A Shoulder Surgeon's Six Rules for Responsible Peptide Use

Peptides are having a moment. Patient interest in BPC-157, growth hormone secretagogues and other compounds for surgical recovery has grown dramatically — and so has the misinformation surrounding them.

Forums, online vendors and wellness influencers have built an ecosystem where patients self-administer compounds with real mechanisms, real effects and real contraindications — without labs, without physician oversight, without understanding why sourcing and timing matter as much as the compounds themselves.

Rule 1: Monitor labs — before, during and after

Peptides that modulate the growth hormone and IGF-1 axis are not inert. They change measurable biology — and that biology needs to be measured. A baseline IGF-1 level before starting any GH secretagogue tells you where you are starting from and establishes a reference point if adverse effects emerge.

You cannot optimize what you are not measuring. Anyone using peptides without baseline labs is flying without instruments.

Lab monitoring at protocol milestones — typically at four to six weeks and again at twelve weeks — tells you whether the intervention is working as intended.

Rule 2: Know your source

This is the rule the peptide community most reliably ignores — and the one with the most immediate safety implications. Peptides from gray-market vendors have no FDA oversight, no mandatory sterility testing and no accountability if the product is contaminated or mislabeled.

A peptide that is 60% pure is not delivering a predictable 60% of the intended dose. It is delivering an unknown quantity of something else — via injection, into a post-surgical patient.

Rule 3: Match the protocol to the biology

Rotator cuff repair and shoulder arthroplasty proceed through defined healing phases — inflammatory, proliferative and remodeling — each with distinct mechanisms and windows of opportunity. A compound driving angiogenesis is most valuable during the proliferative phase, weeks one through six.

Timing is the protocol. Compounds without phase-matched timing are expensive noise.

Rule 4: Optimise the substrate

Peptides are signal molecules. But signals without substrate produce nothing. If the raw materials for collagen synthesis are not present — adequate protein, collagen precursors, vitamin C, vitamin D, zinc — the signal has nowhere to go.

Peptides are the construction crew. Nutrition is the building materials. Sending a world-class crew to an empty lot accomplishes nothing.

Rule 5: Get post-operative imaging

Post-operative MRI is the only way to know whether a rotator cuff repair has actually healed. A patient can have full strength, minimal pain and excellent range of motion — and have a re-tear. The clinical exam does not reliably distinguish healed tissue from organised scar.

Rule 6: Screen contraindications first

GH secretagogues elevate IGF-1, a mitogenic signal. In a patient with active or recent malignancy that signal is not benign. This is an absolute contraindication, and it is not detectable from symptoms alone.

If you are not working with a physician who knows your labs, understands the healing phase biology and has reviewed your imaging — you are not following a protocol. You are self-experimenting.
