I am not a personal fan of doing anything solo except testosterone becuase with higher androgenic compounds such as orals the androgen count in your blood stream rises and drops to fast. Anabolic compounds like primobolan, deca, eq, etc are good choices to add quality muscle. The problem with them is that the take 2-4 weeks depending on which compound you choose before they are full metabolized and attaching to receptors to begin working. I would always run a test with an anabolic because you benefit from both compounds properties.
Now there really is nothing wrong with a primo only cycle except primo is really only used during pre contest phases in order to spare muscle while on a calorie restricted diet. Primo in itself isn't a very relable builder in my opinon unless you run it at higher dosages at around 600-800mgs per week if you are going to use it by itself. There are just much better options out there for that, such as EQ or deca. The only problem with deca by itself are its rpeorted affinity to convert to progesterone. Whether it actualy does or not is debatable. But it is proven that deca does reduce libido in men, so taking it by itself might not be the best option.
As far as cost goes you are paying $510.00 for 32 amps. ( Hopefully they are the 100mg and not the 50mg). That comes to 15.9 or $16.00 per
amp. That is much too expesnive even for primo. At most you should pay is 13-14.00 andeven that is on the high end.
Even at 600mgs per week the gains are not going to come as quickly as you like nor to the degree you are probably looking for. If you are worried about side effects then yes primo is a good choice as the side effects such as water retention, hair loss, acne, etc are minimal with this compound, but there are trade offs for everything. You might experience less side effects with primo but you may not get the mescle building effect you are looking for. Hope this helps a bit bro.
