Hey guys was in mexico and couldnt bring my test prop with me. Ended up using testoprim-d (1cc/day) which is a mixture of test prop and test ananthate. I wasnt sure the doasges of this product and after researching upon getting home realized injecting everday was not the best idea because the content of ananthate was much higher than the prop. Like some of you i got test flu and still have some symptons. Aches, fever, pain/swelling around injection site. All i can suggest to people who have this consistent feeling with any type of anabolics is lowering your dosage if you inject more frequently, or if you inject less frequently try splitting that large dose into two or three dosages. Other suggestions to help any possible pain is using a larger gauge for your needle, 22 1" or 23 1" are very common inject size needles (remember the larger the number for gauge the smaller the needle), dont go smaller than 23 1" as it will be to small and hard to push fluid through. Also take a quick brush up on your injection sites on body (least painful being glutes, shoulders), make sure your hitting the right muscle and holding needle on a proper angle based on injection site desired. Best of luck to you all.
