Sick man yeah spectrum is awesome just as good and actually I think smoother then zphc , zphc is a thinner oil but spectrum has a smoother oil and is alil thicker, spectrum use to have a video of there lab and facilty and it was deff super high end high tech production line to everything was super clean all in suits and hoods , it deff was impressive idk if u ever got a chance to see it, they deff had a legit enough lab to produce quailty gh for sure, well I'd keep using it cause u look great man I can't wait to see updated pics pretty wild physic , nice relief when u know ur gear is high end and good clean stuff, in the video u could see the amount of raws it was like damn they don't need to underdose they had that much it was deff nice to see iv been saying for awhile that zphc and spectrum is a really good lab it's finally catching on , I know alot of Russians use it that was where I found in the beginning alot of the bloodworks and lab testings and hplc tests everything was coming back good I was glad RB got it and brought it in and brought it in for a good price , keep smashing it man u look great very nice balance also
