Never tried Primo but now that I'm in my mid forties I'm thinking it might be a good choice for me so I ordered some oral Primo, taking two a day for now along with some test. I will be ordering some injectable Primo in the coming days, just not sure if I should go with the acetate or the enthanate. I know a lot of people don't like oral Primo because its not a C17-aa, but I was curious about it. I've read a couple of articles about mixing it with Vitamin E or dsmo but I'm somewhat skeptical and I'm not into throwing my money away. Anyway, Swole is always a pleasure to deal with, received this pack in 8 days from time of payment but that's including the weekend and the holiday so I thought that was pretty dam good and his site was down the previous weekend so I'm sure he was swamped with orders.
