For subQ like hCG the dullness is fine as that’s what’s slin pins were made for (drawing from the same needle you inject subQ with). It can absolutely still be done for IM but it is less than ideal. Personally I do it sometimes out of sheer laziness to backload but it is most definitely not the best option for the long term (scar tissue). I’ve been making more of an effort to not do it as of late. I would do it with hCG 100% though - subQ is no biggie.
can you go more about why draw pin with slin pins for IM causes more scar tissue?
From my interpretation a dulled needle is going to cause more damage to the tissue similar to how if you move the needle, have shaky hands, or use a larger gauge needle, etc. you will do the same - the dulled needle is ‘fraying’ in a sense, so it doesn’t go in entirely smooth how a fresh needle would and damages more surrounding tissue because of it (there are some images available online to show you what the fraying looks like if you’re curious). It’s likely not too significant, and there unfortunately isn’t much (if any?) data on it since slin pins aren’t usually used for IM injections, especially long term, but if you take a new needle and one that has punctured a stopper you can definitely feel a smoother puncture with the fresh needle if you aren’t using the dart technique. It’s likely less significant the less you’re puncturing (so if you’re drawing more than 1 compound it’ll be more noticeable) but this is all speculation through anecdotal experience since we don’t have actual data available. From my perspective needles are cheap enough (like $10-15/100 on healthykin) that for somebody planning to be in this for the long haul it would only make sense to avoid the risk of any added scar tissue since there is really no downside to backloading when possible other than the minuscule financial impact. Similar to how it only makes sense to use the smallest gauge needle possible - the precaution can only benefit you in the long term.
