Peptide vial transfer methods and needle choices for repeated injections

Not really concerned about the sensation, more about getting the shot in the right spot and avoiding muscle. With 4 to 8 mm you can just go straight in without thinking about angles.

The length I mentioned does not bother me. I just want to know from experience whether angling keeps it reliably subcutaneous and avoids going too deep.

Not too long if you pinch the skin first. That length matches the pre-filled subq syringes I get on prescription.

Yes, 4 mm or 6 mm are the usual for pens, though I ended up with 5 mm for some reason.

If the current length feels too deep you can always switch to shorter ones later when body fat drops. Or just try not inserting as far if you cannot find shorter ones right away.

Slightly off topic, but pen needles really are nice. I used pens for a month then switched back to a 29 g insulin needle to get the last drops from a vial. The needle just bounced off my skin and I had to stab harder the second time. Probably because it had dulled going through the stopper plus the bigger gauge.

That same bounce happens sometimes with my prescription pre-filled syringes. Been using those every other week for over twenty years. I just move an inch and try again. Never had that problem with the 31 or 32 g ones I use for GLP-1 shots.

Same here, I do not want to switch. The small size is perfect.

Pinching the skin helps keep you from worrying about hitting muscle.

I pinch a bit and go straight in with no angle. Curious how the 6 mm feels, let me know. Those sizes are fine. How many milligrams are you taking? 31 g needles are good but can be slow drawing from vials, not because of vacuum. Room temperature vials help a little. I have a couple hundred so I will get used to it, just takes a few extra seconds. My 30 g was quicker to fill.

To walk through the whole process so someone can say if it is wrong: adding 1 ml bac water to the r10 vial means two full 0.5 ml syringe fills. Or I could do four fills of 0.5 ml totaling 2 ml and then 10 units would be 0.5 mg instead of 1.0 mg. First dose 0.5 mg this week, then 1.0 mg the next week for two weeks to see how it goes. Which way is easier?

No 1 ml syringes?

That is what the store gave me yesterday, so no, not at the moment.

Definitely going to get a larger syringe for mixing next time, that was a pain. Took six to eight minutes just to reconstitute, guessing that is normal. Moving on.

You seem to be mixing up units and milliliters. A 0.5 ml syringe holds 50 units, so four fills would be 2 ml or 200 units total.

Thanks, ended up just adding 1 ml to the r10 vial to keep it simple. First time doing this.

I checked online needles but most say they are not sterile, so I stick with pharmacy ones. Only issue is the length they stock, though this thread shows people make it work.

Straight in? Not worried about going into muscle? A lot of online sources say that length often ends up intramuscular.

Best way until you move up to the bigger vials. Which one are you on?

Zero concern. I pin growth, BPC, and TB every night with a 12.7 mm needle.

The 29 g ones do poke a bit more than the 31 g. My wife hated the 30 g I had. I only had a few and was using them for something else. The 31 g do bend, mostly when going through the stopper. I have it down now, dead center helps a lot.

If you get sterile vials and transfer your peptide into one after filtering, the thinner self-healing caps are easier to pierce with skinny needles and do not dull them as much.

I tried the center but I must be too rough or something. The needle even bends when I pin sometimes. Needle pokes do not bother me for subq though. I do not think I could ever be an IV drug user though.

Lots of sellers go with the thick stoppers instead. Those aren't built for pulling out doses again and again. I moved the contents into another bottle that seals back up on its own.

I do just that but the stopper does not seem any more forgiving than the vials the powder ships in.

Huh? The items I purchased match those available at the drugstore. Aren't they labeled as self-repairing? They're intended for repeated applications.

I got some empty vials coming before I make a new batch this weekend and hopefully they have thinner plugs. I still have about 80 of those thin needle syringes left. The ones I use for reconstituting are thicker, around 26g I think.

They are self-healing sterile non-pyrogenic vials. I just do not find them any or much easier to pierce than the lyophilized powder vials.
