My lab rat over worked his little legs on his wheel, so I got him a little something to help him with his leg muscle and tendon.
Genpeptide has good prices, fast shipping and secure discrete packaging.

Just found out about this type of research and looking forward to all there is to learn and discover. I have several genetically and chronically sick rats that I hope to aid in this research. I am sure I will learn a lot from all of you and hope to contribute back one day. Happy to meet you all.

Tucson-based company with a solid selection of research nootropics and powders. I find their peptides generally overpriced, but their bulk powders appear to be better value from my estimation. I’ve ordered from them several times without any issues and was generally happy with the product quality. I can verify their MT2 definitely gave my rat a dark tan.
Unfortunately, my most recent order went wrong. I placed a ~$195 order that included four items, but they only shipped three, the $85 bottle of enclomiphene was missing. I emailed them twice regarding the missing item and never received a response. It’s disappointing that a relatively straightforward issue like this wasn’t addressed.
I had a good experience with them previously, but this situation has made me hesitant to order again.

UPDATE: After a couple more email attemps, they did make it right & sent me the missing package! Great vendor.

Hey @Randy, you want to know how to get all the girls to swoon over ya?
By doing a giveaway like this one!

You can stack our very own discount code. It’s an unreal sale.

UPDATE: as others have mentioned Amazon has this mislabeled, false advertising. I received my order and there was only one box of 200 pads!

I requested a refund they are asking me to return the box, unlike others they were able to keep theirs.

Sorry folks, I guess when it looks too good to be true it usually is sighhh…

Curad is on back order.

I picked up some Dynarex pads on AMZ (2000) pads for $6 pretty good deal

Just in case any anyone is looking.

I am curious if anyone else has had experience with them, good or bad. My wife ordered GLP-3 for her research and has had great outcomes over the last 7 weeks. It seems like it’s a newer company and there isn’t a lot out there about them, so just curious about any feedback from the community.

Awesome company to deal with. UPS lost my order, not due to genpeptide but I ended up eventually getting it. They kept in touch with me the whole way and said they would even send out a replacement if ups did not find it… they found it and delivered it to me and everything was there and packaged well… will definitely do business with them again

Review

I placed an order with Instant Peptides and paid in full. They ran a Father's Day discount with the word NOW in the ad — no fine print, no time window, just NOW. When I contacted them to cancel and reorder to apply that discount, I was told I was "nickel and diming" them. Let that sink in — I asked about their own advertised promotion and was accused of being cheap. After that exchange, they made the decision to redirect my FedEx shipment mid-transit before it ever reached me, then refused to issue a refund. I never received the product and never got my money back. Complaints have since been filed with the FTC, the Illinois and Arizona Attorneys General, and the FBI's Internet Crime Complaint Center. Sharing this so others can make an informed decision before ordering. Unfortunately I can't attach and upload the transcript.

Have a 120lb female that would like some advice on dossing? She is currently researching KLOW 2.5mg daily and Reta 0.5 each week. Considering 1mg each day of SS-31. What time of day?

I noticed the majority of posts on this site with regard to Pinealon research because of sleep issues. I'm wanting neuro benefits of memory, clarity, etc.

Is there anyone here who's gotten benefits other than better sleep?

I also see most info favors researching it in morning hours. I don't want kitty to fall asleep at work...

I previously bought Dihexa from Limitless bio chem, but tbh i'm not feeling any difference after 3 weeks of using it. I have heard people saying they saw difference as week 1, so I'm curious which would be a trustworthy vendor to buy from for the best quality.

This is at least the 2nd time this has happened with a vendor. I will not send any of them my DL info. Sent them a refusal note on the grounds that I already had an account with them and they sent the order through. (Other than that, I like their products.)

I hope this doesn't become a habit with vendors.

On another thread here was a discussion of TB4 and BPC157, 1 to 1 ratio in premixed formulas not being accurate with regard to the individual dosages of the two. I agree with this assessment and since I cannot afford to dose kitty individually, I'm going to try Cartalax first and see if it resolves any of the joint and other tissue pain she has. As we all know, the cost of peptides can be prohibitive, at least for us.

Any comments/information is welcomed. Wish cat the best. She's old and hurting.

I completely agree with Chad here, something is definitely off with this vendor. I’m into my fourth week on their batch, and honestly, it’s been a total letdown. Not only am I getting zero noticeable results from my usual dose, but I’ve also suddenly come down with a brutal headache and stomach pain. There’s a chance I just caught a bug from someone who was sick around me, but the timing is just too sketchy to ignore. When you get none of the actual benefits but all of these random, miserable side effects, it really makes you question the purity of what they're shipping out. Just like Chad said, the difference between a solid vendor and this one is night and day. On another note, my MOT-C effects seems fine.

