Injection procedure - test cyp in cottonseed oil

[trtthings]

I've recently ditched the 18g drawing needle for a 27g (same as I inject with).

I'm finding that half the time when I stick the needle in the cyp bottle and pull down on the plunger, I get no test/oil.

I generally start by drawing 0.2ml of air into the syringe which I inject into the cyp bottle first.

Drawing more air in seems to help. Does anyone have any tips regarding this?

A second thing is, I inject into the quads, a lot of the time I get some swelling afterwards. Are there any tips for this other than injecting slowly? I'm aware it's not considered best practice but I also "aspirate" prior to injecting.

First, how much are you injecting? I assume 0.2ml...if not, there’s your problem.

I’ve heard people say TC in cottonseed is “thicker” than grapeseed but I’ve honestly never noticed a difference, and I use 29g and 30g needles to draw and inject.

Steps (leaving out sanitization, etc):

-Draw air into syringe - should be the same volume as the volume of oil you will draw out.
-Insert needle inject air into vial.
-Invert vial/needle.
-I compress the plunger, then draw back. This is likely unnecessary but may help in starting the vacuum.
-Draw back way past where you want to measure. For example, if I’m injecting 0.3ml and using a 1ml syringe, I’ll draw the plunger back to a bit past 0.7ml and let it fill to the 0.4ml mark.
-I then depress the plunger to inject excess oil/air back into the vial.
-Once oil is at desired measurement, flip vial/needle right side up, remove, inject.

As a side note, once a vial is almost empty (one or two draws left), I inject maybe twice the amount of air.

I've found that warming the vial makes a huge difference for drawing/injecting.

Post injection, massage the area a bit to distribute the oil in the muscle. I've also used a heating pad on the area for a few minutes with success but massage usually works fine.

Grapeseed oil is definitely thinner.
I use a 29g with cottonseed...it takes a little longer to draw the first 5 or 6 doses. I inject a full 1 cc of air with each dose. By the 6th dose, there is enough air pressure in the bottle, if force fills the syringe. After that, I add about .2ml of air each draw. Doesn't take me more than 15 seconds or so. I use depo, not the pharm fabbed stuff.
