yea, i would not run test any longer than 15- 16 weeks....everyone respnds different...but hcg might help out with recovery if ON for that long...i would run eq for 15 and one more inject of test at minimal dose on the 16th week and use winny as a bridge into pct...eq at 15 weeks is the best....i have used it at low does at 15 and greatly improved my 2mile run and 12 mile ruck march...
