We've discussed this enough already. Time to focus on other things.

I should admit my own fault in this as well, though not nearly as bad, haha. I've gone a whole twelve months without any trouble, but I wouldn't suggest handling things that way. Shifting to a different subject, I've got nothing more to add right now.

I reckon it's best if I don't spread this kind of detail around because it isn't meant for everybody out there. Plenty of folks trying things lack even simple supplies like that at home, and some get drawn in by methods that seem straightforward.

Apparently some folks skip Amazon subscriptions but still get weekly drops of wipes and a pallet full of u100 syringes.

I went through the whole discussion feeling mostly shocked yet somewhat amused so now I figure it's just someone stirring things up for fun.

People keep bringing this topic up over and over so here is my latest update. I have settled on keeping a dedicated needle for each substance I am using. That adds up to four separate ones right now. Each syringe stays labeled so there is no mix up. The daily one has already gone through five straight uses while the others have seen three or four. They have not lost their edge and I figure each can handle at least fifteen total. This setup is how I plan to continue indefinitely and nothing short of extreme pressure would make me switch. Cost plays no role in the choice at all. Any different approach would simply strike me as pointless and I suspect others would agree once they thought about it. If someone sticks to a fresh needle every single time purely out of personal routine that is fine with me. Yet anyone who panics at the thought of reusing a needle on their own body has my sympathy.

BrightSignal76archiveNov 20, 2025

A few times I've carried on with the same needle in one go. Not very often. They get dull really fast so the hurt just doesn't make sense.

Your reaction to my views is making me concerned for your well-being. I thought sharing my cautious yet straightforward take might help some folks gain basic judgment they seem to lack, yet I underestimated just how easily frightened and easily swayed many turn out to be. Plenty of moments have left me let down by others, but the final straw came when strangers confronted me inside a big retail store over my choice to skip a face covering, even after staff offered one. That led me to ask a higher power for a gentle end to our species, since most appear too foolish to keep going while the wiser few suffer for it. A similar moment hit after leaving a late gathering around three in the morning and spotting a huge crowd stretched out along the road. When I asked, they explained the wait was for a new pastry shop's early opening, and it struck me that standing around for hours just to grab some fried dough means we've forfeited any claim to staying on this world. I bet a lot of the shocked readers here were probably part of that same crowd. Anyway, people should follow whatever feels right for them while I stick to my own path.

I blocked that jerk so his stupid antics stopped showing up in my view.

KeenMeadow10archiveNov 21, 2025

I want to express thanks to the moderator responsible for handling that 😂

IronWillow10archiveNov 21, 2025

I'm thinking it could have been that particular user. The mod should know we care deeply regardless of anything.

SlowLantern99archiveNov 21, 2025
↳ replying to @IronWillow10

No way. I would've just nuked the whole thread and doled out some short suspensions rather than staying so easygoing, so count yourselves lucky. Unless folks here settle down and ease off the intensity though, those moves are still options I could take.

After three decades as a nurse I've come across many infections tied to people reusing needles. One case involved a man who ended up missing a portion of tissue. Still your call on what to do. This isn't meant as any kind of personal criticism but comes straight from my professional experience.

It seems pointless to try changing his mind, what a shame.

NorthSignal19archiveNov 21, 2025
↳ replying to @KeenAlder60

Man, that must really hurt. I'm working to talk myself into feeling okay about it all, though I'm still not fully there. To help calm any worries, I apply disinfectant solution generously and quite frequently. With luck this keeps me from losing any pieces of my own skin.

ClearWillow59archiveNov 21, 2025
↳ replying to @SlowLantern99

I'm wondering why you chose not to erase that instead. Stuff like this might end up causing issues from quite a few angles.

NorthSignal19archiveFeb 2

Just checking in here. For more than eight weeks I've stuck to my plan of reusing one needle across a week or so and applying it to multiple compounds each day. Still nothing bad has happened at all. No signs of any problems like redness or irritation. I'm going to keep on with this approach indefinitely since it hasn't caused issues so far. Two full years of daily use without any trouble means there's no reason to switch methods. The whole notion of fresh needles every time seems pointless to me now.

Out of idle nosiness, though I have zero plans to attempt anything like this, I keep wondering what kind of needle thickness and length gets chosen. After dozens of draws plus dozens of skin pokes, that tip must lose its edge quickly. I can't picture my own skin tolerating more than a few repeats with the same one. How do you handle the repeated jabs without issues?

NorthSignal19archiveFeb 2
↳ replying to @QuietAlder20

These thirty gauge needles suit my needs just fine. Since I handle only a couple peptides total, one lasts me through roughly ten shots until I notice it losing its edge.

NorthSignal19archiveApr 8

I've kept going with my routine even though many here disagreed with it. I reuse the same syringe across different compounds for several days before switching. So far nothing bad has happened at all, no swelling or anything else unusual. I wanted to post this follow up in case those who worried about my safety are still here.

