- 0:00Host explains how to submit questionsThe host asks viewers to check earlier episodes before sending questions and says the doctor is filmed only every few weeks, so answers take time.
- 1:35Viewer asks about repeating GHRP-6A 34 year old viewer reports gaining weight on GHRP-6 and a fasting glucose rise from about 80 to 103. He asks about risk, side effects and adding a steroid cycle.
- 3:09Doctor on danger and legal statusThe doctor says he does not know of any particular danger and notes the peptide is not FDA-approved in the US, leaving legality abroad to the viewer.
- 4:09Why fasting glucose may read highHe says athletes often eat more the night before a fasting test, which can raise the number, and recommends HbA1c as a three to four month average instead of a single reading.
- 6:11Appetite and growth hormone effectsThe doctor says GHRP-6 raises GH, which tends to raise blood sugar, and also increases appetite. He suggests extra eating may explain the viewer's result.
- 7:14Stacking with a steroid cycleHe says GH works better with anabolics, so healthy testosterone would help, but whether to use steroids is up to the viewer.
- 8:51Carbs after GH peptide injectionsA viewer asks whether to hold carbohydrates after injecting two growth hormone releasing peptides post-workout. The doctor says carbs within about half an hour work against the goal.
- 11:28Bedtime dosing and insulinThe doctor suggests a bedtime injection on an empty stomach, argues against insulin for this purpose, and ties what he calls GH belly to insulin use.
- 14:22Gilbert's syndrome and testosteroneHe sees no contraindication to testosterone with Gilbert's syndrome, calling it benign, and says the liver is not at risk of failing from it.
- 16:30Why liver warnings exist on testosteroneThe doctor recalls that methylated testosterone was thought liver friendly but proved hard on the liver, and says the cancer link was weak.
What the video says
This is an "Ask the Doc" episode from MuscleInsider, recorded in 2015. The host reads viewer questions and a physician, introduced as Dr. Ren, answers them. The captions are auto-generated and garble some names. After a short housekeeping segment about how viewers should submit questions, the episode covers three questions, two of them about peptides.
The first question comes from a viewer who gained weight on GHRP-6 and saw his fasting glucose rise from about 80 to 103. He asks whether a second run is risky and whether he could add a one-time steroid cycle. The doctor says he knows of no particular danger. He notes the peptide is not FDA-approved in the US and that legality elsewhere is up to the viewer. He suggests the glucose rise may reflect bigger evening meals before a fasting test, or the growth hormone effect on blood sugar, or the extra eating GHRP-6 drives. He describes an HbA1c test as a three to four month average that is more informative than one snapshot. He also says growth hormone tends to work better alongside healthy testosterone, and that the steroid decision is the viewer's own.
The second question asks whether carbohydrates should be avoided after injecting a growth hormone releasing peptide, and whether insulin should be used. The doctor says that if the goal is to raise your own GH, eating carbs within about half an hour works against it, because insulin competes with endogenous GH production. He suggests a bedtime injection on an empty stomach as one option, and says post-workout can also work. He says he does not favor insulin use unless someone has type 1 diabetes, and he links what he calls a "GH belly" to insulin use.
The last question asks whether steroids are safe with Gilbert's syndrome. The doctor sees no reason testosterone would be contraindicated, describes the condition as benign, and mentions reported cardiovascular associations. He also gives a short history of why methylated oral testosterone earned its liver warnings. None of this is a substitute for medical advice, and the doctor says himself that his GHRP-6 answer is a quick curbside view without the full history.
On each compound
GHRP-61:52
The doctor says GHRP-6 raises growth hormone through a different mechanism and also increases appetite. He says some bodybuilders take it about 30 minutes before a meal for appetite rather than for GH, and that this may explain the viewer's higher glucose.

The doctor mentions a 1 through 29 growth hormone releasing peptide he says is legal in the US (the captions garble the name). He suggests taking it at night on an empty stomach so it supports natural GH release during sleep.

- The doctor gives a curbside answer without the viewer's full history, so the cause of the glucose rise is never established.
- The half-hour carb window and the bedtime dosing suggestion are stated as his view, with no studies or data cited.
- The captions garble the peptide names in the second question, so exactly which compounds are meant is unclear.
Questions this video answers
Can GHRP-6 raise fasting blood sugar?
The doctor says growth hormone tends to raise blood sugar and GHRP-6 increases appetite, so higher eating could also be a cause. He suggests an HbA1c test rather than relying on one fasting reading.
Should you avoid carbs after a GH releasing peptide injection?
According to the doctor, carbs within roughly 30 minutes work against the aim because insulin competes with your own GH production. He suggests an empty stomach, such as after a workout or at bedtime.
Does the doctor recommend insulin with GH peptides?
No. He says he is not a proponent of insulin unless someone has type 1 diabetes, and calls it counterproductive in the injection window. He also attributes the so-called GH belly to insulin use.
Is testosterone safe with Gilbert's syndrome according to this video?
The doctor says he can think of no reason testosterone would be contraindicated, describes the condition as benign, and says the liver is not at risk of failing because of it. This is his opinion, not individual medical advice.
