Looking to start cycle 300mg test and either tren or deca. But should i use both or just one and how much? I am 50 now. Used tren at 45 with test 300mg per week and even at 200mg per week of tren my strength increased exponentially every week over 8 weeks. Need advice on what I should or should not take. also tried Primo at 50mg per day while hitting 100mg of test OED. Primo gave me mad headaches! Had to stop the primo. also just started 300mdg AOD-9604 Troche daily to boost fat loss. Any input would be helpful. This seems to be the place to get answers.