Laughter here, glad about the update! Folks keep tigers living with them and issues rarely come up.

I spotted something and it reminded me of you though the choice is ultimately yours since your body belongs to you.

LevelTimber64archiveApr 9
↳ replying to @NorthSignal19

Newcomers shouldn't copy that habit in my view. Most syringes out there get manufactured for one shot only. I'm mentioning it to help prevent trouble. Keeping sterile conditions counts when you inject questionable substances into yourself. That kind of behavior looks careless and unsafe.

BrightMeadow28archiveApr 9

I draw the liquid up using a separate needle every single time and swap it out right before the shot.

SteadyLedger26archiveApr 9
↳ replying to @CopperFenwick68

Yeah, that thought really creeps me out when considering any dirt that might end up in the stuff being used for shots. Fresh gear for every single use adds better protection and doesn't cost much at all. Just one case of sickness could lead to major trouble.

LevelTimber64archiveApr 9
↳ replying to @BrightMeadow28

Thinking about switching over to the lock style syringes for my research supplies.

PlainAlder11archiveApr 9
↳ replying to @LevelTimber64

Grab the bigger longer ones. Just joking if anyone takes it seriously.

NorthSignal19archiveApr 23
↳ replying to @WryLedger88

Having dangerous animals as pets would shield you from other threats, so the comparison falls short. Some keep even deadlier ones and usually get away with it until it turns deadly.

NorthSignal19archiveApr 23
↳ replying to @KeenAlder60

That picture is nonsense. The tip would break before it bends. It does get dull though.

NorthSignal19archiveApr 23
↳ replying to @BrightMeadow28

If you actually do that you're being completely foolish.

WryLedger88archiveApr 23
↳ replying to @NorthSignal19

Calling someone a moron for trying to lower risk? Sounds like you're just trying to stir things up.

SlowBeacon94archiveApr 23

That picture and the whole thread brings back a scene from that old movie.

WarmLedger35archiveApr 23
↳ replying to @WryLedger88

This is clearly meant to provoke. Even if real, I'd expect them to combine everything into fewer vials to stretch the needle use further.

NorthSignal19archiveApr 23
↳ replying to @WryLedger88

The issue is with that whole risk reduction idea. Does anyone here actually think things through? Switching needles after drawing adds extra steps that could introduce contamination instead of preventing it. It's not even paranoia anymore, just pointless.

NorthSignal19archiveApr 23
↳ replying to @LevelTimber64

Exactly, drawing then swapping needles just creates one more chance for something to go wrong. No other way to describe it.

NorthSignal19archiveApr 23
↳ replying to @CopperCompass90

There's an even simpler and cheaper option with wipes that cost almost nothing. I've kept doing it this way for years and have no plans to stop.

BrightMeadow28archiveApr 23
↳ replying to @KeenAlder60

Tried the low cost ones once and they wouldn't even go through the skin.

BrightMeadow28archiveApr 23
↳ replying to @NorthSignal19

Around here the wipes are about the size of a coin. I switched to larger pads and a bottle of high strength alcohol instead.

SteadyLedger26archiveApr 23
↳ replying to @NorthSignal19

A fresh needle mainly ensures sharpness for the actual injection. With proper technique contamination is already low, but extra caution is fine. Calling it moronic goes too far though. Some just want to cut down every possible variable.

SlowSparrow81archiveApr 23
↳ replying to @NorthSignal19

Alcohol does not eliminate every type of bacteria. Switching needles adds protection rather than removing it. Next you'll claim the wipes kill everything just because nothing is visible.

PlainAlder11archiveApr 23
↳ replying to @BrightMeadow28

I've said the same before. Only certain brands work for me. The stopper does not dull the tip the way some claim. Tried the idea briefly then dropped it.

BlueAlder28archiveApr 23
↳ replying to @NorthSignal19

This poster is quickly becoming my favorite here. A nurse with decades of experience told me changing the needle every time is wasteful and that diabetics usually keep the same one until the pen is empty. The packaging even matches that with equal numbers of each. Maybe there's something to it after all, though the approach still seems off.

ClearMeadow73archiveApr 23
↳ replying to @SlowSparrow81

Correct, it cleans but does not fully sterilize.

NorthSignal19archiveApr 23
↳ replying to @BrightMeadow28

Again with the exaggeration. The ones I've ordered have all worked fine for multiple uses unless your skin is unusually tough.

NorthSignal19archiveApr 23
↳ replying to @BlueAlder28

So you agree with me completely yet still label me a fool? Listen to what you're saying. At least you showed enough sense to see the practical side. Thanks, that settles it.

PlainAlder11archiveApr 23
↳ replying to @NorthSignal19

Earlier I mentioned the cheap ones felt rough. My partner also disliked them. Maybe a different brand than what I tried.
