Been seeing deca come up a lot lately so wanted to get a proper thread going with honest profiles rather than just the usual hype. I ran deca at 400mg alongside test e at 600 for 20 weeks last offseason and the gains were as real as advertised. Size, strength, joints all improved and I was holding more water than expected even with e2 dialled in, but the fullness looked good on a bulk so I didn't fight it too hard.
The deca dick is not a myth. Weeks 8 through 12 my libido tanked. I had test above the deca dose the whole run but didn't have HCG going and I think that was the mistake. Added HCG at 500iu twice a week around week 10 and things came back. Prolactin stayed in range on caber 0.25mg twice weekly but I wouldn't skip that either.
Long ester so you need to plan for it. I dropped deca 3 weeks before my last test pin and the timing still meant markers were elevated weeks after. If you're anywhere near a PCT or cruise transition, account for how long it lingers.
Worth it for a proper offseason bulk in my opinion. Post your own experiences, especially around the libido management side because that seems to be where most people run into trouble.
