Sure, you’ll be fine with some decent liver support. Just make sure you are keeping an eye on things. Plenty of guys only take orals pre-training.
Greg Panora said in a recent podcast when he set his first ATWR total he was only taking 400mg test/wk and one Dbol tab every training day because that’s all he could afford. This is when he was like 19-20 and living out of his car in the Westside parking lot, and Louie probably gave him the gear for free lol. And John Meadows said on Fouad’s podcast the other week his very first cycle was just one cc of veterinary grade Winstrol every other day for 60 days pre-contest. His training partner had nicked it from his Dad’s business so he had to make it last
Also consider you could probably just run 20mg phera per day instead of pulsing 30mg, FWIW.
