I saw in another thread on here that you could stack 1-Test with it. Well what i have is about 60 cc's of LMR Primotest..which i believe is the same as VPX 1-test(Proplycarbonate) with an extra 5mg. and about 70 cc's of LMR Nandrotest. Could i Do the Nandrotest for the 1st two weeks then the primotest for the last two weeks while doing SD for the whole 4?
