And don't know what to think about the Test E that I'm currently running. My cycle history has been very simple.
Cycle 1 - Test Cyp 250 2 x week. 12 weeks. UG Lab same brand all the way through
Cycle 2 - Test Cyp 250 2 x week. 12 weeks. Same UG lab all the way through
Cycle 3 - Test Cyp 250 2 x week. 12 weeks. ISIS brand all the way through
Tren Ace 50 2 x week. 6 weeks (to see how my body reacted to the Tren)
Cycle 4 - Test Cyp 250 ISIS brand 8 weeks and had to switch to another brand of Test E for the final 4 weeks of the 12 week cycle.

I noticed that I just felt good on all first 3 cycles, and on cycle 4 I still have that great feeling of well being, and strength feels sold, but I don't notice any increase in what I consider a normal libido while on the test e. Could the final vial I've ran be fake? or would I notice an increase in my libido while on this? I also notice increased soreness in my injection points with this product. Should these things be red flags?

no input at all? libido was through the roof at the beginning of this cycle and after switching from the cyp to the Enanthate it's nothing close to what it was. Is this because of a different substance having to build in the blood stream? I would think that the Cyp's long esther would carry it in my blood long enough for the Enanthate to level out at least a decent amount. This pain at the injection points seems to go away after about 3 days. Should you use your libido as a sign that things are working properly? I would think there would be a significant increase over normal....and I feel ....normal.
