L-Carnitine - SubQ vs IM

This is a really interesting question. I’ve been taking 600mg L-Carnitine via IM with a half-inch 27g needle in my shoulder 1-1.5 hours before working out. I haven’t tried SubQ yet, but I think it might relate to how the compound absorbs.

Thanks for the quick reply. I was thinking that the reasoning behind IM being preferred was due to the absorption rate, but I was curious about other opinions on SubQ to see if there was any solid evidence regarding the differences between both methods.

Dude, spare yourself the massive lump and welt, and just go IM. I tried SubQ once and ended up with a huge bump on my stomach for three days. Plus, there’s quite a bit of post-injection pain, so be careful about where you inject.

Last week, I foolishly injected 2ml of 500mg/ml L-Carnitine into my left lat and the post-injection pain was insane! I couldn’t use my left upper body properly for days! I’d recommend IM, preferably in the glute if you have to.

I recommend IM if you're determined to use it. Both methods have a fair amount of post-injection pain, but for me, IM feels like a moderately sore muscle for about one or two days—nothing worse than after a workout. SubQ, however, burns painfully for around 30 minutes and then feels like a major bruise for days, and I started getting sore lumps too. To be honest, the benefits didn’t seem worth it for me. I didn’t notice much improvement, and it was my most painful injection. After a couple of weeks of daily use, I was over it. Plus, it’s not exactly cheap.

I suspect that SubQ would cause a lot of post-injection pain. I diluted my 600mg/ml L-Carnitine to see if it would help, and it did a little, but I still felt it for a day or two. Honestly, I haven’t seen much benefit and prefer other peptides.

Yeah man, I’ve been using it for four weeks now and I’m not convinced the post-injection pain is worth the benefits. My backside is sore as hell for days.

I found better success using a more concentrated version at 1200mg/mL, allowing me to only draw 0.3mL for my dose. It fits well with my daily Test C in the same syringe.

L-Carnitine can be a bit painful, so you might want to try IM instead.

I've been doing SubQ, and it definitely stings a bit, but I don’t experience severe post-injection pain. I can’t tell if it’s the L-Carnitine or the needle, but it’s about a 50/50 chance of getting a small bruise afterwards. As someone else mentioned, I’m not sure if the results are worth the trouble.