For research use only. Not medical advice.

The goal:

Tirzepatide = GLP-1 + GIP
Survodutide or Mazdutide = GLP-1 + Glucagon
→ Combined effect = GLP-1 + GIP + Glucagon, i.e., a retatrutide-like profile.

Because both second agents have a glucagon hit, titration must be slower than usual to avoid nausea, low appetite floor, or excessive gastric slowing.

Why do this?

1. You stockpiled too much tirz.
2. Break a stall.
3. Reta itch/allodynia or other intolerable side effects when researching reta.

1. Tirzepatide + Survodutide

Survodutide has a stronger glucagon hit than mazdutide. This is the more potent combination.

Weekly Titration Schedule

Weeks 1–4

Tirzepatide: 2.5 mg weekly

Survodutide: 0.3 mg weekly
Purpose: Establish baseline tolerability. Survo kicks hard early.

Weeks 5–8

Tirzepatide: 5 mg weekly

Survodutide: 0.6 mg weekly
Notes: Appetite suppression becomes extremely strong for many subjects here.

Weeks 9–12

Tirzepatide: 7.5 mg weekly

Survodutide: 1.0 mg weekly

This is the sweet spot for most research models. Strong “reta-like” effect emerges.

Week 13+ Maintenance

Two viable approaches:

Standard Maintenance

Tirzepatide: 7.5–10 mg

Survodutide: 1.0–1.5 mg

High-End (Aggressive) Maintenance

Tirzepatide: 10–12.5 mg

Survodutide: 1.5–2.0 mg

Only for researchers replicating the high-end metabolic punch of retatrutide.

Notes

Survodutide plus tirz amplifies appetite suppression so hard that most people do not need high tirz dosing.

Escalate slowly — both compounds slow gastric emptying.

This combo is more GC-heavy than mazdutide, so itch issues are less common compared to retatrutide, but GI load is higher.

2. Tirzepatide + Mazdutide (Ghetto Reta v2 — Milder, Cleaner)

Mazdutide has a slightly softer glucagon hit and a less aggressive appetite cliff.
This stack is smoother and usually more tolerable.

Tirzepatide + Mazdutide

Weeks 1–4

Tirzepatide: 2.5 mg weekly

Mazdutide: 2 mg weekly

Weeks 5–8

Tirzepatide: 5 mg weekly

Mazdutide: 4 mg weekly

Weeks 9–12

Tirzepatide: 7.5 mg weekly

Mazdutide: 6 mg weekly

This combo mimics a “mid-dose retatrutide” effect without the itch or violent GI spike.

Week 13+ Maintenance

Tirzepatide: 7.5–10 mg

Mazdutide: 6–8 mg

High-End (Not common)

Tirzepatide: 10–12.5 mg

Mazdutide: 8–10 mg

Notes

Mazdutide is smoother but still synergistic with tirz.

Appetite suppression is strong but less harsh than survo stacks.

GI load increases if escalated too fast — keep 4-week steps.

My rat name Extropy has been researching for 5mo with great results. From metabolic reset, mitochondria optimizing, mental health, longevity, immune and yes she went all in. She is filtering all the peps into pen cartridges as suggested here. In one sitting Extropy has been able to push a set of 2-4 cartridges through one 33Gx4mm pin tip. After she finish the pen tip it gets discarted. She hasn't had any issues. Anyone doing the same or?

One of the vendors I use mainly have test results from AFI. I cannot find any information about them anywhere on the internet. I have seen reddit posts stating they are fake. I have seen your review saying they are not, but it somehow still seems sketchy. Others have stated their methods for testing are not exactly up to Janoshik standards. At this point I don’t mnow what to believe and am just looking for a more believable reason to trust them. I have inventory that I have not touched because of this. Any help is appreciated. Thanks in advance

Note: If you want Tirz (Zepbound) from ELilly, you get quick pens, no other options. I'm spoiled now since joining this forum and want to determine my own doses but there are GREAT options now for those who want and need them.

I have taken MOTS-c since November (with breaks worked in). I have been doing 10mg per week, split into 3 injections. This past week I decided to split the same dosage into daily injections. I made it 1.5mg per day, for ease, so actually doing 10.5mg a week. I have never had the itchy welt others reported. Lowering my dosage, but doing it daily, they changed. After the 3rd day I have developed itchy welts. I am switching back, but this doesn’t make sense to me?
