起始剂量和针头相关问题

[zzzthrowawayzzz]

嗨！我终于订购了Reta和GHK-Cu。我做了很多研究，多年来一直被暴食和循环的困扰所折磨，是时候做出改变了。

我在这里看过很多关于针头规格和尺寸的帖子，但我还是想正式地问一下——4毫米、8毫米，还是6毫米的针头更合适？我看到有人说4毫米的针头配合GHK会​​更有刺激感。其实我主要是担心肌肉注射。我对针头不太敏感，但我想只要坚持下去就没问题。我主要是想看看大家的建议和注射技巧，

比如有人说8毫米的针头感觉更舒服。我的体型不算瘦，但可能比这里其他人要瘦一些（我身高6英尺，体重210磅，体脂率27%）。我还有大约50磅的体重想减掉，之前我已经自然减掉了80磅。我主要想知道，你是凭感觉，不把针头完全扎进去吗？等等，跟4毫米和6毫米的针头有什么区别？至于针头规格，我打算用30或31号。这里大多数人说29号，也有人说用31-32号。我不想冒险让针头断掉，但也不想疼哈哈。欢迎大家提供建议。

关于起始剂量，我想慢慢来，但是有些资料说应该从1毫克或2毫克开始。我打算全程都用最小剂量，从0.25毫克开始，看看身体的反应。也许每周一次0.25毫克，或者每周两次0.25毫克，具体取决于情况。只是想听听大家的意见。至于ghkcu，我其实只是因为朋友说应该用，可以预防妊娠纹和皮肤松弛。我看到这个论坛上有人说剂量是1毫克到2毫克。这个剂量合适吗？

任何建议都欢迎，我是个新手，不太会用Pinterest，所以喜欢格外谨慎。

您好，

我的经验是：

GHK-Cu 30G-8mm 注射在臀下部（注射在其他任何部位都会刺痛数小时）。

其他肽类药物 30G-4mm。29G

到 32G 之间的尺寸感觉差不多，在我看来，32G 可能太细了，有可能发生扭转，而且某些密度较高的肽类药物可能难以取出。

I can tell you that you likely wouldn't even feel 27G so I wouldn't worry too much about that aspect. The bending/breaking concern is real, especially if you're talking longer length in the 30-31G range. I would recommend 30G or larger (all the way up to 27G although this isn't as necessary w/water based peptides, more so w/oil suspension injections which we're not talking about here) as the needle is less likely to bend/break, although you'll still want to take care, obv.

As for length, I think you'll be fine w/either of those lengths you mentioned. Both are rigid at their respective lengths and the bending/breaking risk is much lower. Stay away from anything longer as the needles start to get a little flimsy. 31G @ 1/2" (13mm) length sketchy to PIN with.

I was trying to pin around my side to the back of my love handle (this is the best location in my testing for anything w/GHK-Cu in it) and it felt like it broke through and was in properly. I injected and when I withdrew the needle was bent 90deg. I turned to look and had a big blue bump just under the 1st or 2nd layer or skin. I had to use a larger needle to create a hole all the way into the adipose to make sure that it drained properly into the sub-q level where it should have gone. Did some massaging and things worked out eventually, fortunately. Point is, there's a big risk with something like a 31G @ 1/2" (13mm) so I'd stay away from that.

The length you're talking about (4mm vs. 8mm) will make no difference in feeling. You also run basically zero risk of hitting muscle tissue w/those lengths. Especially if you're injecting in your stomach or love handle area and using proper sub-q technique by pinching away a section of fat to target.

TBH I wouldn't stress the difference between the sizes & lengths you've mentioned. If you're doing peptides just make sure to get insulin needles rather then something with a luer lock removable needle. You don't want the dead space that you get from a luer lock for something like a daily use peptide. I'd also recommend looking into something like Glow or Klow as opposed to just straight up GHK-Cu. Those have other peptides that were added (BPC-157 & T-500 to both and then Klow also adds KPV to the mix) to help w/the histamine response to the site to reduce the sting/burn/itch sensation and also add benefits that come with those stacks.

I'd like to circle back to ask a few questions on some of the statements you made that didn't have questions though. You said you were 6ft tall and 210lbs and were looking to drop another 50lbs? Unless I misunderstood, that's an awful lot of weight to lose on that frame. What is your resistance training looking like? It's super important to make sure we're taking steps to add lean muscle, especially as we age. That's going to be a primary indicator to long term health so the earlier you can start building it, the better since it's a lengthy process. How old are you?

Try not to live & die by what the scale says. It's an important metric for monitoring trends but I think that a lot of people tend to look at it as the only sign of success; more, good. less, bad. Your body composition is the important metric to track. This is a little bit more difficult than looking at a number on a scale but it's imperative to overall health. If you plan to use peptides more than GHK-Cu based peps for the weight loss (Reta for instance) it's going to be critical to make strength training using resistance a non-negotiable. If you're adding good lean muscle it's going to be difficult to hit 160lbs @ 6ft tall though. That's why I say that.

