I think T-1 Pro is a great 1st cycle, and the 50/50 ratio is fine, but the new gel can hold up to 20g of powder. It will be underdosed with only 10g in there. I suggest 7.5g 1-test/7.5g 4AD, then 1 squirt twice a day will be a perfect dose. You won't start to see gains until the 2nd week, and your big gains will come in the 3rd/4th weeks. So stick with the dose & don't increase when you dont see anything yet by day 5 or whatever. If gains stall after like 4 weeks, only then condsider upping it. If you're still gaining, stick with the current dose. You'll never gain as easy as on your 1st cycle, no need to push it.
If you do keep it only 10g, you may need to bump it up to 3 squirts a day after 2-3 weeks. PS- If you do use 3 squirts just split into 1 squirt morning & 2 night(or opposite), its too hard to get a half squirt out.
