Halodrol original version not new gaspari version, worked well for me in the past with Trenavar / Trendione, I ran halodrol at 100mg per day and trenavar/trendione at 90mg-120mg for 8 weeks. I was eating at a deficit of around 1000 calories + per day for 8 weeks and still managed to gain around 1lb per week.
I have used Trestolone, at a dose upto 100mg per day oral version by Olympus labs and dropped it after 3 weeks due to a gyno scare, it gave me puffiness in both nipples and extreme tenderness and pain. I will not be running trest again and much prefer trenavar. for all out mass and if you are not gyno prone then trest would be better for bulking but can be watery due to aromatization, if you want dry clean gains which I personally prefer I would go along with trenavar at 90-120mg per day.
