I am on my diet right now and I just got my T3 in the mail. I am going to be doing it along with clen , also have a bottle of primo laying around as well, 10ml 200mg/ml. My question is do you think that 400mg/w of primo would be enough to keep some of my muscle? My biggest concern is losing the fat and can deal with losing a little muscle, just dont want to lose a whole bunch. I really dont have any other use for the primo so thought this might be a good time to use it. Any input would be appreciated.
