Where to Get Peptides for Muscle Growth Online: Choosing a Provider
This page covers where and how to get these prescribed, and how to judge a provider. What each molecule is, how the growth-hormone axis works and what the research shows is in peptides for muscle growth and recovery.
You get peptides for muscle growth and recovery online through a telehealth provider where a physician licensed in your state reviews a medical intake and a licensed US 503A compounding pharmacy prepares the prescription in your name. The peptides used around training, growth-hormone-axis secretagogues such as CJC-1295 / ipamorelin, sermorelin and tesamorelin, the growth factor IGF-1 LR3, and repair peptides such as BPC-157 and TB-500, are prescription medications, and none is FDA approved for building muscle. At Pepti the most commonly prescribed option, CJC-1295 / Ipamorelin, is $239 a month all-in, covering medication, physician review, refill management and shipping, with no membership fee.

The short answer
| Question | Answer |
|---|---|
| Do you need a prescription? | Yes. Compounded peptides for human use are prescription medications |
| Are they steroids? | No. GH-axis peptides signal your own pituitary; steroids act on the androgen receptor |
| Who prescribes? | A physician licensed in your state, after reviewing your intake |
| Who makes it? | A state-licensed US 503A compounding pharmacy, for one patient |
| Are they FDA approved? | No. Compounded medications are not FDA approved |
| Do you need bloodwork? | No. If your physician wants labs for your care, they'll ask through your account |
| What does it cost at Pepti? | $219 to $289 a month all-in, depending on the product |
| How do you start? | The free online assessment |

Why the source matters more in this category
This is where the grey market is biggest
Training forums are where research-labelled vials get passed around most, and "for research use only" means no prescriber, no pharmacy accountable for identity or strength, and no sterility requirement. A 2010 paper in Growth Hormone and IGF Research analyzed a black-market IGF-1 LR3 product and found a manufacturing tag still attached to the peptide. The molecule you inject is only as trustworthy as the pharmacy that made it.
The claims are biggest too
This category has the widest gap between marketing and data. Anyone advertising a secretagogue as producing steroid-like size, or quoting pounds of lean mass, is not describing the pharmacology. A provider's claims are a quick test of whether it is practising medicine or selling.
Tested sport
Growth hormone releasing factors and secretagogues, including tesamorelin, CJC-1295 and ipamorelin, are prohibited at all times on the WADA list, BPC-157 is named under S0 and TB-500 under S2.3. A real intake asks whether you compete in tested sport. If you do, check with your anti-doping body and tell your physician before starting anything.

The provider checklist
1. A physician licensed in your state
The prescription is valid only if the prescriber is licensed where you live. Check on your state medical board's free license search, or see how to check an online peptide doctor is licensed.
2. An intake that asks the right things
For this category a physician wants to know about sleep, protein and training, glucose and insulin sensitivity, any cancer history (growth signalling matters there), and tested sport. A form that asks none of that is not a review.
3. A named, licensed 503A pharmacy
Ask which pharmacy compounds the vial and check it with the state board of pharmacy. Pepti's pharmacies are PCAB-accredited, FDA-registered US 503A compounding pharmacies.
4. Published lot testing
A certificate of analysis should name the lab, lot, method and date and report identity, purity, sterility and endotoxin. Pepti's are at lab results; see how to read a peptide certificate of analysis.
5. One all-in published price
Medication, physician review and shipping in one monthly figure, shown before you start.
6. Honest claims
No "FDA approved," no muscle amounts, no timelines. None of these peptides is FDA approved for building muscle.

The training and recovery options at Pepti
Which product fits is set by your physician after reviewing your intake. The table helps you compare the same product across providers.
| Product | What is in the vial | Usually discussed for | Price |
|---|---|---|---|
| CJC-1295 / Ipamorelin | 6 mg CJC-1295, 12 mg ipamorelin in 5 mL | Recovery between sessions and deeper sleep | $239/mo |
| Sermorelin | 10 mg sermorelin in 5 mL | The same goal with a single shorter-acting molecule | $229/mo |
| Ipamorelin + Sermorelin | 10 mg ipamorelin, 10 mg sermorelin in 5 mL | Two GH-axis receptors in one vial | $219/mo |
| Tesamorelin | 10 mg tesamorelin in 5 mL | Body composition alongside recovery | $249/mo |
| TITAN | 10 mg tesamorelin, 6 mg CJC-1295, 12 mg ipamorelin, 10 mg BPC-157 in 5 mL | Recovery plus a nagging soft-tissue problem | $289/mo |
| ASCEND | 6 mg CJC-1295, 12 mg ipamorelin, 10 mg tesamorelin, 1 mg IGF-1 LR3 in 5 mL | The GH axis with IGF-1 LR3 included | $289/mo |
| IGF-1 LR3 | 1000 mcg IGF-1 LR3 in 5 mL | Direct growth-factor signalling, prescriber-led only | $259/mo |
| BPC-157 + TB-500 | 5 mg BPC-157, 5 mg TB-500 in 5 mL | An injury that is limiting training | $259/mo |
CJC-1295 / Ipamorelin, sermorelin and BPC-157 + TB-500 are also available as a pre-filled Pepti Pen cartridge, which holds a different amount of medication from the vial and has its own directions. IGF-1 LR3 and ASCEND carry the most cautions, because IGF-1 signalling lowers blood glucose and growth signalling matters with any cancer history. Comparisons are in CJC-1295 vs sermorelin, CJC-1295 vs tesamorelin and ipamorelin vs CJC-1295.

Legal status, briefly
All of these are legal to prescribe and compound with a valid prescription. None is FDA approved as a compounded product.
| Molecule | Status as the live reference pages give it |
|---|---|
| CJC-1295, ipamorelin | Withdrawn from Category 2 in September 2024; the advisory committee voted against adding each to the 503A Bulks List in late 2024 for the uses it evaluated; neither appears in Category 1, 2 or 3 of the list updated 14 May 2026; no final FDA determination |
| BPC-157, TB-500 | Removed from Category 2 on 15 April 2026; the committee voted 8 to 6, with one abstention, on 23 July 2026 to recommend each for the 503A Bulks List; final determination pending |
| Sermorelin | Not in any category; its footing is its history as the active ingredient of a previously approved drug |
| Tesamorelin | The active ingredient of an approved drug, so never nominated to the category list |
| IGF-1 LR3 | Not in any category; the FDA has published no position on it |
A committee vote is a recommendation, not a ban. More detail is in are peptides FDA approved.

What the evidence shows, honestly
The best evidence on raising growth hormone in trained people comes from trials of growth hormone itself. A 2008 systematic review in the Annals of Internal Medicine found it increased lean body mass in young, fit adults, but strength and exercise capacity did not appear to improve. A secretagogue working through your own pituitary does not reproduce those doses. Sermorelin has studies in older adults showing restored growth-hormone and IGF-1 levels, and tesamorelin has phase 3 trials for visceral fat, but neither measured strength or performance. There are no randomized human trials of IGF-1 LR3, BPC-157 or TB-500 for muscle or injury.
So the realistic case for this category is recovery, sleep and training consistency on a plausible mechanism and a limited evidence base. A provider that promises a muscle number or a timeline is promising something no study supports. Training, protein and sleep are the stimulus; no injection replaces them.

Common questions
Where to Get Peptides for Muscle Growth Online, answered.
Through a telehealth provider where a physician licensed in your state reviews your intake and a licensed 503A pharmacy compounds the prescription. At Pepti, start with the free assessment.
