I tried a Sub Q pin of 50mg Test P at the end of a cycle in anticipation of using small ED injections of Prop in the next cycle, and didnt want to do them IM every friggin' day.
It does indeed load in a Slin pin. Very slowly, but injects without problems.
Anyway, it was fine. Little sore the next day and a little lumpy as it took a while to dissipate. 2 days. I would consider this for TRT, or if using something like Emeric's protocol.
To the OP: Shots throughout the day? Do you mean Test suspension? I dunno, but that could hurt like a mother. And if you were to do that, an oil based suspension with some BA in it, to improve your chances of being sterile (avoiding infection). Some sponsors have it. Water-based has stung a lot of Bros with abscesses. Though they're much easier to deal with Sub Q, it would still suck a whole lot.
