Injection site soreness after Follistatin 344 – any tips to reduce it?

Posted by quiet_ironman in Safety & Side Effects - 8 points, 3 comments.

Hey folks, I’ve been running a short 15‑day cycle of Follistatin 344 at 100 mcg subQ each morning, mostly to see if it helps with my shoulder recovery after heavy lifting days. About day five I started noticing a dull ache and a little redness at the injection spot that lingered for a day or two. I’ve been using the same spot in my lower abdomen each time, rotating only a few centimeters over.

The discomfort isn’t bad enough to stop me, but it’s annoying and makes me wonder if I’m doing something wrong with the technique or needle size. I’m using a 29 gauge insulin syringe, injecting slowly, and I always clean the area with alcohol first. Has anyone else hit this kind of soreness with Follistatin or similar peptides?

Would switching to a smaller needle, injecting more superficially, or changing to a different site like the thigh help? Any advice on minimizing injection site irritation would be great. Thanks!

  • runner_aaron: Tbh, I’ve had similar with peptides before, same spot, same needle, and it just kept irritating. Switched to rotating more (like thigh or upper arm) and it calmed down. Also, maybe check if the needle’s bent or you’re accidentally hitting a nerve. You said you clean with alcohol, any chance it’s not fully dry? That could cause irritation. Would a smaller needle (like 30g) make it worse or better?
  • quiet_ironman: Thanks for the tips, runner_aaron! I’ll try rotating further, maybe thigh or arm instead of just abdomen. I do wait a minute or two for alcohol to dry, but maybe it’s not fully absorbed? Also, if 30g makes it worse, I’ll stick with 29g. Any other adjustments to test?
  • quiet_ironman: Agree with rotating more, maybe thigh or arm next time? I’ve had that happen too with any peptide if I’m not moving the spot enough. Check the needle isn’t bent (maybe test it first?), and yeah, alcohol drying time matters. I’d stick with 29g unless you’re really irritated, smaller might just poke more. 🔬
