Appreciate the update!
MESO-Rx
Anabolic Steroids
Refillable injector pen
- Thread starter TTK
- Start date
The person who runs that store is a good person, but those are just chinese generic vials. She does a proper job of sterilizing them though. I doubt you'll get much of a discount because it's a labor intensive process.

I've been loving using a pen for my twice daily BPC157/TB500 injections. It's been a big improvement in speed and ease, and it feels like the 2x/day frequency has helped my shoulder issue. Although TBH its impossible to know if these peptides actually do anything or if its just placebo + time.
I setup another pen with test C and I'm not seeing any visual signs of rubber degradation after ~10 days. At my current burn rate a full 3 ML cartridge would last just under 3 weeks. I do like to leave the pen overnight in a wipe warmer which probably doesn't help with rubber longevity.
Anybody been using oils in their pen for a while and have any feedback? Is the only way to know for sure to let the oil sit for 3 weeks and send a sample to jano?

I've had oils in one pen cartridge for over 6 months. Looks the same... As with a lot of things on this forum it's just blind panic.
The rubber on mine is grey not black. So probably a lot more oil/solvent resistant.

I think plenty have, the volume it holds isn't beneficial to me. So I don't personally use for T.
Others mention leaching of rubber chemicals into the oil you inject. I don't know how rapidly that takes effect. I don't know if it's reasonable to ignore or respect.

Yeah, for GCMS
that'd be insightful and informative (take good notes on how long, how hot, what carts etc)

It's Jan 20 2025. Put oil in this Jul 23 2025. (Stromusc Testosterone Enanthate 250 April 2029 exp).
No signs at all of degredation.
Original photo
Day 3. No signs of rubber degradation.
The oil is stromusc test enanthate indicated by supplier to contain EO. Probably BB/BA/MCT +EO.
I'll post another photo in a few days. Looks so far like nothing is happening.

Look at the difference in the colour of a syringe plunger verses these cartridges. There is obviously a different material being used. The syringes are probably natural rubber or a composite. The grey is probably silicone or butyl rubber which is more resistant to solvents....

Thanks for sharing!! Your cartridge/piston look identical to the ones I'm using (grey with those raised ridges):

I've used them for test, tren, deca, and primo. I did every day injections with 29ga needles. I didn't notice any degradation of the vials. I've opened a couple after finding them and the rubber seems fine to the touch. I've got a few vials with the dregs still sitting in them that I'll open in several months.

Another anecdote I should have mentioned:
I was traveling and didn't have many replacement needles so I left the needle attached to the insulin pen and a few drops leaked out each day.
The oil completely destroyed some of the black plastic on the pen.
This happened to two pens.
The solvents can be really bad on some plastics and rubbers.
I've got three used up vials and I'll open one soon and post pictures of the plunger. These are grey plungers and the cartridges/vials are generics from ali Express

Is oil not difficult to inject with a pen and 29G needles? Or is it smooth? I had the feeling zhat 28G is the limit for injecting oils. I’m currently using a pen for my Retatrutide and it’s a big improvement.
