The issue you'll be concerned with for cutting is estrogen-caused water retention. Both T-1 Pro & Final have the same amount of 4-AD per squirt, so you will retain a little water either way. The only difference between the 2 products is T-1 Pro has double the amount of 1-test (per 240ml). The extra 1-test will just be a waste if you are cutting.
You could probably save money & just use 1 bottle of T-1 Final at 2 squirts a day. It should last 4 weeks & should do the trick. You'll retain muscle while cutting, & maybe even gain a little. Not bad for $28.
