I dont see the point to run primo. Mast is worthless for any type of muscle building - along with proviron, its a cosmetic drug, if it works(for me it didnt).
So all you have is basically 500mgs of test, some primo, and some bullshit.
Id say you would be better just running 1g of test. If u want something extra, do EQ instead of primo. Half the price, same benefit. You can do like 750 test and 500EQ.
The leanness of a bulk is not achieved by artificially adding cosmetic drugs to the mix. Its achieved by eating clean, and less calories in surpluss. You can lean bulk on deca and anadrol and you can get fat on tren and masteron.
