Stomach Cramps During Workout....mid cycle...need help ...suggestions

OK Bros...need some help

I am 5 weeks into a nice light cutting cycle

500 mg. Boldenone per week
500 mg. Masteron per week

Things were going great...feeling tight, slim, hard...and good energy in the gym...

So I added some BD Winstrol tabs...50 mg. x 2 a day...cuz I heard they were great for cutting. Also added the Himilayan Liver support at 4 before bed.

I feel fine except when I start to lift. I can do cardio no problem...but the minute I start to strain in a lift....my stomach goes into SEVERE KNOTS! I mean like not little cramps...I am talking like OMG I may very well double over and fall down pain. Feels like I am going to shit myself and puke all at once. This is two days in a row now. I am not taking anything else other than whey protein and that has not changed a bit.

Does winny give anyone cramps like this? Am I taking too much? Is it a bad idea to mix Winny with EQ or Mast? Could it just be my chemistry and Winny. Since that is the only thing I have changed...I am clearly backing away from the Winstrol...just curious to see if anyone else has experienced such a thing.

Age: 39
Height: 6'3"
Weight: 245 lbs. around 8% bf
Lifting experience: over 20 years
Roid experience: over 20 years (usually deca and tren and sust...this is my first EQ, Mast cycle and first time using Winny or any oral for that matter!)

Thanks for the help in advance guys.... I am a high pain tolerance person...but literally cannot finish more than two sets without this kicking in. It is like my stomach is caught in the blades of a blender...no joke!
