I don’t know what it means but it’s on the emblem of the PLA
Wikipedia says this:
The PLA’s insignia consists of a roundel with a red star bearing the two Chinese characters “八一”(literally “eight-one”), referring to the Nanchang uprising which began on 1 August 1927 (first day of the eighth month) and symbolic as the CCP’s founding of the PLA. The inclusion of the two characters (“八一”) is symbolic of the party’s revolutionary history carrying strong emotional connotations of the political power which it shed blood to obtain. The flag of the Chinese People’s Liberation Army is the war flag of the People’s Liberation Army; the layout of the flag has a golden star at the top left corner and “八一” to the right of the star, placed on a red field. Each service branch also has its flags: The top 5⁄8 of the flags is the same as the PLA flag; the bottom 3⁄8 are occupied by the colors of the branches
For the actual vials I’m going to send you a PM with two website that links to E sources. Note that that is only for E. I don’t know where to get T. You don’t need antiandrogens, if you inject large enough doses of E as you body will just stop producing T. Do get bloodwork though to see if the dose is correct.
For injection supplies any online pharmacy store will do. You will need alcohol wipes to disinfect the stopper and the skin before drawing. Use 70% isopropyl non-woven alcohol wipes. You don’t want anything else as it may not disinfect properly or leave fibers on the stopper. If you are doing subcutaneous, I would recommend fixed needle insulin syringes as you won’t be wasting too much E on deadspace with those. Do not use any needles below 23 gauge as that would increase vial coring risk (higher gauge is thinner and better). If you are using MCT oil, you can even go as far as 30 gauge and have no problem drawing. (use a different oil if it turns out that you get allergic reactions to the MCT oil. other oils have the disadvantage of being thicker, but will still work. For subcuraneous, needles should be half-inch or third-inch (in the latter case inject at 90º instead of 45º). The syringes depend on the concentration of the vial and how much you are injecting. I’m using 0,3 mL syringes, with my Estradiol Enanthate of which I inject 5mg weekly (0,10 mL at 50 mg/mL), but I could also use 0,5 mL or 1 mL syringes as those are generally easier to get.
The website recommended by @awth13@hexbear.net has some issues in regards to their anti-coring article. However I noticed a few things:
They state you should always use the same hole for drawing. I don’t know why you would do that. If it’s a sharp needle that’s just going to increase the coring risk as the likelihood of a piece of rubber being cut off is increased. Just use a different spot every time with shap needles. You probably won’t be able to see where you pierced the rubber if you used a thin needle anyway.
Do not use the 45-90 technique. Just insert at a 90º angle. The 45-90 technique can be messed up and isn’t needed if you are using thin enough needles.
They state that coring is not necessarily dangerous but best avoided. I disagree, if your vial is cored, it no longer is protected against the outside world and you should assume that it’s contaminated and that you can no longer safely inject its contents. Do not continue using a cored vial. Use thin 23+ gauge needles to avoid coring.
Note that when looking at tutorials, that some advice is given with a hospital setting in mind, where you aren’t using a vial continuously for more than a year, so please do not listen to people who say you should use 18 gauge for drawing. That’s going to core your vial very quickly.
I also recommend to get involved in a DIY community with a knowledgebase where you can ask questions and see the answers to previous questions.
If you use discord, I can provide you a link to such a community.
