r/PeptideTides

Ranked by what's producing the best results for aging, skin, cellular health, and long term wellness

The order within each tier is not a ranking. They're just grouped by tier not listed best to worst

S TIER

HGH - sleep, skin, recovery, body comp, energy. The most established compound on this list with decades of clinical use. Everything about aging improves when GH levels are optimized

GHK-Cu - the most researched anti-aging peptide available. Naturally occurs in the body and declines sharply with age. Modulates over 4000 genes involved in tissue remodeling, collagen synthesis, and inflammation. Human studies show improvements in skin thickness, elasticity, and wrinkle depth. Works injectable and topical

Thymosin Alpha-1 - your immune system ages just like everything else. Most legitimate immune peptide with clinical use in 30+ countries. Immune modulation and inflammation control are foundational to aging well

A TIER

NAD+ precursors (NMN / NR) - NAD+ levels drop by as much as 50% between young adulthood and later decades. Preclinical data shows restoring levels can improve mitochondrial function, cognitive performance, and multiple aging markers. Multiple delivery routes available

Epithalon - studied for telomerase activation and telomere length. Telomere shortening is one of the hallmarks of aging. Sleep and circadian rhythm support are the more immediately noticeable benefits. Human data is limited but the mechanism is directly relevant

BPC-157 - tissue repair, gut health, and reducing systemic inflammation all contribute to aging better. Pro-angiogenic effects support blood vessel health which declines with age

TB-500 - tissue remodeling and repair. Supports the body's ability to recover and rebuild which naturally slows down over time. Often paired with BPC-157

B TIER

CJC-1295 + Ipamorelin - GH support without injecting exogenous HGH. Sleep, recovery, and body comp improvements all feed into the anti-aging picture. More affordable than HGH

Sermorelin - same category as CJC/Ipa. GH support for sleep and recovery. Clinical history in wellness settings

MOTS-c - mitochondrial derived peptide. Mitochondrial decay is a major driver of aging. Studied for insulin sensitivity and metabolic regulation. Human data is limited but the mechanism is directly tied to cellular aging

SS-31 / Elamipretide - targets the mitochondrial inner membrane directly. Studied for mitochondrial protection and cellular energy. Highly regarded in longevity circles

Semax - neuroprotection and BDNF upregulation. Cognitive decline is one of the most impactful age related changes. Protects dopaminergic neurons and reduces neuroinflammation in preclinical models

Selank - cognitive preservation and neuroinflammation reduction. Neuroinflammation is increasingly recognized as a driver of systemic aging

C TIER

Glutathione - master antioxidant. Detoxification and immune support. Levels decline with age

Collagen peptides (oral) - most accessible anti-aging option. Some clinical evidence for skin elasticity and hydration

KPV - anti-inflammatory without immunosuppression. Chronic inflammation accelerates aging. KPV addresses that through NF-kB inhibition

DSIP - deep restorative sleep is where repair happens. DSIP may support sleep architecture but human data is mixed

Thymalin - immune and longevity peptide. Limited published evidence but immune restoration is relevant to aging

D TIER

Melanotan II - cosmetic tanning compound. Not an anti-aging peptide. Side effect profile makes it hard to justify here

Dihexa - cognitive peptide with theoretical relevance but very limited data and safety concerns around its mechanism

The compounds in S and A tier are there because they address the root drivers of aging. GH decline, immune dysfunction, mitochondrial decay, tissue breakdown, and chronic inflammation. Everything below supports those areas or targets something more specific

I am looking for legitimate medical doctors that support peptide research and study to help convince naysayers that this is not

Bu!!$h1t. If anyone can point me directly to someone with a verifiable alphabet behind their name I would greatly appreciate it.

I’m taking Reta, TRT, Semax, selank, tesamorelin, klow, NAD+, and mots C. I have been taking them for about three months now. I haven’t lost any weight, but I have a ton of body recompositioning. I work out consistently 3-4 times per week. My cardio could improve. Any advice on this stack or things I should remove or add? I’m 43 years old, 6’3” and 280 pounds.

Hey all new to this group I have a question I see lots of Chinese manufacturers selling peptides and 10 vials of Reta 60 mg is almost the price of one vile from an online Canadian source. Has anyone had experience with purchasing from China? If you care to share your source I’d appreciate it. They all seem to have lab tests and say they will refund the money if I tested in the results are not adequate

Thanks for all your information. I do appreciate it. I think I understand why you only refer to American. But unfortunately, there are people like me that really afford the prices. put together

I’ve been using peptide for the past year and a half information on how I can buy directly from a supplier

I never used to and have been pinning reta, GKH, MOTS-c, NAD+ and MT2.

I was fine for about 5 weeks but now i get itchy and a small red lump when I injected everything bar MOTS and NAD (maybe because they are pinned in my leg?)

The GHK i do in my glute and reta and MT2 in my stomach

hey guys, I'm coming off a GLP three (reta) in the upcoming month. I've been on it for about two months now and I'm down about 20 pounds. I'm currently on 4.0 once a week plan on moving up to 5 in 2 weeks but after that, I'm dropping it down to 3, then 1.5, then 1 and stopping completely after that I have history of high triglycerides and high cholesterol, and I would say that I have nonalcoholic fatty liver disorder, but I haven't been diagnosed. I wasn't able to lose any weight before starting reta even though I've always been in a consistent calorie deficit and trained and did cardio multiple times a week i bought 500mg nad+ because I heard it helps metabolically on the come down. I know this is a little bit of a rough. tiration but I only have 15 MG left of my current supply. And I don't really have the money to buy more. If I could have any tips or someone could give me a better plan that would be greatly appreciated.

How long until to see results from KLOW ? I have 50/10/10/10 blend 3ml bac water mix. I ran GLOW for 1 month everyday then took a 2 week break and now on week 2 of KLOW.

Was wondering how i can enhance my KLOW protocol for maximum efficiency.

Current Daily supplements:
10g collagen peptide, 1000mg vitamin c, 11mg Zinc from multivitamin.

When did y’all’s skin benefits show up?
Did you notice it helping with keeping face “not puffy” and slim?
Wanted to know y’all’s experience with running KLOW and the benefits yall had. Along with any cons you experienced.
Hoping it’s not a waste of money or a placebo thing.

Age 24, Male
Side note also on Reta 2mg weekly

Hey - all,

I was wondering whether anybody has any experience traveling from the US to Europe with peptides? I have a trip planned and would hate to have them confiscated. Thanks.
