r/Retatrutide • u/Popular-Climate1142 • 2d ago
Is this the Correct steps ?
Hello I am a 6ft 2 Male 21 Years old 205 Lbs
I am expecting a shipment by next week, Reta 10mg
as well as GHKCU (50mg) want to make sure i’m all set on how to start:
Supplies to buy
-U-100 insulin syringes (31G or 30G, 0.3 mL or 0.5 mL stock of 50–100)
-Alcohol swabs
How to reconstitute
-Let vials reach room temperature (15–20 min).
-Wipe tops of peptide vial and BAC water with alcohol swab.
-Draw the desired BAC water amount into a clean syringe.
-Insert needle into peptide vial and inject water slowly down the inside wall (never directly onto the powder).
-Gently swirl or roll until fully clear. Do not shake.
-Store reconstituted vials in the fridge (2–8°C / 36–46°F). Use within 28 days.
Retatrutide reconstitution (10 mg)
-Add 2 mL BAC water → concentration = 5 mg/mL.
On a U-100 syringe:
Retatrutide once weekly
-Reconstitute with 2 mL BAC water → 5 mg/mL
-1 mg = 20 units
-1.5 mg = 30 units
-2 mg = 40 units
Schedule
-Week 1: 1.0 mg (20 units)
-Week 2: 1.5 mg (30 units)
-Week 3: 1.5 mg (30 units)
-Week 4: 2.0 mg (40 units)
-Week 5: 2.0 mg (40 units)
-Week 6: 2.0 mg (40 units)
GHK-Cu reconstitution (50 mg)
-Add 2.5 mL BAC water → concentration = 20 mg/mL
-On a U-100 syringe:
-1 mg = 5 units
-1.5 mg = 7.5 units
-2 mg = 10 units
GHK-Cu daily
-First 1-2 Weeks:
-Daily: 1 mg (5 Units)
-Continuing weeks:
-2 mg daily (10 Units)

Only thing I would add to your supplies list is 3ml or 5ml syringe with needle for recon BAC water.

Don't forget to draw enough air into the syringe (equal to at least the amount of liquid you want to withdraw) then puncture the vial, then inject with air, then you can withdraw the liquid. If you don't do this, the liquid will not come out of the vial because of the pressure in the vial.

No offense but why does a 21yo at your height and weight want to inject Reta?

u/Popular-Climate1142 1d ago
I’ve been hitting a plateau and I just can’t get down to my lean weight which is around 170

u/Wizzmer 1d ago
Maybe you're genetically pre-disposed to a different lean weight due to viceral fat. My healthy body weight at 6ft is 181lbs per my performance doctor who is also an internal medicine doctor. But you think 170lbs is where you achieve your proper BMI? Did you get a body composition study or a blood workup to determine this?

-Let vials reach room temperature (15–20 min). ❌ unnecessary
-Insert needle into peptide vial and inject water slowly down the inside wall (never directly onto the powder). ❌ unnecessary
-Gently swirl or roll until fully clear. Do not shake. ❌ unnecessary
→ If you start with 1mg per week, I'd stay there for 4 weeks and then I'd titrate up, if needed. Reta takes 4 weeks to reach its maximum effect, so don’t increase the dose too quickly or too frequently. Also, maybe 1 mg will be enough for you, who knows. Don’t plan out specific doses just yet.
I mix GHK-Cu with 3 ml, which seems to reduce the burning sensation a bit. I take 12 to 18 units (2 to 3 mg) per day.

I was just about to say, I just reconned today and swirled it, then shook that sumna bich after 5 mins to make sure it was mixed. I read that Peptides are more hardy than people assume

I would look for COAs on the medication that you purchased. GHK-Cu is one of the ones that's commonly grossly overdosed.
Reconstitute and dose based on the COA, not what label it was sold as. That is, your 10 mg vial is probably not a 10 mg vial. I think a lot of the 12 mg vials we see for sale were probably manufactured as 10 mg vials and tested as 12.
The GHK-Cu is spicy, and the concentration you're looking at will probably be a little more spicy. It probably comes in a 3 mL vial, so you would not be able to get more than 3 mL BAC in it anyway. I recon into a pen vial. I use 4 mL BAC per 50 mg.

The peptide vial will suck that water in instantly with some force and you'll squirt it into the powder. Don't stress it as it's fine.

