Unfortunate cirrcumstances and I no longer have enough cyp to make it through my cycle which was just test. cyp. 250mg every 4 days. My source cant get any cyp for about another 2-3 weeks but has some Sustanon 250 ready to give me. Can I still shoot that every 4 days even though it has Prop and phen? Or should I just not change over to the sus? I already missed 1 injection and don't want to go a month without it. Any suggestions please.
