My progress, looking for some advice.

[The Deadlifting Dog]

So my weight now has gone down unfortunately... I'm now at 172 lbs. which is back to around where I started. I am itching to get back on test but really want to hold onto more of my gains. I am in my last week of my PCT and wanted to know when I can go back on cycle? as above... around 4 months after PCT

Also, given that I am such a hard gainer, what do other hard gainers do to retain their gains while bridging cycles? eat more food and keep training

As always, thanks for you advice and guidance everyone.

my guess is you didn't use an AI... if so, most of your 20lb gain was just water.
You should've used an AI.

also, sust should be pinned at least twice a week if not EOD... once a week is not a good pinning schedule.