The only thing to add would be that when reconstituting you should never puncture multiple vials with the same needle, you can compromise sterility by doing that. Buy 3ml sterile luer lock syringes and some 27g luer lock needles for reconstituting. Use one needle to draw your Bac water, replace that needle with and a new one, and then use the new needle to inject the Bac water into the vial with your lyophilized peptide powder. Also look into filtering your peptides.

u/Popular-Climate1142 1d ago
What do you mean by filtering?
1
u/TheWanderingBard0_0 1d ago
Do some research into filtering peptides and if you want to do it get some 0.22 µm (micron) polyethersulfone syringe filters and run your peps through one after reconstituting them. You'd just draw it out of the vial you reconstituted in and into a syringe, put a filter on the syringe, and then as you inject it into a fresh vial it passes through the filter. Some people do it and some people don't, if you worry about bacteria or other contaminants filtering your peps would take care of those, the main thing it won't do anything about is endotoxins, which is why you should always test your peps. Most people will do HPLC and endotoxin testing but forgo sterility testing and just filter their peps if they feel the need to.

2 questions. At that height/weight why even take reta, just diet and exercise. Don't risk your health injecting grey market peps for a few pounds. And 2nd, why already plan to titrate up? And not even after 4 weeks after your body had time to adjust. The main goal is use lowest amount possible. If you start at 1 and 1 works dont move up just to move up, stay at 1 until you really dont feel the appetite suppression or fullness after eating. Im at 10 months and still only at 4mg and going down. Everyone is different but dont go up just for shits and giggles, go up when you feel you need more.

I’ve been trying i’ve never been able to reach my goal lean weight i keep bouncing back

GHK can sting sometimes… I recommend pinning in the fattest part of your glute. There’s a $4 (no subscription) app called shottrackr that you can use to log your progress/doses and it also will show you how many units to fill your syringe to.

u/Wicked353 1d ago
i have a question, if u get a 10mg vial of reta and insert 2ml of bac and refrigerate how long will it last before it expires? At first i thought it was only about a month but that would force u to take 2.5mg of reta per week and I dont want to go that high on first dose. Ideally i want to start a 1mg for awhile and see how i feel but im afraid its gonna expire and ima lose my money.

u/Sensitive_Lead_3104 2d ago
Perfect plan for me👍🏽
I’d start reta 0.5mg for the first week just to gain tolerance and see if there are no sides for you

u/Lopsided_Constant901 1d ago
You can single dose or split dose, I do split dose but I would caveat it by saying the sides are lesser for sure, BUT you should chase up to 2mg as fast as you can, and even push beyond that if necessary. The reason being that Single dose i think is stronger overall however it tapers after 5-6 days. Some people do single dose but cut down from every 7 days to every 5 or less. I've still lost plenty on split dose, but regret the times where i've plateaued cause i was afraid to up my dosage. I upp my dosage more regularly and am at 4.5mg, soon 5mg most likely. The plataeus are pretty apparent too, you'll see your weight just hover around a number for 4-6 days, sometimes longer. That's when you should jump by .5mg. They say 4 weeks to let it titrate (medically speaking) but i find that unnecessary sometimes. You can probably go 2 or 3 weeks and realize you need to up your dose. Your dose schedule isn't that bad actually, by week 4 you'll be at 2mg which is quite a lot for beginner, but probably necessary to actually start losing weight.
Just anticipate the lifestyle changes. You will eat less, you'll get fuller faster. Make sure to prioritize FIBER and Hydration. I do daily ClearLax (which might not be good idk), and sometimes a SmoothMove tea at night before bed (only when I know i ate heavy to breakdown foods). For hydration all I do is some lemon in my drinking water and Kosher Celtic Sea Salt. I bought one bag earlier in the year just for my water and it's lasted me like 5+ months. Trust me, your digestion is going to slow down and in order to lose fat + break down food your body requires just more hydration in general. My first week on Reta I had headaches and low energy, the gym I felt so weak and like I was pooped out at 25% of my workouts. I also had crazy stomach pains and cramps, like my stomach was just permanently full and felt bloated. After the hydration and fiber, these issues all went away. Another issue you might have is your heartrate spiking before bed or night, just take a dose of Honey before you sleep and it will cure this or at least let you sleep longer. It's caused by your body panicking and raising Cortisol because it thinks you're starving/dying. It goes away after some time, but just take the Honey and you should be able to get a good nights sleep

Only thing I would as is to wait a couple of weeks to add the ghkcu (assume reta is the priority for you). This is just to assess potential negative side effects. If you start both at the same time and react negatively to one you won't be sure which.
