Standard Labs sells research peptides exclusively to qualified researchers and laboratories for in vitro and laboratory use. Please confirm before continuing.
By proceeding you affirm the statements above are true. Products are not for human or veterinary use, not for use in diagnostic procedures, and have not been evaluated by the U.S. Food and Drug Administration.
Nineteen compounds are discussed for size, strength and recovery. This guide keeps the measure attached: what the study tested, what changed, and whether it was a scan, a lift or a pain score.
Growth hormone signals, repair peptides and experimental agents are read the same way. Study type comes before the benefit, dose records are marked unverified, and no compound is graded. No dosing advice.
Not a ranking and not a protocol. Every profile runs the same questions, so two compounds can be read side by side without one getting a better edit than the other.
A scan can track muscle size or lean mass. A lift or force test measures strength. A recovery study might track pain, range of motion or time to return to a task. The guide names the measure before the result.
In a six-month HIV lipodystrophy trial, deep belly fat area fell by 34 cm² with tesamorelin and rose by 8 cm² with placebo. In a bowel-surgery trial, ipamorelin moved a gut measure from 32.6 to 25.3 hours — not statistically clear.
Some repair profiles rest on rat tendon studies. One knee-pain report had no comparison group and looked at 12 people. TB-4 and TB-500 are different forms. Regulators have flagged several of these products for safety gaps.
Plus: a 19-name index, six biology questions, a page comparing study outcomes, a plain-language glossary and the sources behind every profile.
The guide groups research questions rather than ranking compounds. The grouping is a reading aid — not an evidence score, not a treatment category, and not a statement that any of them is safe for human use.
Ipamorelin · CJC-1295 · Sermorelin · MOD-GRF-1-29 · Hexarelin
Tesamorelin · GHRP-2 · GHRP-6
BPC-157 · Thymosin Beta-4 · TB-500 · DSIP
IGF-1 · PEG-MGF
Andarine · RAD-140 · LGD-4033 · MK-2866
SR9009
The groups overlap. A compound can sit in more than one research question, and the guide says so rather than forcing one label.
This one keeps the measure attached. A scan, a lift and a pain score are three different results; the guide says which one the study used — and when the study was in rats. A trial result is not a recommendation.
You have seen a peptide called “healing” or a SARM called “muscle growth” and want to know whether the study measured size, strength or pain — and whether it was in people.
You want a stack, a dose or a promise. Trial doses are study groups, forum amounts are unverified, and SARMs are experimental agents — not a shortcut.

Open the peptide calculatorAdults reading about muscle, strength and recovery research who want the evidence and the limits in the same place. No lab background is assumed. It is not a clinical manual, a protocol, or a review of Canadian approval status.
Yes. The PDF is free. We ask for your email so we can send it, confirm your consent and follow up with a short series on reading a recovery claim. You can unsubscribe at any time.
No. The guide is educational material for research. It does not tell you what to take, and it does not replace a licensed healthcare provider. Some compounds discussed are prescription medicines or unauthorized injectables in Canada. Products referenced are supplied for laboratory research use only.
No. Where a trial assigned doses, those are printed as study groups, not recommendations. Amounts reported in forums are marked unverified. No compound is graded strong, moderate or weak.
No. SARMs are a separate class of experimental agents with their own trials and safety questions. WADA’s 2026 Prohibited List includes SARMs and several hormone-related compounds covered in the guide. The guide does not recommend them.
Because they arrived without a study, a test group, a date or a named author. Reprinting a number is not the same as validating it, so every number is printed with its status attached.
A reading map, six biology questions, a 19-name index, 19 compound profiles, a page comparing study outcomes, a plain-language glossary and the sources behind each profile.
Some of them are in the Canadian research catalogue. The guide is not a ranking of what we stock, and a catalogue listing does not validate any claim about a compound.
A confirmation, the guide, then a short series over a few days. After that, occasional research updates. Every email has a one-click unsubscribe.
No. We do not sell or share your email with third parties. The form stores your name, email, interest and consent record so we can honour your preferences.