It's hard to get a good picture of overall status & goals from a short post on an internet forum though so I'm just going off of the currently available info.

Disagree with the guy above me. For IM , a 4-8mm needle is not likely to reach the muscle if you’ve got a lot of fat. And you’re not even wanting to use the entire length of the needle and “eyeballing it”? (Not sure why you’d even want to do that.)

6-8mm are generally meant for subQ. 4mm are meant for Botox. If high body fat people are using 4-8mm for peps intended to be IM, you’re not getting IM.

This is one of those rare times when ChatGPT is helpful. OP, I put in your height, weight, and body fat for IM needles. You’d probably prefer the 25g, but these can also be found at 27g.

Really im just worried about pinning intramuscular.

Also, you don’t need to pin many peps, like Reta, IM. I use a 31g 8mm (5/16”) for GLP1s.

Maybe I misread but I didn't think the OP was trying to go IM. I read it as their goal was Sub-q and they were "worried about IM" as in they didn't want to go so deep as to go IM. If that's the case, we're both saying the same thing. 4mm to 8mm (and even longer but the OP was asking about those lengths specifically) isn't hitting the muscle.

Hi! I ordered reta and ghk-cu finally. I've done a ton of research and after just struggling for years with the same binging and cycles, it was time.

I've seen and read a ton of threads on here about needle gauge and size, but i'd like to more formally ask - 4mm or 8mm. or even 6mm for these peps. I've seen people say that 4 gives a spicier feeling with ghk. Really im just worried about pinning intramuscular. I'm not the best when it comes to needles but I figure just get through it and it'll be fine. I mostly just wanted to see what people recommend and what techniques help?

i.e. people say 8mm feels more comfortable. I'm not lean by any means but I might be more lean than others here (im 6 foot, 210lbs and 27% bodyfat). I have about 50ish lbs i'd like to lose which i've done before naturally (80lbs). I'd basically want to know do you eyeball and just not stick the needle all the way in? etc as compared to 4mm and 6. as for gauge size, I think im going with 30 or 31. Most people here say 29 and some have reported using 31-32. I'd like to not take my chances with it snapping, but also have it not hurt lol. any advice is welcomed here.

And for starting doses I wanna work really slow, however some resources say you should start at 1mg or 2mg. I kind of planned on being on minimum dose throughout and starting at .25 and seeing what my body does. maybe .25 once a week or .25 twice a week depending upon what happens. Just wanted any advice on this. For ghkcu, i'm really only using because my friends said I should to avoid stretch marks and loose skin. I see 1mg-2mg doses on this forum. Is this about right?

any advice is welcome, I'm a super newbie when it comes to actually pinning and I like to be overly cautious.

If you can easily pinch the area then you probably aren't going to hit your muscle.

BUT ... if you aren't that big then you probably aren't going to get stretch marks and loose skin either. I mean unless you are old or something.

Yep, exactly. Thank you both, I was more worried about the mix of not going deep enough and going too deep and accidentally pinning IM.

Thank you for the GLOW/KLOW comment as well. I've obviously heard about many different peptides but i've always had good skin so I never researched them until my friend said I should take ghkcu for stretch marks and loose skin. I started reading up on GLOW the other day. I'm fair skinned, so I do scar easy. Definitely something I'm interested in.

As for your other comment I'm 22, so I'm generally young. I grew up overweight and lost a lot of weight over the span of a few different cutting cycles and developed an ED around freshman year of college. Before that I had tracked everything really well, hit protein goals with a low fat diet to help hunger signals, and was 150 around 12% and looked decent. During that freshman year of college I cut down even more (ED actually started) eating just protein supplements and energy drinks and got to 129 scale weight sub 10%. Was a crazy time of my life and was really skinny but I looked pretty cool with my shirt off.

I don't want to get near that again. but naturally the story went, you get a girlfriend and you no longer have the self control as your ghrelin spikes and I spent the next 2-3 years yo-yo or just binging. I'm 27% body fat around, might be a tad lower now but not a crazy difference, so I have 155 lbs lean mass and I believe my scan showed 82lbs of muscle although I'd have to double check. I don't have a ton of muscle, but I'm also not untrained. I think your concern is definitely valid and it's possible I'll have to reassess at 180ish, but I am trying to push down to 11-15% again and maintain. My guess is around 160 ill be 15-18% as you naturally lose lean mass with fat mass. Hopefully with reta I just strip adipose tissue, but need that discipline hitting protein goals and training.

Thank you for all the comments, I think i'm going with 30g 8mm although I'm tempted to do 6mm.
